Finger binary Finger binary Finger binary is a system for counting and displaying binary numbers on the fingers of one or more hands. It is possible to count from 0 to 31 (2−1) using the fingers of a single hand, or from 0 through 1023 (2−1) if both hands are used. In the binary number system, each numerical digit has two possible states (0 or 1) and each successive digit represents an increasing power of two. Note: What follows is but one of several possible schemes for assigning the values 1, 2, 4, 8, 16, etc. to fingers, not necessarily the best.
Kanguera used for user friendly human machine interface and for upper limb rehabilitation technologies. The hand has an anthropomorphic shape, and is the size of a large human hand. It has 4 fingers, and a simplified thumb, each one with four degrees of freedom (DOF). Each finger is treated as an individual robot, giving the overall system, from the wrist on, 20 DOF in total. The fingers are constructed from a special resin, and the joints are designed to mimic human joints - they are not physically joined, but in close contact, using the resin's friction and cables to work together.
