Manipulation and Perception

The comparison gives 600 mm arm reach; no model-specific rated load was verified. Peak actuator torque does not establish end-effector payload.

Comparison depicts an AMOLED face display, microphone array and stereo perception. Exact sensor revisions and industrial task package require confirmation.

SDK and Integration

Walker S family page names ROSA 2.0 and manufacturing-system integration. Exact interfaces, language bindings and simulator access for this configuration were not verified.
