r.c. snowbot

This is a r.c. controlled snow bot. I used 1/4" thick 5052 aluminum plate for the housing, which measures 24" x 24" x 12". The tracks, sprocket wheels, shafts and bearing housings are from a used Craftsman snowblower. The 4 drive motors are used 12/24 volt wheelchair motors with hubs. The 48" snowplow uses a seat tilt actuator for the up/down movement, and a leg lift actuator for the side to side movement. The blade angle can be adjusted by moving the top aluminum bar. To make this a little more versatile, I mounted a seat tilt housing and actuator on top, which lets me mount a wheelbarrow tray which tilts to about 70 degrees. To make it a little more fun, I can swap out the wheel barrow tray for a bar stool so I can ride it. I used a Sabertooth 2x60 esc for the track motors, and a Sabertooth 2x25 esc for the plow/tilt actuators. Using a dpdt switch between one channel of the 2x25 esc allows me to switch between the plow and tilt actuators. Power is supplied by 4 12v 35ah batteries wired in series and parallel to supply 24v to both esc's. A battery charger is also mounted inside the box with a a.c. plug on the side. The control panel has 2 battery cut off switches, one for the tracks, and the other for the plow/tilt actuators. A dual volt meter is used to monitor the power consumption. Did a few changes. Switched to 2 motors and added another pair of batteries, now totaling 6. Also raised the ride height to get 5" of ground clearance. This involved converting to a chain drive system.
