The air muscle is made of a soft inner tube encased in a strong plastic mesh. The assembly is held together by metal clips on each end. The plastic mesh is looped at each end making a hole. The plastic mesh hole is very strong mechanically and can be used to attach the air muscle to any device. Figure 16.5 shows a machine screw inserted through the mesh hole.

Using the air pump adapter
When you receive your foot pump, it will have a standard air nozzle as shown in Fig. 16.6. We need to replace the standard nozzle with the air pump adapter. Lift the locking lever as shown in Fig. 16.7.

You need to acquire a plastic PET bottle. The easiest way to do so is to buy a soda. Make sure the soda bottle is plastic. Don t purchase a

soda bottle larger than 1 liter (L). A half-liter bottle is ideal. I ve tried the bottle cap adapter on all sizes of PET soda bottles up to 2 L, and it fits all of them. Empty the PET bottle of soda and clean it out with tap water. The bottle should be completely dry before using. It s interesting to note that if a full bottle of soda is dropped, the resulting pressure caused by the release of the carbonated soda greatly exceeds the 50-psi limit we impose on the bottle. Soda companies have designed PET bottles to withstand a rapid increase in bottle pressure, which would come from dropping the bottle. This is something I never realized before working with the air muscle, and thought I would pass it on. Remember, no glass bottles should be used in the air muscle pneumatic system.
Building the first demo device
The first mechanical device we will build is a simple one that can be used to measure the contraction of the air muscle (see Fig. 16.10). The base is 1" 2" lumber and is 11" long. I used this material simply because I had it lying around. You can just as easily use metal or plastic. At each end I drilled a hole to accept a 13/4"-long 8-32 machine screw. The machine screws are inserted and held in place using two 8-32 nuts, one nut on each side of the wood. The head of the screw and shaft protrude about 3/4" above the wood. The top screw is threaded through the top opening of the air muscle, before inserting the screw into the wood. A rubber band is looped through the bottom opening of the air muscle and then

looped around the bottom screw. The rubber band stretches the air muscle when it is in its relaxed state. Connect the balance of components as shown in Fig. 16.4. At times I ve had difficulty connecting the 5/32"-diameter tubing to some of the components. Here are a few tips. First, if the tube refuses to go onto an adapter, place the tubing under running hot water from the faucet. This softens the plastic, making it easier to fit onto the components. Another trick is to use some clear plastic tubing. The plastic tubing is snug enough to fit onto the adapter nozzles properly (see Fig. 16.11). In addition it is pliable enough to fit the 5/32"-diameter tubing inside the tubing itself (see Fig. 16.12). The soft tubing acts like an adapter and quick release for changing air muscle devices. To operate the device, first pressurize the system using the foot pump. It only takes about four strokes to reach 50 psi. Your mileage may vary depending upon the size of the PET bottle you are using. Open the three-way air valve to charge the air muscle. The muscle should immediately contract. You can measure the distance it moves in proportion to the psi gauge on the pump. You should be able to operate the muscle through four or five contractions and expansions before you need to refill the PET bottle. The air muscle doesn t use much air. Notice that the air muscle stays in the contracted position until the three-way valve is turned to release the air from the muscle. It doesn t cost any energy to keep the air muscle contracted. This is in contrast to servo motors and solenoids that must be supplied electric energy continuously to maintain their push or pull. If the muscle doesn t appear to contract, then it probably wasn t stretched far enough. Remember the muscle must be stretched in order for it to contract (operate).
