Joint packaging
Review the useful joint angle, shaft or bore interface, gearing, backlash and the space around each finger joint.
Application / Dexterous Robotic Hands
Compact joint-angle feedback for dexterous robotic hands.
Finger joints in a dexterous robotic hand leave very little space for angle feedback. Cooka’s HRS12 hollow-shaft angle sensor has a 12 mm body and a 3.2 mm profile, so it can sit around the joint shaft; magnetic and custom formats are available when the joint needs a different interface.
Requirements
What the sensor has to handle
Feedback integration
Define the signal, response direction, repeatability and how the wiring passes through the moving finger.
Duty & validation
Agree joint-cycle conditions, temperature, load and the calibration checks for the proposed hand assembly.

Selection
How to choose
- Measure the space around each joint: diameter, depth and the shaft or bore that the sensor must fit.
- Define the useful joint angle and the required resolution and repeatability.
- Decide how wiring leaves the joint as the finger moves.
- Choose between the HRS12, a magnetic format or a custom part built to your drawing.
- Agree the joint-cycle test and calibration method, then request samples.
Buying questions
Dexterous Robotic Hands FAQ
Which Cooka sensor fits a robotic finger joint?
The HRS12 hollow-shaft angle sensor is the usual starting point: a 12 mm body and 3.2 mm profile let it sit around the joint shaft. Magnetic and custom formats are available for other joint designs.
How thin is the HRS12?
The HRS12 has a 3.2 mm profile and a 12 mm nominal body, with an alloy housing.
Can Cooka build a joint sensor to my drawing?
Yes. Send the joint drawing, angle, interface and wiring requirements for a configuration review.
What is the MOQ for Cooka sensors?
The minimum order quantity starts at 10 pieces for standard configurations; custom configurations are quoted per project.
What is the lead time?
Lead time is 3–7 days for in-stock configurations.
Are free samples available?
Yes. Cooka provides free samples for qualified projects.
