The DexRobot 021S is a lightweight, three-fingered dexterous hand engineered to cover the majority of practical manipulation tasks at a form factor and cost suited to production deployments and research platforms. At 0.6 kg, it reduces wrist-level inertia compared with heavier five-finger hands, and its three-mode intelligent transmission — combining gear, tendon, and linkage mechanisms with rigid-flexible coupling — delivers grip forces ranging from 22 N at the fingertip up to 100 N peak at the base. DexRobot describes the 021S as targeting 80% of core hand manipulations, making it a pragmatic choice for tasks like electronic component assembly, conveyor sorting, cable harness insertion, and laboratory instrument handling.

The 021S body uses a bionic elastic soft exterior with a micro-textured surface for improved object contact, and the platform has passed a 200,000-cycle loaded life certification, confirming durability for continuous operation. Standard sensing combines joint angle feedback with vision; optional tactile sensing is available for slip detection and force-limited grasping. Position control via CAN FD or RS485 provides a deterministic integration path for scripted trajectories and repeatable pick-and-place routines, while open-source SDK support and multi-protocol compatibility accelerate secondary development across research and industrial environments.
