TO THE PROJECT

Chassis and drive mount

This is the start of the chassis. It is composed of 30mm by 30mm by 3mm by 1m angle bracket.

The longer side is 300mm long and the shorter side is 100mm long. As you can see, my chassis is imperfect but it will have to do for now.

This is an example of the drive train mount. Its it the exact same to the mounting brackets for the servos but the placing of the holes for attaching it to the chassis can vary. As you can see my holes for attaching it to the chassis is in the middle, If you are choosing that the drive mounts should be down low like mine(in case you build my design) don't make the holes in the middle but up high as possible unless you modify the configurations.

This is what the drive train and suspension setup should look like in the early stages, 2 down 4 to go. 

servo mounts and wish bones

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.
