Sloth is my 30lb horizontal bar spinner which competes at the Robot Riots and NERC events. Sloth is almost complete!
12" Supernaut blade on for show.
Sloth is a 4wd 30lb bar spinner. It uses 4 18volt Harbor Freight drills @ 24v for drive on 3" wheels, with cncbotparts hubs. The drive is controlled by 2 victor 883s, 1 per side.
The weapon is a 24" 3.5lb tool steel bar which spins just under 3" from the ground. The weapon motor is an ev warrior
which is run @24volts. There is a 3.5:1 belt drive from the motor to the blade. The weapon is controlled by a RCE220 with an 80amp relay.
All is powered by a 24v 3000mah nimh Battle Pack. The frame is 1/2" 6061 t6 aluminum pocketed to 1/4" to save weight. The control system is an Airtronics VG400 FM radio.
