Reliability Testing
The complete hand has undergone more than 100,000 fatigue-test cycles, supporting durable and dependable operation over extended use.
Test results may vary with the application scenario, model and configuration [2].
Drop Testing
Validated through more than 100 drop tests, the Dex2/5 is engineered to better withstand bumps and impacts during operation and handling.
No drop height or formal impact-protection rating is stated in the supplied product data.
Integrated Cable Routing
Internal cable routing keeps wiring within the hand's structure for a cleaner, more integrated form. Dex2/5 is compatible with Unitree G1 and R1 products.
Confirm the exact robot version and configuration before ordering.
Compact Form
At 365 g, the Dex2/5 measures 151 × 70 × 63 mm when the hand is laid flat [1], combining a compact footprint with a five-finger tendon-driven structure.
Motion and Gripping Overview
Dex2/5 combines 10 total degrees of freedom with 2 active degrees of freedom. The thumb has 1 active degree of freedom, while the index, middle, ring and little fingers share the other active degree of freedom.
