**Designers:** Eric Bubar (remix of Skip Meetze’s Gripper Thumb Terminal Device)
**Description:**
This design is an attachment for a voluntary opening, gripper-style terminal device. It allows for attaching a high-torque servo, Arduino Nano, and rechargeable batteries to the back end of a terminal device to actuate a cable that will pull the voluntary opening device open. It has been tested on a gripper thumb terminal device design from Skip Meetze and the TuuTree terminal device from Fricis Pirtnieks. The design is thoroughly documented with photos, instructions and a list of materials.
