Decided it would be easier and cheaper to make a 6 wheeled UGV with high torque servos. These servos cost $4 each and are pretty decent for they're price from HobbyKing. The servos i used had a 6kg pull. I just had to make 6 of these for the drive train.
I used 12mm by 12mm (1mm thick) aluminum angle brackets for a mounting bracket for the servos. The brackets are 4cm in lengths for each side so i had to make 12 of these. The servos are exactly 2cm in length so i centered it with 1cm clearance on each side. The holes for the suspension shaft were centered in by measuring on the other surface, 1cm from each side and creating a cross by drawing lines from each corner.
Each wish bone was 8cm in lengths using 12mm by 1 meter by 3mm flat aluminum. I had to cut 24 of these. The holes were center by drawing a line right angle to the longer edge 1cm in. Then drawing lines from each corner creating a cross in which you drilled the hole in the center. For the suspension action to work you have to file (AFTER DRILLING THE HOLES) each corner so it is round.
Great writeup!
