Do you remember the robotic arm that Tony Stark has in the Iron Man movies? Sure, it is unable to talk back, but in its silent movement, it was still capable of conveying a certain sense of “emotion”, so to speak. Don’t you wish that you too, had some sort of robotic arm at your disposal to be able to help you out in some household chores? What you see above would be a video of such an arm, where it remains in the prototype stage while being made out from 3D printed parts, with the help of an Arduino chipset as well as Adafruit analog feedback servos.
This prototype trainable robotic arm gained its inspiration from the Baxter robot, where it can be specially trained to move with your own hands. The moment the train button is pressed, you will be able to move the arm and gripper as required, while the Arduino will store the positions in the EEPROM. Once that is done, the arm will replay the motion as required. Not exactly the kind of self-aware robotic arm that we would have liked to own, but at least it is a start in the right direction for the average home user, no?
