  Ontario, Canada, has a project using the STAMP to
  control an artificial hand for young amputees

10
How it Works

• User gives commands through a PC keyboard
• These commands are relayed through the RF
  transceivers to the blimp
• The blimps on-board intelligence interprets the
  commands and performs the corresponding functions

12
The Ground to Air Transmission

• The Basic Stamp II gives the transmitter the
  appropriate bit pattern
• The On-Board Stamp then receives the bit pattern
  from the receiver
• Based on the bit pattern received, the Stamp will
  set the appropriate bits high or low

13
The Motors

• The On-Board Stamp is interfaced with the motor
  driver circuit
• Propeller motors are used
• There is an enable and a fwd/bwd signal for each
  motor

Problems to solve

• reverse directions of two motors at particular
  points in their travel
• ensure that the moving arms dont become and
  remain synchronized

48
PIC is used to

• check when the motors have hit their CW and CCW
  limit switches
• reverse the motors direction
• add a little delay to the time it takes one of
  the motors to reverse directions in order to
  prevent synchronization
