Why Robot Arms Still Cant Handle a Screw

Episode 54 of The Robotics Podcast: Lucas and Luna tackle the surprisingly difficult problem of robot arms driving a screw. Why is this basic assembly task still beyond most industrial robots? They break down the physics of torque control, the difference between position control and force control, and why a six-axis arm struggles with the simple act of turning a fastener. The discussion zeroes in on a 2025 research paper from MIT's CSAIL lab that achieved 92 percent success rate on a standardized screw-driving test board, and what that reveals about the gaps in current robotic hardware and software. They also touch on why this matters for industries like electronics assembly and automotive manufacturing, where screws are still mostly driven by human hands. A concrete look at an unsung bottleneck in automation. #RobotArms #ScrewDriving #TorqueControl #IndustrialRobots #Automation #MIT #CSAIL #ForceControl #Assembly #Manufacturing #RoboticsResearch #PrecisionAssembly #Hardware #RoboticsPodcast #FexingoBusiness #BusinessPodcast #Technology #SixAxisRobot Keep every episode free: buymeacoffee.com/fexingo
