Pneumatics since it is lighter and is better for space on the bot.
Also, how should we put pneumatics on the claw. We have 4 pneumatic kits.
Piston with the plastic due to weight. Have tank(s) on the way bottom. Solenoid near the bottom also. For the pistons, use two of the same size (top and bottom of the claw). That should be good.
Should we use motors or pneumatics on the arm?
