Lets fix the problem with the weapon bearing coming out. Put the bearing in an aluminum holder that maintains dimensions, and put that against the plastic to keep the same degree of shock mounting.
The bearing is held in with M4 flanged button screws. Eight of them.
It slots into the frame.
|The robot uses the same dimension blades as before.|
Finally, this robot uses 12 mm brushless motors connected to Silver Spark 22:1 gearboxes for the drive. To control them, I made my own triple brushless control board. It's based on the STM32F3 and Allegro A4960. It was squirrelly and hard to drive, despite gyro correction in the controller.
