This modular wrist joint component was developed to integrate with the original Hexa-Flex Modular Arm system and is designed to provide adjustable, lockable mechanical positioning across multiple degrees of rotational freedom. The assembly includes a free-swing configuration that allows unrestricted movement within the socket when unlocked. The joint supports angular adjustment between 0 and 45 degrees around a full 360-degree rotational axis and is intended for mechanical positioning in a variety of use scenarios. This specific wrist configuration is designed to interface with the lightweight forearm section of the Hexa-Flex Modular Arm system and may be removed from the forearm shaft for servicing or maintenance.
