Robots Everywhere with Aaed Musa
Aaed Musa, a mechanical engineering student at Purdue and YouTuber, explains how he builds low-cost quadrupedal robots like 'Kara' using off-the-shelf brushless motors and custom 3D-printed capstan drives to achieve high precision with zero backlash. He details the engineering trade-offs between torque, speed, and cost, noting that optimizing these factors allows him to build a robot for $1,300, significantly cheaper than commercial equivalents like Boston Dynamics' Spot. Musa also discusses the importance of integration in robotics, the role of AI in simplifying kinematics, and how his hands-on projects serve as a practical portfolio for his career.
