We actually rebuilt the arm on the third day to be more rigid, but I suppose it could be damaged in a collision. We haven't tried.
The pressure to the pneumatics that raise the arm is limited by a regulator to around 30 psi or so to conserve air, but even at full pressure we don't tip when lifting the arm. Sudden acceleration with the arm raised makes us tip slightly, though.

How did you connect the CIM to the planetary gearbox? Vex doesn't support this, but I have heard of others doing it as well.
Thanks!!!
...if the penalties were not significant and match-deciding then there would not be much incentive to pay attention to them, would there? - dtengineering [more]
