Where should a pneumatics tank be placed on an over under bot? ( looking for your guys thoughts)
The closer to the ground as possible would be better to lower your center of gravity to prevent tipping.
It truly depends on the robot, but just don’t have it exposed (on the side, front, back, etc.), as that can bring damage to it.
Keep it lower to the ground. If you want to place two pneumatic tanks, keep both of them close to eachother.
