Day 56 of Learning Robotics! Finally got my frameless motors so this is gonna be the next evolution of my actuator. My prototype taught me a lot about motors and gearboxes but in order to build a decent robotic arm I have to use internal actuators and what better way to learn than to build one myself. Actuators can actually make up to 70% of the costs on humanoid robots so if you want to learn robotics, this would be an important chapter. #engineering #robotics #motors #roboticarm #actuator
