The robotic claw fun but not that practical !

What else can be put on the end of a robotic arm besides a claw or hand that's fine for someone who has a physical challenge who may need it or a medical purpose of some kind so at the end of the day I realized that if the claw or hand aren't getting "worked" so to speak they are a waist of space plus  I've already done the claw and the hand so where does it leave off I think navigation or some kind of sensor array are far more useful in every day robotics ! Especially the ones here including duce I removed the removable appendage  another sensor cluster is in order maybe an oled  definitely after that sensor episode bill made
