Ever wonder what’s under the hood with a competitive battle robot like this one? It’s usually a big secret as teams don’t care to give their competition any help. But [AlexHrn] decided not only to give us a peek, but also shows us his step-by-step build process for Phoenix, the 30 pound flipping battle robot.
[Alex] has already seen quite a bit of success with a different robot, but he couldn’t quite beat another competitor whose bot included a flipping arm which threw its competition across the ring. So [Alex] decided to join in on the technique with this build. The arm itself uses air pressure to exert a large force very quickly. Inside, a paintball gun tank powers the pneumatic ram. It looks like this tank is charged up before the competition and only gets about 12 shots before it’s depleted. You can see the power in the quick clip after the break.
For locomotion the unit uses a couple of cordless drill motors. These have a fairly high RPM and work well when powered by batteries.
