This was filmed during the 2021 lockdown when a travel radius limitation was introduced to reduce spread. That's why it wasn't appropriate to travel to and film at the beach. They are no longer in effect.

The reason it's loud is because of gearing. They use small DC motors and a plastic spur gearbox. I love the look and scale of it. I wouldn't mind getting my hands on a cad drawing of one.

The fact that OwObotics is a thing is proof that we are evolving

Next round: RCTestFlight's 3D printed tank/snowkat

Every episode, I enjoy this series even more! I can't wait to see how well those gears survived.

When I saw the spiked wheels continue to drive while upside-down, it reminded me of a demo of police robots that I saw a few years ago. They had one, not much larger than your platform, that was made to be tossed into a building. It didn't matter how it landed - it could drive either way.

I know you might think you're a pretty boring person but not everybody can make playing with remote control cars fun to watch 😆 I love your videos man, thanks 😁

Foliage Fortress? Tiles of Trepidation? Dodo?? Bro you are the Best 😎!! This is srsly awesome!!

While I know you probably don't want to spend dozens of hours printing various wheels, but I'd love to see more viewer designs put to the test. :) I bet there'd be some really fascinating designs to overcome the traction, even using slick PLA.

Hi, There is this stuff where you can "rubberize(?)" your metal tools so they have a rubber grip, what if you put that on the edge of the wheels to give them some grip?

There's something very cute about this, like DARPA showing a combat robot being tested on a children's climbing frame because of lockdown

Ngl I was giggling seeing the concept of my wheel's design performing so well. Downside - damn slippery TPU. Really appreciate the ego inflation going on there. Also damn sorry my design embued your rover with my slightly pervy sense of humor.

An awesome sequel series to this would be a custom track design contest, seeing how much better the base model is compared to wheels.

Why not to create your own tracks you could mount on the spike wheels? Good fun!

I'm glad you got to have some fun during your lockdown, cheers for the vid

This was a really fun video to watch, you did a great job designing the course despite it's simplicity.

Loved the Backyard course. Great memories.. Thanks

I like these hobby meshing videos. It’s cool seeing fresh ideas for projects that might be obvious to some, but others may not have ever considered.

No matter what many people think, military designers are not stupid and there was a reason why tracked vehicles were adopted due to there offroad capabilities. No type of wheel can ever come close.

I love the work you are doing on this platform. Keep it up!

Crazy tracks next?!?!? Love this series!

Really enjoy the channel btw. You convinced me to get into 3d printing as a hobby :)

the alliteration in this video is top teir

Really enjoyed the tests. Thanks so much for putting it all together.

I love the random obstacle course! Just the stuff around Angus home. It always a good day with a Makers Muse video!

Excited for the next set of wheels! The obstacle course is perfect for your robotic platform and the crazy wheels!

The Tank running the course reminds reminds me of the obstacles in commercials for Tyco's offroad RC toys.

I love this series! Fun to see some robots and 3D Printed projects together.

A lot of fun watching too - thanks a lot!

Reminds me of the old Tyco Rebound. Its a bit silly but I'd rotate the axles outward and stick some 2.8 monster truck wheels on if the gearing doesnt burn out the motor and allow it to run upside down like the Rebound

Angus is such a cool guy. Would love to have him as a friend (one that you don't see much but you always get hyped when you going to meet)

Did anyone else get a "young kid in backyard, playing make-believe" with the obstacle course? Fun video and great finding a solution to "can't leave home"

This is like a video-paper on "Wheel profiles for home-garden exploring robots". The same obstacles would be found on my parent's garden xD

Great series. I love rc cars and that is what got me into 3D printing a couple years ago.

16:00 To be fair to our Dodo friend, he shrugged off that hit pretty well 🤔

Innovative use of lockdown, Angus. I don't expect anything less from you. Very interesting physics with mundane objects 👏

