Building Red Reaper: My Combat Robot from Design to Testing

[@TeamJunkYardDog]

I have been fighting horizontals since 2018. The only weak point I see is weapon attachment to the pulley. The heat inserts will rip out very quickly in combat. Especially from a vertical spinner hit. I bolt all the way through the pulley wit a T-Nut on the other side. If your main pulley is printed you need at least 6 layers on the walls or the center of the pulley will explode after vertical hits. Beautiful design and I look forward to seeing the battles! Good Luck!

Agreed, this was the first thing I picked up on as well, heat set inserts just aren't good for strength and through bolting is way superior

Nice combat robot. Looking forward to seeing it do well in the competition. Stay safe.

im planning on building one kind of like this but my only concern is the pulley In the last fight I saw almost every robot with a horizontal spinner lost because their weapon broke specifically the pulley broke any tips so I can avoid this problem maybe a metal chain could work? w

Good luck building your robot! You could try to add some kind of protection to the pulley that is attached to the frame or maybe use 2 belts. I don't think a metal chain will work for the speeds you want to spinn your weapon.
