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.
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.
|The robot uses the same dimension blades as before.|
|I'm not perfect.|
It then competed at Dragoncon 2015, winning first place, and a local event SLAW, also winning first place. Post event pictures follow.
|Evidence of the blade pushed into the frame, but this is anticipated.|
|Tip is a little worn.|
|I fought a robot with large wheels that could crawl over this robot (though that's not hard). It was equipped with a vertical bar that hit from above.|
|A few knicks in the back.|
|Went face to face with a drum. Not bad.|
|The brushless motors run super hot. To solve this, I bought thick heat conductive padding for the motors. It worked great, even though the conductive padding is more rigid than the standard polyurethane rubber.|
|Brushless motors stuck on a silver spark.|
|Pinion appears alright?|
|I actually go on to use this hub on quite a few other bots.|
