What other "personalities" should we add to our robots?

If you’re looking to make different personalities, you could have an aggressive one that purposely drives into other robots when it sees them. Or maybe one that looks for one-block gaps and then steers towards them to try and make as many cuts as possible.

We should NOT have "priority left turning". It should be randomized. This can be achieved with painting the arena in 2-color noise input that a bottom facing color sensor on the robots can detect. Use that noise to determine if you turn left or right.

Crazy sensor idea: Back-side robot sensors for strategy: If you see a robot with your back but not your front, those sensors having a longer reach, turn towards it to cut it off.

As for the hole sensor, maybe have one that's pointed *almost* straight down on both front corners that's linked to the existing ones. That way, you'll catch holes that are right next to the vehicle as well as slightly further out. All this automation stuff gave me an idea for a multiplayer spleef arena. Add a shootable target to the back of each vehicle. Triggering it inverts the left-right controls for 5-10 seconds.

So. . . we aren't gonna do 2 middle sensors so that the robots could "walk a tightrope"? Essentially an inversed line-rider. I feel like that kind of intelligence is important in spleef.

Randomness can be done using timers. Either click in a pattern using a button, or try to make a 'linear feedback shift register' using a few timers and gates.

I think a cool personality grouping would be "the avoider" - "the aggro" - "the ignorant" and I don't have a fourth one. The avoider would work like current blue, the ignorant would fully ignore other bots and the aggro would turn towards other bots as long as there's no hole that way instead of away from them. Who would win that match?

Spleef with friends and robots! Big map.

The ramps cause the sensors to trigger (or untrigger rather) causing them to turn their default direction, thus they turn left off the start. Without the ramps they don't seem to be significantly affected by the turning of the platforms. I suspect it's because they hit the pieces that are straight and it causes them to straighten out somewhat. As for Ideas, my initial ideas for personality would be default right, default left, reduced vehicle detection range, and can't drive straight.

you should challenge the guys to give their own bots some personalities

I think the next personality should include a timer that will make it turn left if no sensor for x seconds every y seconds or right if no sensor for x seconds every y seconds to mix things up.

Put sensors in front of the robots to prevent them from driving into narrow holes

What about Sniper spleef? No seats on the car, players are up on walkways above the arena, and have to remote control their spleef drones by shooting buttons on them. Of course you can also directly shoot the floor, but that means less time managing your drone.

What you could do for the platforms is some sort of sensor that detects when all the robots are off the platform, a wall forms, then it flies away. This should make it so that robots don't go back on the platform

This is what happens to me every time i try to improve something. I somehow make it objectively worse.

It would be cool to have a random turning left, a random turning right, a random turning both ways and a no random turning in one arena.

So we didn't randomize the paint of the arena itself so that we can use a bottom facing color-sensor for a source of RNG? Shame. We can still do that for a "Chaos Personality".

Fantastic long term series idea with the community battles and your own evolutions battles, look forward to it all.

16:30 the robots can’t see in front of them so they drive straight in the hole. So you need a forward facing sensor and if it detects a hole the robots goes left (this could be different in every robot to give them different personalities). The forward facing sensor should of course be lower priority than the side sensors so it doesn’t steer the robot in a hole right next to him but if both side sensors detect a hole and the forward sensor the robot should probably go forward and not turn left. If have a forward facing sensor you can make the side sensors look slightly more to the side (maybe 50°) so they see too the side better. For how far a sensor should look, it should detect the holes just far enough that it can just turn around while turning towards the hole (this happens when all the sensors detect a hole). If the robots looks closer it can’t avoid the hole anymore and it becomes useless to know there’s a hole if it looks farther it maybe looks over a hole it could avoid. This of course means that the side sensors should look farther than the front sensors because of how a turning radius works.

Omg, Kan you are a genius. I'm of course smarter for pointing out how you just invented Open Plan Maze Spleef. Take a Spleef map and add random walls with lots of gaps for vehicles to fit through. Now you can't see what the others are doing whilst also having to plan your route and traps around walls.

I would love to see a community ai spleef tournament

Personality idea: "the scared one" if it sees a hole or other robot it just turns away in a 180 turn and runs away from everything!

Especially in scenarios like this one where you are only testing 2 personalities on 4 bots, having 2 left favored and 2 right favored rather than all left favored would help increase variance as bots will react differently to hitting the far edge.

