Fighting servo EMI: shortening wires beat aluminum foil shielding in practice
philfung · x · 2026-11-15
- A robotics developer hit electromagnetic interference from large servos for the first time.
- After many failed attempts, two fixes actually worked: (1) wrapping wires and motors in aluminum foil, (2) shortening the wires.
- The author went with shortening the wires — a useful first-hand datapoint for anyone building physical robots.
