Here is my vex version of the 2005 FRC game Triple Play. The arm can extend to 41" and folds up to fit inside an 18"x18"x18" box. It is being used at fundraisers at the moment for my high schools robotics team.
cool, here is mine that I made, it’s a replica of team 1002’s 2005 robot. the base is a holomonic drive system and the main arm piviots and extends out.
