Step 6: Stuff and inflate

Everything is done now, we just need to stuff the bladder and inflate it.  Starting with the extremities, tie the loops on the bladder onto the envelope.  Push the nozzle through the inflation hole and distribute the bladder evenly around the inside of the envelope.  Talcum powder  helps the bladder slide into position, and sit better.  Start pumping air into the bladder, all the while massaging the robot to eliminate spots where the bladder doesn't properly fill out the fabric envelope.  If all goes well, you'll have a robot punching bag!
