I was a bit concerned about the weight of the gel cell batteries above the castor wheel. As it turned out , the performance of this design exceeded my expectations. The design is a true three wheeler. The castor at the back is of quite a high quality which I am sure is really necessary.

This design evolved after a lot of experiments done with the original MACH 2001 which had a few flaws as far as traction was concerned and an oversized controller , the 386DX40 Computer.

The relay driver board used to isolate the PIC16F84

This is the same board used in the original MACH 2001 but is mounted in a different place. The board is placed between the PIC Micro controller board and the automotive relays used to switch the wiper motors.
