Construct & create moving a robotic hand that comes in kit form, meaning you have loads of fun building it and even more fun playing with it. The hydraulic cyborg hand simulates the movement of a human hand using hydraulic power for mechanical transmission without electricity. It allows every finger joint to adjust at different angles for a precisely closed fist or open palm. You can use different grip techniques to hold a variety of items, such as bottles, balls or tiny screws, making it an interesting and fun challenge.
