The car runs at 25 MPH for about 20 minutes on a
standard set of two 7.2V battery packs. We will equip the beobots with
four packs and several Nickel Cadmium camcorder batteries to power the
on-board quad-CPU Beowulf.
The Motherboards
The Beobot needs a power conversion system to convert
the battery power supply to voltages and currents suitable for our
Beobot computer. We did a schematic diagram and a printed circuit
board layout using the freeware version of Eagle PCB software from Cadsoft.
The
final version of our infernal power conversion system is ready for
fabrication. The circuit just fits within the 3x4 in maximum board
size available in the freeware vesion of Eagle PCB.
