Developing a Low Cost Robotic Hand for a Big Brain, Robot, Human, Humanoid or Android
We took this China cybernetics robot hand toy and reworked it into a master hand for humans or androids by adding functions and developing techniques for using it in a variety of conditions
LEFT: the robotic hand is extended showing the fingertip rubber pads for tactile gripping and holding onto objects more securely. Linkages in the bendable finger joints are visible. The hand will extend your arm by 55cm (about 22-inches).
LEFT: the robotic hand is in the process of grabbing and removing technical laser equipment from navigational aerospace systems created for SPACE1 Industries. The robotic hand is capable of extending reach into relatively inaccessible places and places beyond the reach of humans, for example on high shelves.
The poly construction robot hand has five digits including one opposable thumb. The fingers are controlled with a metal steel linkage that allows the hand to close the fingers at will to pick up things. Each finger has four bendable sections with the fingertips having attached rubber grommets for increasing tactile engagements. The opposable thumb is static and stationary without movement.
The lightweight robot hand is easy to use and only costs about US$3.00 plus shipping. It's spectacular in functions and can pick up most mid sized and mid weight objects easily. The real value comes in using it for useful real world applications and having fun. The hand is manufactured and shipped from China. The unit is overall portable and easily carried around and transported. Warning: as with human arms, the robotics arm has similar limitations - do not try to pick up excessively heavy items or the mechanism may be strained and exceeded.

Adding Applications to the Robotic Hand
The robotic hand will generally pick up medium size and weight objects, however this can be greatly extended.
* To pick up much smaller objects, use the hand to slide the object to an opposing wall or object and scoop it up.
* To pick up objects much smaller that set flat on a table or the floor, attach with medical tape a series of woman's artificial fingernails. This will allow prying under the object and make it more easy to pick up very small flat objects and coins. A beauty store has any number of fingernail varieties for sale. Strengthen the artificial fingernails by applying a layer of metal tint fingernail polish. Given the high cost of beauty products, fabricate your own fingernails using a thin sheet of plastic and sheen cardboard, cut to fit.
* Keep the robotics arm by the bedstead hanging on a S hook where is can readily be grabbed and held as a convenient attachment to the human body
