Demonstration

For our final demonstration, we added a mounting system where the rollers attached to the input link could have a surface to slide on (acting as the palm). We decided to drive our demo with a servo to better demonstrate how the finger would work on the patient. The mounting system has a section that houses the servo, which we connected to an Arduino and ran using the Arduino software. Here is a gif of our demonstration model.

We utilized lube on the screws and areas of connection to produce a smooth motion but found that this demo was limited by the power of our servo. As a result, the curl in this video is not as much as we designed it for. When the patient uses it, it will be able to have the full range of motion we designed it for. We also mounted the Arduino to the back of our stand and powered it from our laptop. The program that we used to run it can be found in the appendix.
