The SAA has a total of six tools: scissors, pliers, tweezers, saw, flick-fire missiles, and laser cutter. The tools are attached with beams directly to the motors as shown in the main picture. Pictures of the scissors, tweezers, and pliers can be found in step one above. Scroll down for more info on the pliers. The saw is made of orange Bionicle teeth attached next to the scissors and can be seen in the scissors picture in step one. The laser cutter (small pics 1-3) is a short fiber-optic cable found in some Exo-Force sets that uses the NXT light sensor to illuminate it. The flick-fire missiles are shown in the last picture
The claws of the pliers have small tires on them to give them more grip.
The pliers are powered by a pneumatic cylinder attached with a long pneumatic hose to a Power Functions comperssor kept in the user's pocket. More info on the compressor in next step.
The compressor is operated by hand by flipping the small orange switch. This turns on the motor which pumps the small pump.
The pictures show how the robot attaches to the user's arm. Small picture #2 shows the back arm bracket. You pull the beam at the bottom off of the blue peg, slide your arm in, then put the beam back. The wheel is for comfort as the original bracket dug into you arm and left a LEGO shaped mark an the user's arm. The trigger activates the laser cutter.
Here is the whole program. I did not use any MyBlocks, mini blocks, or anything that did not come with the software. The NXT buttons activate ther tools and the trigger activates the laser cutter. I will try to get a movie but I have been expieriencing problems.