I made a tank out of ABS, everything is printed solid at 98% infill, it has metal-toothed pullies as you find in a 3D printer with toothed belts as the reduction drive with 2 quadcopter motors. It has double reduction (i.e 2 belts per motor 1:16 reduction ratio) onto a metal shaft, a long bolt, using the hex bolt head to mesh with the ABS drive wheels (sprockets). The other only metal part is the roller bearings used on the main drive shafts and on all idler wheels. The shafts for the idler wheels are printed in ABS and 4mm in diameter with a slight flat on one side so it is printable. The idea works really well and is really strong. The shafts are stationary with the wheels spinning around them. Everything else is ABS printed (apart from screws and nuts holding the various parts together). There are 2 ECU's to drive the quadcopter brushless motors and the ECU's are controlled by an Arduino nano fully programmed by me (no Arduino libraries except for the NRF24L01 library). I find that printing things flat and bolting them together gives really good strength. It's a bit like cutting it out of plywood or a sheet of metal. The tracks are printed in ABS using nylon 3D printer filament as pins to hold them together. The quadcopter motors cost about $15 AUD each and the ECU's cost about $20 AUD each. The ECU's were reflashed with Simon K software to give forwards and reverse on the motors. The Arduino nano cost about $4 AUD and the NRF24L01 cost about $4 AUD. But I used a whole roll of ABS at about $35 AUD. Many parts were printed several times with minor tweaks to the design. I also made a bulldozer with a NEMA 17 stepper motor in the track frame and a single reduction belt drive (1:4 ratio). The motor has a metal pully (from a 3D printer) with a toothed belt but the sprocket end is printed in ABS with both the large-toothed pully and track drive sprocket as one unit (contained within the width of the track) this meant I could use a stationary shaft printed from ABS just like on the idler wheels. The belt is inside the track frame. By mirroring the process for the other side I had two tracks (no drive motors within the body) with wires from the track frame into the body. This gave me room to put a 3rd NEMA 17 inside the body to raise and lower a blade on the front. Again I used an Arduino nano to control all 3 stepper motors using my own code (no Arduino libraries except for the NRF24L01 library). The NEMA 17 's cost about $4 AUD each and each NEMA 17 has a stepper controller board (DRV8825) I also used voltage step-up boards to step the drive motor voltage up to 26 volts. This lets me run the NEMA 17 at 1,100 RPM for a somewhat slow top speed, but hey, it's a bulldozer and they are slow. I built a remote control (from ABS) using an Arduino nano with an NRF24L01 wireless board with a screw-on antenna. I used hall effect sensors to read the joystick movements. The remote has automatic trimming on every axis (two joysticks with 2 axes each). Both the tank and bulldozer is steered by only one joystick (forwards and backward, clockwise and anti-clockwise turns). The bulldozer uses the second joystick to raise and lower the blade. Both the tank and bulldozer use NRF24L01 wireless boards with the antenna "printed" on the circuit board, to be controlled by my homemade remote. If only I could post photos!

Incredible video!!! Keep up the awesome content!

Has anyone else realised that Angus looks really fit? Like how do you do it man? Looking quite snazzy in those shades btw Also I really enjoyed watching the video :D The names of the obstacles in the course show how much you think these things out haha

Someone may have already suggested. What about create a gear and idler wheel for the new platform and print tracks and see how the new platform behaves against the tank?

So much fun to watch!

Excellent project

Some years ago, there was a huge debate in Canada about whether we needed true tanks for our army, or could do the job with light armoured vehicles. LAVs are not only cheaper to purchase, they're easier and cheaper to operate because they have wheels. In the end, experience in Afghanistan convinced the government there was still a need for track-laying armoured vehicles. The bit with the EAT06 reminds me a lot of the videos being passed around by the pro-tank side. :)

Looking forward to the next vid in this series! :)

This is both fun and informative!!

Best Spectator Ever! Would love to see some tracks printed in TPU and hard plastic with different treads. Maybe some sort of interchangeable bits?

I like how the tank demolishes the course but then gets demolished by the Dodo bird.

Great job making the best of the situation with lockdown

I would totally watch any sort of robotics/printed vehicles/mechanics olympics on this channel similar to the marble olympics.

This was a fun video to watch, but then so are all you videos. Each video you release I learn something and have fun. Thanks for teaching a 54 year old dog new tricks. LOL :)

Awesome video. Keep on living your dreams. Regards from South Africa 🇿🇦

Hey great video, thanks a lot. I look forward to seeing your design and building my own, I see a lot og great projects in the future.

This was so much fun to watch

Thanks for some great lockdown entertainment

this is some really entertaining stuff, love all the wheels

Love the fact that the motors names starts with OwO

I love seeing how all the wheels preform

V1: low fast fairly simple V2: more ground clearance, better motors, gear box V3: suspension, monster truck tires V4: tracks without suspension V5: half track with suspension on the tires and tracks with all previous aforementioned upgrades. V6: some sort of system to allow for vertical movement like a grappling hook launcher

Great video! I was just watching the difference between a drill and an impact driver and the spiky wheels seem like an impact driver.

