First off, Chris, I really wish you would include the various parts needed for the gripper (the solenoid and such) in the manual in the bill of materials / parts section like you do with the actual gripper... I didn't even think to look to see if there was anything else needed when I ordered all the parts, so now I need to put in more purchase orders to get the rest... Second- what are you guys using for a Pneumatic source? I know that the FRC teams use a small 12V air pump, pressure regulator, control board (to know when to pump more air) and something like .5L storage tanks. Is this something we could add (and standardize) so as to make it a common setup? It would automatically pump up pressure at startup, get it into the storage tank and then turn off the pump and only come back on as it is needed (as the gripper gets used). How much pressure do we need for the gripper to function?? Here's the info on what they use for FRC: https://firstfrc.blob.core.windows.net/frc2017/pneumatics-manual.pdf

Hi All In the process of building a 3d-printed AR3 and wanted to confirm the J5 encoder settings. In the manual on page 158 it says to set the J5 encoder to 512 steps per revolution, however in the teensy sketch J5encMult is set to 2.56. Is this a typo in the code or manual, or is this an expected difference? Thanks! Corey

I currently use a LeArm robot arm to learn programming and integration. it uses a custom Arduino uno board with a a ”run program” analog button. How would I activate the AR3 to run the programmed movement?
