I made a robot that can pick up stuff and drop them. I used a tool thats called gripper to make it work. I programed the robot to pick and drop stuff. the use of the robot is to grab stuff that people want, an example is this one: you are watching a m ovie and you want to get chips or something you need, of course, you dontlike to get up and go grab it, so you can program the robot to give you things.
