A robotic arm that i programmed to be controlled by the nxt brick. pushing the left and right buttons turn the arm while pressing the center button causes the arm to move forward the first time it is hit then move backwards the second time and then stop again when it is hit for a third time. hitting the touch sensor opens and closes the hand.
i think that later on i am going to make a bluetooth version so stay tuned. thanks
