The robotic hand can be interfaced to an IBM-compatible computer
using five electric solenoid valves, similar to the single-valve design
shown earlier. An outer covering like a rubber hand can be fitted
over the robotic hand to make an android hand (see Fig. 16.29).
Some other applications for the air muscle are interesting. Here
are a few:
Six-legged robotic walker
Easy-open jar clamp (for people with arthritis)
Robotic hands
Robotic arms
