TL;DR

I am trying to make a robust wheeled-quadruped robot that can operate in "human-scale" environments. It's an ambitious project that's both a creative outlet and an excuse for me to learn new things. Heavily influenced by sci-fi but I'd like it to have some practical applications too.

Status:

• Early stage experimentation complete. 
• Overall concept refined. 
• Core chassis and "head" constructed. Part-tested with simple software.
• Linux and ROS researched and successfully installed on Raspberry Pi 3B+.
• Overall system architecture drafted.
• Head position controllable via UART (-4800 to +4800) or by pot.
• First stab at power distribution and management including UPS for RPi. UPS being a PITA.
• Camera pitch gimbal printed and mounted along with additional structural parts for organising head components.
• Flex-spline gearbox printed for evaluation.
• …

Crude concept, lacking wheels, arms and any detail - work in progress