For random turning, you can just have a loose bearing that has a rod that just barely sticks out, similar to a AD converter. Then with simply just a sensor to detect it, and a timer to choose how often it happens, you have random turning. And maybe add a sweeping motion to the hole sensor.

You could change the starting platforms to all have different settings on rotation so it truly is more random. Some personality ideas: Aggressive: tries to cut off others and even ram them Scared: looks further away and will avoid everything at all costs. Dizzy: sways left and right instead of going straight Regretful: will try to make full U turns whenever encountering holes and other bots And if you want even more personality. You can make some drive and/or turn faster or slower, have different sensor settings, maybe even have some be able to boost, jump, have more guns, or use pistons.

It's nice to see that even with the end of Rooster Teeth, Red vs. Blue still lives on.

A large spleef arena filled with bots that you compete against alongside other players would be neat but I wonder how well that would work. You could make it single winners, pair people off with a bot, or people vs bots.

Multiplayer idea: add a turret on top of the robots for the players to control, and maybe give some ability to turn, but add a cooldown to it

Hi Kan, here ive got an idea to maybe make the robot move a little more natural. how about you spam blocks over the arena of 3 different colors and whenever a bot drivers over suchs blocks they will turn a certain radius.

My suggestion for the "antennae" with the sensors would be to make them sweep back and forth, stopping when they find a hole so that they have a while to send out that signal that they've found a hole. I did something similar to that when making the center turret on my farm defenses, and I think it might work well here, too.

1:50 welp...that's certainly an interesting, uh, shape.

Changing how they interact with other robots might be a good idea. Either make them not care at all about other ones or purposely drive into them.

I would really like to see these robots get developed more and more :)

you should put two sensor antenas facing the front and angled down put them above the end of the wheels so you can make sure that the path isnt too thin) and wire them up so when the side facing antenas both not see ground but both the front antenas are seeing ground it will drive straight and if both the side dont see the ground and one front antena is it will turn to the other direction so it can drive on thin paths (put them above the end of the wheels so you can make sure that the path isnt too thin)

Use a timing setup to randomize turning L/R but priorities the sensor. You could also put the hole sensors on a piston with a timer or controller to increase and decrease throughout the game

Love this! Evolve them to the ultimate spleef machine then bring along to MM spleef! 🤘

Put sensors on all 4 corners facing down to detect holes in conjunction with the other sensors, in combination with "@Hadeks_Marow : We should NOT have "priority left turning". It should be randomized. This can be achieved with painting the arena in 2-color noise input that a bottom facing color sensor on the robots can detect. Use that noise to determine if you turn left or right."

You could make a Multiplayer spleef where you include an AI robot competing with you guys

Maybe they need more than 2 directions. They only _really_ need to turn when the path is missing directly in front of them but that's where they struggle most. They dither until it's too late.

Im really excited about this!

You could have the robots maybe team based where they do different actions depending on what color robot they see? And randomized turning just for variability too would be nice.

A *simple* addition, since you're already using a Controller to set the angle of the sensor antennas, have them loop between angling further down and further up, basically wiggling down and up from where they are currently.

it is far to exciting see these compete against each other!

Why is this so fun and riveting to watch?!? If you want to do real evolution, you need a 1000 parallel instances executing lots of tests so you can get a true statistical winner, not just "I hope best to 3 is enough!" Maybe a headless scrap mechanic that runs as fast as the engine can process rather than "real time".

The community Sleef Robot fight would be SO much fun to watch

This beginning to become awesome. I hope you continue working on these. Is it possible to add a coloured pinwheel and sensor to the movement checks to add a little randomisation?

Yeah I definitely want to see more of this, MM with everyone making a custom sensor/logic setup on the pre-built base would be great

12:05 You should add there a repeater or some other mechanism which would determine whether to turn right or left in impasse situation. Ie. when the logic gate is on, turn left, when off, turn right and use some system to flip-flop it. You could make a timer which changes it periodically, or a memory bit so that it always turns the other way than previously, or what ever else. Should be relatively easy to implement.

For the next evolution have rear sensors to dect other bots. If they get triggered the bot turns toward the other bot. This could lead to them cutting out other bots just because they're behind them

4:11 I think one of the issues the Blue bots were having is at the very beginning of the video you reduced the Hole Sensor angle slightly which may have caused the Blue bots to not see some of the holes until it was too late for them to turn away. I thought I saw some instances during the matches where the Blue bots seemed to get very close to the edge before turning even with no other bots nearby. Might be worth a retest.

to make it completely fair, you could have four different AI, all spawning on each four sides (so 16 bots), and each side has a different spawn order, in case some variants have slight benefits for being lefter or righter in spawn order. Plus, more AI at a time averages out results better

If you're going to be doing more A:B testing, I'd like to suggest splitting the starts into pairs on opposite sides of the arena. So f.ex team blue starts on the left side, and team red starts on the right. I suspect this would yield much more interesting results, as the robots would start out driving towards each other.

