Base

The motors and battery are installed using brackets and supports cut from aluminium channels and angles. The battery is a 6 volt 10 amp hour sealed lead acid battery maintained by an on board charging circuit based on the UC3906 integrated circuit from Texas Instruments. The motors are Hitech HS815 Sail Winch servos modified for continuous rotation. Hobby servo motors don't get much more powerful than these. The wheels are directly bolted to the servo splines, which is ok so long as the robot is not carrying a load. This will have to be upgraded to a chain drive in the near future.
