Design Concept

4 Scooter Wheels:

Stability
Turn Radius: 35"
Front Wheels: 12" diameter
Rear Wheels: 12.5" diameter

25H Chains

Front: 1 chain connected to the step motor
Rear: 2 chains connected to each rear wheel and motor

Front Wheels:12” Rubber /Alloy Rim
Step Motor /Driver
3.2V Batteries
25H Chains
60V ESC
2500W Motors
Rear Wheels : 12 ½” Rubber

Overall Description

The battery will power the motors, voltage converter, raspberry pi, arduino mega, and the electronic speed controller (ESC).

The raspberry pi will be used to communicate with the Comprehensive Open-Architecture Solution for Mission Operations System (COSMOS). The arduino mega will be used to communicate with the ground station.

This configuration is based off a rear wheel drive, where the front wheels is steered using a small DC motor and the back wheels is powered by 2 DC motors controlled from the ESC.
