You put a wheel on each corner, but only 2 are driven.

look at this here robot wot I built...

it shows the layout of the wheels, and the attachment.. obviously this is a sumo bot, so its ok to use old bits of pneumatic pipe as axles.. I suggest for fighting at 12kg you use something a bit tougher.. but the principle is the same

just a few of suggestions based on the chassis as it was when you got it....

1- golds are too big, youd need to increase the height. means modifying the chassis shape.

2- 900s, bigger than drill motors and you still need gearboxes, so youll need to make or buy a gearbox, and they stll wont fit inside the chassis without wheels outside.

3 - just use 4 cheap drill motors with external wheels, and add 10mm polycarb sides to enclose them. You will need to cut these polycarb bits, and some bolt on brackets, but thats easy enough. I recommend this option.

sorry to pinch this thread but i am looking at drive for a featherweight and i would like to buy either mini ev motors or hti motors the hti motors i would gear at around 1:1.5 and im not sure wat i would gear the mini ev motors to. would you agree with this or do you think that these motors will not be powerful enuf (i would go for golds but these work out cheaper even with postage from the states and i dont have the 50 pound for golds)

thanx,
josh

If you are still building this robot, email me and I will send you some pics of one that I built for my grandson using one of Jamess pay to drive shells. Using two cheap Do it All drills and the batteries.

Pic now on profile.

it was nice to see good old toxic rebuilt as a fighting robot Dave. you did a great job.
