Our project is an actualization to the old mechanical prosthesis that exist now a day. There are a lot of prosthesis in the market that helps to recover the mechanical part of your hand but there is no prosthesis capable of getting you senses of touch and sensitivity to temperature back. For this reason we work in develop a system to get back all this senses. After a long thought we decide to publish this project so we can contribute with our part to the world. The idea is that with this we can help the people that lost this sense.
The way we manage to recover the temperature sensibility was placing temperature sensors to the hand (or Claw in the case of the prototype) and some RGB leds that lights up in different colors. By averaging the total temperatures we assign a specific color to each temperature. In this way when the object taken was between 0 to 10 degrees Celsius the hand its going to light up in a blue color, then when the temperature rises in 10 degrees the hand will become green, then pink, then purple and so on till it gets red in 100 degrees Celsius.
Our gripper was made from a budget of 130 dollars aprox, and was made from recycled materials, mainly aluminium and steel. The gripper was poured of resin and hand machined with a dremel to give the final finish.
