OYMotion ROHAND ROH-AP002 Dexterous Hand
Five-finger ROH-AP002 with 11 movable joints, 6 active DoF and 6 motor drivers. V1.0.2 documents finger force sensing and a 55-site palm matrix; interface, power and load limits need their stated configuration and posture.

Choosing this model
Read the product documentationSourcebotics selection notes, based on the published documentation.
Application fit
- Force-feedback manipulation experiments requiring finger and palm sensing.
Integration planning
- Specify LB/RB handedness and the -C suffix if CAN is required. Confirm the interface-specific voltage and connector pinout before selecting the power supply.
- Use the model-specific ROS/ROS2 and serial examples as an integration starting point; confirm the target environment and SDK release.
- Request the mechanical drawing for the shipped revision: English and Chinese V1.0.2 manuals disagree on palm width and thumb-tip-to-wrist distance.
Selection considerations
- The 30 kg figure is passive support with four fingers bent, not an arbitrary dynamic lifting payload.
- Do not interpret the 55 palm sites as the whole hand’s total taxel count, or the 0.1 N normal-range lower bound as force resolution.

Discuss this configurationFAQ
Does ROH-AP002 have six fingers or eleven active axes?
No. It has five fingers, eleven movable joints, six active DoF and six built-in motor drivers. The manual does not separately specify eleven independent DoF.
Does the 30 kg value mean it can dynamically lift a 30 kg object?
No. V1.0.2 describes a maximum passive load with four fingers bent. It separately lists 10 kg for one bent finger and 8 kg for one straight finger. Object contact, posture and dynamic handling need their own assessment.
Which interface and supply voltage apply?
The -C suffix identifies CAN hardware. V1.0.2 specifies RS485 12–24 V DC and CAN 12–48 V DC, but the product page and connector row state 24 V. The manual gives 48 W rated power; the page gives ≤15 W typical and ≤0.5 W standby. Confirm the exact interface, revision and power definition with the supplier.
Are 0.1 N resolution and ±0.05 mm repeatability confirmed by the manual?
The manual identifies 0.1 N as the lower bound of the normal-force measurement range, rather than resolution. Specify the product listing’s ±0.05 mm repeat-positioning figure together with its measurement conditions and numeric acceptance criteria in the purchase brief.
Why are some dimensions not presented as one number?
Both V1.0.2 manuals give 183 mm from middle fingertip to wrist. English gives 82 mm palm width and 97 mm thumb-tip-to-wrist; Chinese gives 83 mm and 95 mm. Request the drawing for the shipped revision before making a mount.
