The kinesics is the study of body movements and is an important part of the communication.
This project is about bringing that language to robotics, to interact with a device without having to use other interface as a keyboard or a jostick. It is necessary for this type of control will be intuitive for the user to feel comfortable using it.
An accelerometer is used to obtain the position of the hand and a FM transmitter tells to the receptor that is installed in the car the movement to be carried out.
You can us any RC car or you can build one. If you haven't one, you only need to put the 2 geared motors, the caster wheels, one protoboard and the li-po battery in the acrylic chassis. I use a bluetooth controlled car like base for HandBot.
First you need to verify to correct operation of the RF devices. This will be easy by a LED indicator, the control will be managed by two keys "w" and "s" of your computer's keyboard.
Now, you need to verify visually with LEDs the four outputs that should go to the H bridge, reds colors indicate forward, greens colors indicate backward, one red and one green colors indicate the turn left or right respectively. The control will be by the keyboard of your computer "8" fordward, "2" backward, "6" turn right, "4" turn left, "5" stop.
Connect the red LEDs to pin 9 and 7, the green LEDs to pin 8 and 6.
