The robotic arm is now fully operational. It has 6 Degrees of Freedom and can be controlled remotely from any laptop running the interface software.The robotic hand is capable of simple tasks such as lifting and carrying small objects. I have attached a wireless AV camera to the robotic hand. A human operator can now “see” what the robot is doing and issue commands accordingly over the wireless data link.
To test the working of a robot hand like the one I built earlier, I needed a haptic control glove that would encode the flexing of my fingers into electrical signals. These signals would be interpreted by a microcontroller (like the ATMEGA328 on the Arduino platform) and cause the servo motors on the robot hand to mimic my finger movements inside the glove. Electronic puppetry.
