Build me a Robotic Hand that Opens and closes rapidly Similar to the hand in the first 3 seconds of this video ([链接已删除,请登录查看]) I need a robotic hand that can simply open and close with 5 fingers as if simulating a human hand. It does not need to go as fast as the hand mentioned in the video, but I would like it to be able to close and open at least 50 times per minute. Also I would like the fingers on the hand to be removable. 3 电子, 微控制器, 电機工程, 机器人技术, Arduino Feb 18, 2018 今天6天 22时 $4310
