I wonder how you could make this with FIRST resources. The compressor could certainly be used for suction. You'd have to have some sort of filter system/mechanism to keep the coffee grains from sucking into the compressor. You might just be able to put a screen inside the balloon. It might be tricky to use this gripper and air tanks for pneumatic pistons, since both require different uses of the compressor and at different times. Then you'd have to figure out how to make/machine an attachment from the balloon to the air hose. This attachment would also have to have mounting holes on it for mounting it onto an arm or the robot.
