The Autonomous Mobile Robot (AMR) market is growing at 22.3% CAGR (2023-2030), driven by demand for flexible automation in warehouses, hospitals, and factories. Unlike traditional AGVs, AMRs require:
Real-time dynamic path planning
Millimeter-level positioning in crowded spaces
Instant torque adjustment for collision avoidance
Servo systems address these needs through closed-loop control, sub-millisecond response, and intelligent energy management.