I'm wondering. What about a 9-Grid arena, and then Everyone gets a player and 2 bots to a team!

Repairing spleef where you can use vacuum pumps to repair gaps in the cars board. Or maybe glowbug spleef? You can drop glowbugs down in addition to the guns?

You should double the hole sensors so that when there are holes from both sides the robot will pick this with less" hole" (less double sensors on)

Instead of rotating plateform you could drop the roots from 20 blocks and let them bounce a little to get the initial randomness

I think the reason why the change doesn't seem very positive, is that it's so small, RNG takes over. But not all negative things lead to negative things, sometimes. They can lead to even greater things.

Love this idea of a base spleef bot and having others build off it

are you gonna do Bots v Players once you have the bots trained up?

They kinda look like snails. You should put little shells on their back😊

It looks like you're almost there... just one more wrinkle to iron out... the 'Hole Vision' acts too much like Goose Eyes and sometimes pays dearly for having too little vision exactly straight in front of it. A second pair of 'Hole Vision' Sensors between the outer ones keeping more eye in the front might alleviate this, though I dunno how to go about Logicing this to co-op with the existing 'Hole Sensors'...

"Old Ones" I thought you were talking about eldritch gods there for a sec lmao

What about trying to make a bot that doesn't mistake thin cuts for dangerous holes? Like maybe give it two hole sensors per side in slightly different angles and they both have to deactivate for it to turn.

So, uuhhhh, hey kAN, maybe some slightly longer delays on the rotation for launch pads, cause uh. almost got a swasti there, brother lol

If you provide a chassis for a community challenge, your login should force that the robot can’t just stop, nor just rotate back and forth in place forever.

Think I might know what could be causing the Large Pistons to flicker: The spud guns that remove the starting platforms are still firing the entire time. Either make them stop firing after a timer, or attach them to the starting platforms so that they drop as well.

A lot of your robots falls were from driving directly into a sliver of a hole in front of them where neither left nor right sensors were able to detect it. having a forward central sensor to detect that sort of sliver hole before it gets too close to be able to turn away from them would do a lot to help your bots.

I think a gap ruler instead of binary detection would be good. Check multiple sensors to determine the thickness of a gap. This could allow for decisionmaking contingent on encountering lines, wedges, and the actual edge of the map. Another neat idea is a robot with timers that alternate between various personalities conditionally. My last thought is a networked robot that communicates information to its allies.

Add a hole sensor in the middle to determine if it should go straight or left. You might need two to make sure the platform is wide enough to fit and not bottom out

I have 2 ideas for how you could make the robots a little better: - instead of the robot automatically turning left when it doesn't see anything, make it switch to using sensors that are right in front of the front wheels looking almost directly downwards so it can have more precision to be able to avoid holes, and make it default to going straight if there is nothing below the wheels. - add snail shells to them

one without a default turn would definitely be interesting. When in doubt go straight.

Next upgrade should be having mid front sensor branch or to have the 2 branch pivot less outward which, in this case, I would make the sensor face straight forward on the tire line. The second option is especially good because you actually check if there is a surface for the wheel to go on instead of looking for surrounding holes

21:55 26:55 Blue died to the same shape twice because it couldn't see the hole in front of it, I think they need a hole sensor to the front as well perhaps? 🤔 (It's a fairly common shape due to the way they turn away from holes)

Also kAN, you should add a robot that tries to run into other robots and technically like kamikaze and Pugh itself and the other robot into a hole.

Love the videos you are doing a great job i would love if you could make a new coop on scrap mechanic ❤

Off topic. My wife and I are going to up-grade our GPU's in our PC's. Stay team green, or switch to team red? And thanks KAN for the time to make to shows for us to watch.

If you do set up community events, you could even try making multiple bases for the community to build off off, sort of like battlebot weight classes. Like one is a small electric motor with medium sized wheels, and one is larger wheels with a stronger motor. And even have different sized arenas depending.

