Day 57 of Learning Robotics!

Designed and started 3D printing the inner core for my internal cycloidal gearbox. This time instead of spawning things in like I did earlier with my prototype, I decided to walk you guys through the math behind the decision-making and why I chose to parameters that I did. I’m also going to do my best to cite the research on mechanical, electrical and AI systems that I’ve been reading. Once we have a finalized version of the internal cycloidal gearbox, we can officially build a robotic arm for AI research which will be incredible.
