Parallel gripper end effector designed to interface with the differential wrist, featuring an internal slip ring for continuous rotation. Utilizes a four-bar parallel gripper mechanism actuated by dual 45 kg·cm DF Robot servos with internal gear reduction, providing up to 181 N of grip force. Constructed from 2.5 in × 1/16 in tube stock and designed as a detachable hand module for rapid iteration and tool changes.

Compact elbow motor module developed as an MVP for Arm 3.0 motor modules. Uses a NEO 1.1 brushless motor and Harmonic Drive 71-100-118879-11 reducer to deliver 110 Nm rated torque, controlled by an ODrive motor controller. Housing and structure machined from 6061 aluminum. 

Compact wrist providing pitch and roll motion via dual CubeMars motors and custom hypoid bevel gears rated for 30 Nm torque. Torque is transferred using HTD belts around a static 0.5" T-shaft. Designed to support a 5 kg payload and seamlessly interfaces with the hand and forearm.

Encases electronics including the motor controller (O-Drive), fuse boards, and a buck converter (24 V to 12 V) in a serviceable enclosure. Features panel covers and internal mounts for easy access, wiring management, and protection. Attached at end of the forearm, covering any exposed holes near electronics 

Interfaces with the differential wrist via a hypoid bevel gear and spins on a dead axle T-shaft. Features a slip ring for continuous rotation and a servo-driven, modular finger design rated for a 5 kg load. Reinforced with metal plates for structural integrity and easy finger replacement.
