This project showcases the rebuild of the AutoKrawlers, two rovers I've worked on as a part of my Master's in Robotic Systems Development work. While doing my masters I faced a lot of issues with the electronics being unorganized, hard to reach, and in some cases unsafe because of their positioning and wiring. This project seeks to remedy that issue for future students and researchers working on the platforms. Pictured above is the final result. Pictured below is the removable covering when removed. showing the accessible components.

Above shows how easily the upper decks can be removed, all while the rover is still turned on and functioning. This makes the motor drivers and low level hardware easily accessible even though 99% of the time they won't need to be touched. The wiring has been tidied up and no wires are stretched when working on components. A fuse block was added to protect individual electronic components.

The battery is easily accessible. It's immediately connected to a circuit breaker to help protect the battery and components from electrical shorts, and provides a convenient red on, off switch.
