Week 6: Parts and Prototypes

This week, the Arduino Uno and FSRs arrived in the mail. Having had no prior experience with either, we were quite surprised by the small size of all the parts (Figure 4):

The Amazon package also included wires and a breadboard. These parts will be mounted on the glove to control the servo. During testing last week, it was also determined that the servo's rotation was not sufficient to fully open and close the hand; a motor with infinite rotation was needed.  The servo was then modified so
that it could still be used. The servo rotation is demonstrated below:

Next, the prototype of the hand was started with just the index finger mechanism. The artificial tendon system was made using fishing line, rubber bands, paper clips, coffee straws, and other various household materials. Currently, the mechanism has not been finalized (rough video below). Once the mechanism has been finalized, the other fingers will be fitted.
