Assembling the Wearable Flexible Supernumerary Robotic Limb and its Testing with Healthy Volunteers

To begin, take the designed pneumatic gripper and secure it with 3D printed parts. Using adhesive tape, attach it to the appropriate position on the glove. Embed three flexible bending sensors into the glove.

Instruct the participants to flex and extend their fingers. Use a data acquisition card to record sensor signals, amplify the sensor signals and route them to an RDU o. Now, collect data on the range and pattern of sensor changes during finger movements.

Instruct participants to move their fingers freely within their range of ability. After determining the threshold, determine the appropriate time to stop inflating the air and cease further finger bending. Set the maximum air pressure for the pneumatic gripper to 100 kilo Pascals.

Solicit feedback from the wearers regarding their experience. The survey of six patients showed a consensus among most participants regarding the comfort and user friendliness of the designed wearable system. Participant five provides a less favorable evaluation and raises significant concerns about the device.
