The MIT Mini Cheetah LS is a small, agile four-legged research robot (a variant of MIT’s Mini Cheetah) designed for dynamic maneuvers.In this project, we discovered that a CNC actuator gear had developed a cracked tooth. Repeated cyclic loading can lead to bending fatigue cracks in gear teeth, and insufficient design margins or long-term wear may eventually result in severe wear or tooth failure.To address this issue, the gear was redesigned in CAD and fabricated using PCBWay’s CNC machining service. PCBWay offers high-precision CNC machining with tolerances as tight as ±0.01 mm, making it well-suited for robotics prototyping and custom mechanical parts.This video provides a technical walkthrough covering mechanical troubleshooting, CAD-based redesign, and precision manufacturing—relevant for robotics engineers, researchers, and advanced hobbyists.
