Darth Vader robotic arm

Guess losing a limb in the far away future isn’t too much trouble since you can always settle for robotic arms and legs that are far more durable than the human equivalent, and besides, you can start winning arm-wrestling competitions at bars to fund your lifestyle without anyone else knowing better. Well, until that day comes, you’ll just have to be satisfied with fixing together your own Darth Vader robotic arm which comprises of 45 snap-together parts. When assembled, the arm can extend and turn, while closing and opening its fingers to grasp objects. We wonder whether there is any sensitivity sensor involved so that it won’t crush a delicate eggshell while holding on tightly to a glass of water without breaking it.