VIDEO IDEA: 1. Make your own tank tracks out of 3D print to be used on your RC platform. 2. Try alternate track systems. Like your multiple versions of wheels

This made me laugh a few times, which is quite the accomplishment. Thanks!

The wobbly wheels being good on rollers kinda makes sense. Because they aren't just pushing in line with the platform, they are also acting kinda like a with a screw action where they are pushing sideways as well which moves it forwards

The fact that you live in Australia and didn't call the video '' crazy wheels VS my outback'' astonishes me

Wow, that a Rundown.. Thanks for sharing :-)

I can see this becoming the Fan Showdown of Max's channel

Please make this into series where your subscribers design the wheels and you test them just like that guy with pc fans

love the orange glasses

The 2021 Summer Olympics have nothing on this. Speed, performance and stamina and possible sabotage with banana leaves. The encounter with the garden hose is what lifted it to achieve Gold.

Very "Legends of the Hidden Temple" with the course. Love it.

Quite fun to watch :) If indeed your gears got damaged you can use helical gears next time. With more teeth in contact at any time they can handle higher torque. With 3D-printing even double helical gears are easy to manufacture. That way you don't even get axial forces as a tradeoff.

Tbh if you made the platform higher so that the wheels extended down that would help

0:50 "OwObotics" Angus: "UwUbotics"

I feel like those flexible wheels would work really well on a fast RC like an Armma Granite or Traxxas of some sort. Love these experiments!

man top notch obstacle naming!!

It would be interesting to see the wobble wheels with a soft, sticky rubber tire. The combination of traction with eccentric motion might be very effective.

Bruce, my cat, loved this video.

If you used a spray rubber coating on some of the smooth plastic wheels, I'd be interested in the results. Might give more tractions. Another idea - wheels with variable but even width. Would allow you to climb narrower surfaces that are above and below and drag the cart towards the grip

Such a fun video to watch, hope to see more spike type wheels in the future!

Please Angus, has the RC bumping the dodo had some babies together??? 🤣

How did you record that outdoor voice audio so clearly, that was really impressive

I love your videos!

This car with the wobbly wheels looks like a drunk turtle trying to complete the obstacle course.

This was cool muse

"live from Bored during lockdown, Angus presents ..." nice one!

Very cool video.

Pretty cool

I love your channel Angus. I am blown away with your creativity. I just cannot fathom why you do not have a cheap wireless lav mic. Like even with Australian rubles it cant be more than a few bucks. I am talking about the cheap knockoff Chinese Rode lapel mics. I have like 3 of them that sound amazing and are small enough to wear on a t-shirt without an attached lav mic, but just wearing the box part. Anyway hope its not too harsh. I offer it as a kindness and not to be an asshole.

Looks like the brushless motors struggle at low rpm. That's just super hard to avoid with sensorless comutation. Also, try adding a v-tail mixer and tail-rotor gyro to the platform. I'll transform you into a drift master and MASSIVELY increase control.

4:00 I love how the tiles perfectly match the wheelbase of the car, so it kinda bounces across

I’m glad you reset and tried again sometimes. Even with real off-roading while really having the proper setup for the terrain, it doesn’t always go perfect the first time and you have to try again. I always hate when people “testing” something are so rigid and rushing so much, that they give something 1 try and if it doesn’t work, declare it a failure even though it may have been their control that was the problem and not the thing they were testing.

Great names for the obstacles! 🤣

I hope you’re doing good in this dang lockdown

lol love the glasses. 👍

Lockdown is the mother of desperation Angus. Nice job.

You could try mixing types of wheels for improved performance, eg. one type on front other on back..

You said our bananas.. but I heard I'll be honest... I thought you were talking about the birds not being ripe enough, and thought it was hilarious. Like ooh, spectators!! They taste delicious though

I like that ripsaw tank

This was a balm for the inner child. :D

Your notification makes my day.

Future idea: Using your custom design, some large toothed wheels that are taller than the body to allow for inverted driving + tracks connecting front and rear. Maybe even with additional rollers in the centre region so that the side profile of the tracks is a squished hexagon.. sort of like how the side profile of the cheap tank looks but on both top and bottom. Apart from the difficulty of turning on the spot (should be overcome by the more powerful motors you have on that platform) I reckon it could drive over damn near anything
