We built the 250 lb combat robot Switchback for the latest season of BattleBots (2022) with a team of 11 engineers. With an 80 lb drum spinner on the end of a 180 degree articulating arm, Switchback is full of engineering challenges. And we had only 3 months to get it working…

From my experience at BB my advice to new builders is don’t build your first combat robot trying to do things the “new way” brushless drive is far less reliable (but sometimes necessary due to space constraints). Also the Battlebots floor is really difficult to get good traction on so small, hard, smooth wheels are usually not the best choice if you have a high center of mass. With all that being said, tremendous props to this team and what they accomplished. I’m sure they learned all of those lessons before they even left the event. I love this video and the bot is a really neat concept and I’m sure they’ll be back even better next season!
@wrlprchnx Рік тому
I'm going to guess that with brushless motors you end up blowing up the controller boards pretty frequently... my experience with eletronic controllers is that they aren't particularly fond of vibration - getting sufficient isolation for the board so that it works reliably in competiton must be terribly difficult.
@rickhunt3183 Рік тому
@@wrlprchnx I've never examined a failed speed controller board to determine cause of failure, however I would guess heat buildup due to large current demands and insufficient cooling would be the main causes of failure. Vibration failure can easily be overcome using polyethylene or a polymer resin to encase the parts so the components and circuit boards can't flex. Once that's done the components will be held rigidly in place. Heat dissipation will be your primary concern after that. The only method I know would be to used a water cooled heatsink that's also encased in the polymer resin making direct contact with the FETS using thermal epoxy. I'd consider using a couple of negative coefficient temperature sensors connected to a ESP-8266 to monitor temperature and control the cooling to critical components. Just my thoughts. Maybe you have alternative solutions you're considering.

the vescs getting destroyed is a very common issue, try this: Solder a 50V TVS diode directly onto the pcb. Adding a low ESR cap also helps but that will increase bulk a lot. The vescs dying usually happen because of voltage spikes, tvs diodes and caps help with that a lot!

I was thinking the same thing, this bot looks too simple electronically to handle well. battle bot have been too concentrated in getting good mechanical design, but good electronics, sensors and microcontrollers is also really helpful in controlling. I wonder why few ever go past using simple RC parts, even a flight controller will help with stabilization
@gchampi2 Рік тому
@@yuxuanhuang3523 I think the sheer amount of power being pumped through the systems may limit the complexity of the control systems. One of the other robots this year blew up 3 ESC's in their weapon setup, and had to revert to a spare that was only rated for 50amps. It took their spin up time out to 15s instead of the 3s they were used to from the (IIRC) 300amp setup they had grenaded. There are many reasons to stick with proven "dumb" systems, including ease of setup, ease of troubleshooting, peak current capability, reliability, ability to survive the combat environment, and overall cost. More complex systems tend to cost more, and add more failure points - and if a system can't survive being hit with a flamethrower, having a 100lb steel bar spinning at 250mph slammed into it, or being dropped from 12 feet up onto a floor made of 1/2" steel, potentially all at the same time, then the average roboteer won't use it.

@antagonizerr Рік тому
Hey here's something that no bot builder has thought of. Installing limited slip clutches on their weapons and arms. I built recycling plants that wash tank paddles would jam up under excess waste material. to fix this, I added spring loaded clutch plates to the motor so that it would spin under power, but if the counter force was too much, the clutch plates would slip saving a lot of chains and sprockets. Your weapon stops abruptly on contact. A limited slip clutch would prevent it from burning out from excess load.
@bldjln3158 Рік тому
Believe it or not, clutches have been used since the very beginning of robot combat. Anything beneficial that you can readily think of has been done already. Especially something as simple as a clutch.
@antagonizerr Рік тому
@@bldjln3158 I've watched every build vid from Blip to sawblaze and not one has incorporated a clutch.

@tristanheartt2272 Рік тому
cool idea, but there are a few problems: 1. That works with projectiles and things that can be slowed down. Since the weapons are almost as big as the whole robot, they aren't going to slow down from a bit of soft material. The AR500 will do all the work when it comes to absorbing impact. 2. The judges use visual damage as a metric when the game goes the whole time. Chunks of aluminum and plastic are bad news in a close fight.

"The resistance was infinite so essentially a dead short" That is 2 completely opposite states of resistance, not remotely the same. High resistance is the exact opposite of a short.
@Amy_A. Рік тому
I think what he meant was that the controller had to crank up the output to overcome the resistance, and that increased current output made the controller act similar to a dead short scenario. They clearly at least *somewhat* know what they're doing, so I'll give em the benefit of the doubt here.
@yuxuanhuang3523 Рік тому
@@Amy_A. I have another explanation. It is a three-phase motor, and when one cable is not connected properly, the motor will not spin because two cables connect through one coil. What might have happened was that one connected coil was acting as a short because it was passing DC current. What should have happened in a spinning motor was AC passing through all three coil at 120 degree apart phases.