You could have a fully randomized starting position instead of the platforms. Simplest, I think, would be to just have some ceiling for everyone to hang of. To randomize them, add 2-3 beams of different length, connected with a rotating bearing at different speeds and directions, with the robots hanging of a cardboard to be shot off 1block above the map. Would need to stop the rotation before starting probably, otherwise there might be some throwing of the robots that can cause issues.

Your hole sensors only detect if there's a hole in the diagonal forward directions. There is a giant 45 deg wedge directly in front of the car that can't be seen. You'd need one more viewing directly forward to prevent the bots from driving straight into a hole like blue disappointingly did 2-3 times.

You should have one with a sensor in the middle so if it sees a hole in both sides but a path infront it will keep going straight.

I thought of spleef games using both players and AI robots as well using some past spleef mechanics. The idea is the vehicle itself is robot controlled on its route once launched, however players can themselves control the angle of the starting point of their perspective robots allowing players to start in the direction they want to go to at start of game. Players can also mess with priority code to drones personality. Robot sputter gun under robots rear doesn't leave clean cuts but checkered like pattern. Players don't control robots path once game started. The players instead control different tools of robots such as the player sitting in a turret that shoots potatoes I believe the scrap mechanic uses Players also have the ability to drop an explosive or two every once and a while. Players also control a crane arm that rotation is full 360 with a sputter gun that doesn't make clean cuts but again checkered cuts. And any other tool a spleef vehicle can have it has it for players to manipulate. Also for last resort move left mechanic what if the drone randomized prioritizing left or right turns A game of AI and players working together

For MM you should play spleef on the top of the map while the robots play upside down on the other side!

One of the most important first steps for improving would be for you to not waste so much space with redundant or pointless logic gates. You can remove like 6 logic gates from your thing atleast (i wasn't really counting) but its understandable you're more a mech engineer than a electrical engineer But definitely with cleaner logic than you can very easily add logic where it goes forward if theres a hole on both sides would be best if there were 3 hole sensors instead of 2, it can't actually see holes infront of it, which is why it struggles to avoid holes that aren't the edge of the map

I think you screwed over the blues by reducing their hole sensor angle. I don't think they could see the holes as well as the v1 bots

Add a personality where when it detects holes or robots on either side it will randomly choose whether to turn left or right instead of auto turning left

once you find the "perfect" robot, you should see if they can beat your friends

How about have one variation that is like this new one, except it doesn't just avoid holes, but also tries to keep a fixed distance to any hole or cut it detects on either side, moving parallel to any existing cuts; except when it sees a bot on an 180 degrees arc behind it it will switch to cutting thru the the closest line (but not full on hole as that would be suicide) in a wide S pattern to try to drop any bots trailing them?

I think you will need another set of forward sensors to look for holes angled between 10 and 20 degrees that are 1 lower priority than the ones you have now to see holes directly in front of them.

Hang the robots above the arena like a baby's mobile where you spin the arms, and the cars individually. You just have to move it to the side and disconnect it to not obscure the view when they're dropped

Perhaps you could add another pair of hole detecting sensors to the front so that traingle shaped holes don't kill them as easily.

love how the title makes it sound like hes fighting the old gods

Put the hole sensors on alternating pistons for a bit of rng movement and to give them the ability to see holes a bit more ahead of them.

i think them being on the same side makes it more intresting, that and maybe have sensors to see if the robots are still on the platform before they drop the start platform may prevent them from getting dropped, and or pistons to pish them off so they dont get stuck maybe? its been years since ive played so idk if the friction or something will hate that but its worth a shot :D also maybe you can have a seat angled downwards on some pistons in the middle so you can view them easier without the glasses light glare

Add a support for the center to prevent them from getting cut out

Can you do Spleef but the vehicles travel faster? I think it'd be interesting having less time to think & react. But I wonder if the guns wouldn't cut so cleanly through the cardboard, so you'd have only scattered holes, take forever to actually cut anything out.

I recon it would be nice to have them randomly decide to turn and such when there is nothing else going on so they don't just drive straight

8:40 you think your brain was lacking power? My brain's been lacking power ever since I was dropped on my head 15 times as a baby. 😅😅

I think having the starting platforms 2 and 2 at 90 degrees all with the ramp things, would be better. That way they would be more likely to meat somewhere in the middle, I think, instead of almost always meeting at the other end of the arena

I'm frequently astounded at how creative you guys are. I am intellectually stuck on children's alphabet blocks compared to your guyses designs.
