±2° Angular Error at Sub-Second Rotation: Single-Axis PID Swerve Fails Day-After Repeatability Test
🚩 Robotics: Yet Another PID Loop Wrapped in Hype
A PID-controlled swerve system failed its own turn initiation the day before—and then barely held ±2° stability with a 0.2s loop. 🚩 Universal Robots holds ±0.03mm at 1,000mm/s. Path Robotics welds at ±0.1mm under 10kg. Kawasaki&
