Product description
The AC-2 kit contains two genuine Aeon quasi-direct-drive actuator modules rated at 120 Nm peak, the exact units fitted to hip and knee joints on A-series humanoids. Whether you are refreshing a high-mileage robot or repairing impact damage, these are the same parts, from the same line, with the same QC as factory builds. Each module integrates motor, 9:1 planetary stage, dual encoders and driver electronics in a sealed 1.4 kg package. The kit includes fresh mounting hardware, thermal pads and Aeon's handheld calibration tool, which writes joint offsets and friction tables automatically during first boot. A step-by-step replacement guide with torque specs is included; typical hip or knee swaps take an experienced owner about 45 minutes per joint.
