Also, there was a picture posted (somewhere) of the plastic tank remnants. I have been unable to locate said picture. Also, there were a few threads posted on CD, commenting on the FIRST safety post.
The safety bulletin suggests that the tank should not be stressed, and in our installation it is securely mounted to the board. However, As weight is not a problem on this test bench, I will build either a plywood or sheet metal cover plate.

Thanks once again for the safety tip!

- Three double solenoids (one 24 v, two 12 v) to power up to six actuators
- Manual push buttons to actuate each solenoid
- Quick disconnect for additional loads
Update 27 Oct 2013
- I have added a separate power supply for the pump: the "on board" one powers the relays and instrumentation
- Per above suggestions, an pressure switch drives an automotive relay to cycle the pump

To do:
-The "air production module" is now complete. I will put a Lexan screen over the plastic tanks per the above safety discussion.
-I am now working on the "test bench" module. This is where you can quickly lash up different mechanisms and try them out.
- I need some sort of "tinker toy" parts quick to assemble arms, gears, cams, grippers, levers, etc.
- I need to have alternate inputs to allow solenoid actuation from the robot cRIO
- My son (in Electrical Engineering program) is developing a data analysis systemm with pressure and position transducers, force load cells, and a PC-based data recording system so we can quantify performance and compare designs.

If anyone has good ideas or would like to team up, please let me know!
