Building combat robots can be dangerous. The robots themselves, particularly those with spinning kinetic energy storing weapons, are extremely destructive and powerful. They tend to easily lose control or experience rapid unscheduled disassembly, both in testing and during a fight. The best way to prevent injury or death is to always safely test robots that have spinning weapons inside an enclosure which completely eliminates a direct line of sight between the robot's spinning weapon, and any nearby soft fleshy humans. There are other ways to test safely, but a test box or arena is generally accepted as the safest. You can build this box for under $80 USD, which I am told is a lot less than the medical bills to replace a missing finger or eyeball.
I am not claiming that my particular test box design is the 'best' or only solution that provides this level of safety, but having used it for over a year with robots that store as much kinetic energy as a fired 357 magnum round, and having said robots ram their spinners full force into the floor, walls and ceiling many times, I'm confident it will keep me safe.
Given the recent rash of unsafe testing videos, and the fact that my last safety video was uploaded over a year ago to just 100 or so subscribers, I feel this topic is in need of a redux.

*Sees this vid* *Vietnam flashbacks* Whats interesting is that having one of those incidents where a steel bar goes flying across a garage promptly made me an extreme advocate of safety. Good vid, thanks for the info!

My man built a robot that plays Take On Me by Aha! When he turns it on. Just for that you deserve an award. (Edit) Also, ALWAYS be safe when handling robots y’all. A 150g lifter bot nearly crushed and broke my finger when I was being a bit irresponsible upon turning it off after a match. If my finger had been any further inside that robot, it would have snapped it like a chopstick. So even the smallest of robots can be dangerous.

It's like your read my mind. Was looking at different test box builds for my 150g to 3lb, and there here you go. I'm for sure using the clamps you used great way to keep box locked. Again great video and cant wait to see more. PS where the mulcher?

@mrbk5916 3 жыл бұрын

honestly this was a pretty good video going into detail of your test boxes and the process of loading and ariming stuff in your testbox and going to be fair for 150g robots you can easily use a draw from a old tv stand or a dresser with a 10mm polycarb top and a thicker base attached to the bottom around 5-8mm would work depending on the type of wood

I wouldn't consider this to be an arena per se, visibility is poor from the sides. However... Here's a sneak peek at a project I have had in progress for a while now. bit.ly/JustCuzAntArenaFiles

If anybody's in any doubt about what can happen when spinning things meet meat, have a look at the latest video on Andrew Newton's KZfaq channel. ('CADDX Nebula Pro Vista Kit'.) Andrew's an enormously experienced RC model aircraft enthusiast. He recently had an accident when his hand was cut by an electric motor spinning a plastic propeller. (Similar to the kind of thing used on a quad-copter.) His hand was badly chopped up and needed hospital treatment (yep, actual surgery). Very messy and extremely painful. Bear in mind that this was a small brushless motor turning a plastic prop weighing just a few grams. A robot's kinetic weapon is made from tool steel and is designed to cut metal, so tangling with one will be worse than sticking your hand in a blender. (Worse because a robot leaps about unpredictably after the initial impact.) A bot like Division could easily shatter bones and amputate fingers. A heavyweight bot like Bloodsport could (literally) kill you. Let's be careful out there...

Great video, hopefully it helps folks realize it’s not that costly or challenging a build and more people will make one. Why do you have the transmitter on when you put your bot in? I’ve never wanted my hand anywhere near the weapon with the transmitter on in case the transmitter gets bumped or something.

@JustCuzRobotics 3 жыл бұрын

There are arguments both for and against this. Keeping the transmitter on during load in with the transmitter resting flat on a table away from any bump-happy hands is the way the Battlebots safety team requires it during load in. It's recommended by several other competitions one been to as well. It is generally just a safeguard against a robot doing things you wouldn't expect when its receiver is getting no signal. This is very rare with modern radio equipment but you never know. And if failsafes are not set properly, powering on the bot without the radio on can make it do dangerous things. I also feel uncomfortable about possibly bumping the radio which is why I have an arming switch set up as I described/showed and programmed my radio to require the switch is in the disarmed position before it will connect to the bot's receiver on startup.

you are scared of beetleweights? my team tests 60kg robots 3 feet away from the driver and with no testbox in a collage classroom with benches and 12 more people in the room.

Whether you're scared or not doesn't change the fact it would easily kill you or rip your arm off. That's like saying ' "I play with loaded guns with 12 people in the room in a college classroom!" Congrats on being horrendously irresponsible. Just because they haven't hurt you yet doesn't change the fact that they easily can or will.

@@JustCuzRobotics the point is that in india the arenas are really unsafe. Sometimes 60kg category is driven on concrete and 2 cm thick bulletproof glass is used for walls and metal mesh to cover the top. And being the whayachis of india, the people being present during testing are not scared.

@@JustCuzRobotics every single team reports an unsafe arena. And the quality is little improved but if it is still unsafe we bring in 2 wedge botz and destroy the walls of the arena. By ramming into them, there would be no audience during that. So literally the event is cancelled then.
