The final prototype needed some kind of cover to complete the appearance of a blob. Our intention was to have a very tight material that wrapped around the entire sculpture. We imagined a latex-like covering that wrapped around the sculpture like an air-tight, semi-transparent skin. We purchased a lycra fabric at a local reuse store and found that the lycra was too strong for the servo motors to push the arms through. The servos were not powerful enough to move the arms. We therefore had to make the lycra cover fairly loose. In further iterations, we would focus on transforming the bag-like covering into a tightly wrapped, flexible skin.
