This way the creators of the robotic hand are able to generate the required pneumatic pressure (to move its different parts) without employing any heavy external air pumps. As the pressure inside the balloons changes, the mesh tubes contract or expand accordingly. Moreover, the robotic hand has a total of 36 artificial muscles.

Similar to the muscles of a normal human hand, the artificial muscles also have 27 degrees of freedom, meaning that the robot's thumbs and fingers can move, rotate, and hold just like the way their human counterparts do. The Clone Robotics team suggests that In the future, their artificial hand could be used as an appliance to perform various tasks in homes, factories, and laboratories, plus, it also has the potential to make humanoids more advance than ever.

The engineers at Clone Robotics didnt achieve success in creating the V15 robotic hand on their first attempt. Getting the hand work without air pumps was just one challenge. Initially, the hand weighed 18.3 lbs (8.3 kg), contained only 20 muscles, and could work for up to 5000 cycles. The engineers kept on improving their model until they were able to reduce its weight to 9.47 lbs (4.3 kgs).
