Air muscles were chosen for the bionic arm design as they offered low weight, medium cost and strength while carbon fiber, though most expensive, provided great strength and lightweight properties. An electric hand was not selected due to limitations in power, movement and weight despite budget constraints.

2. Air muscles were a good choice because they were low weight, medium cost, and medium strength.

3. While Carbon Fiber is the most expensive choice, it is also very strong, and lightweight. This makes it a good choice

4. An electric hand offered little power and degrees of freedom, and was heavy. However, our budget didn’t allow for a nicer hand
