This is the easiest part as most chassis components were purchased from Jaycar in a kit form. The kit comes from Tamiya and comprises of 3 parts.

1. Universal Plate Set - No.98
2. Track & Wheel Set - No.100
3. Double Gearbox - No.168

The chassis is very easy to assemble. The gearbox comes with two 3V hobby motors and you can configure it with 4 different gear reductions. I settled for 114:1 step down for two main reasons, I don't want the robot to travel too fast and it needs to have enough torque to carry all the gear on top of it. The main wheight will be the battery. I haven't decided what type of battery to use yet but it must be rechargable and last a long while.
