3DAD Antweight (1lb) Combat Robot

thingiverse

I completely revamped the body to make it even more robust and capable. The bot still relies on a brushless 2204 motor, but I think a 2205 will also work well. I still have some fine-tuning to do on the weapon holder to help it spin smoother, but it works perfectly so far. The drive system is similar to my other fairyweight bots, using small motors instead of the servos in my original Amazon Home Depot bot.

Screw the motor onto the body. Press fit the motor mount onto the motor. Cut the 20 gauge strap to size and epoxy it to the top of the slanted edge as shown. I also included an on-off switch that was hot glued on the bottom of the bot to be easily accessible. I simply took one of the switches from the ESCs.
