As my tutor is interested in researching in robots. One Sunday afternoon, he asked me to do a research on robotic gripper. After the research, I recommended him use the soft 3D printing one, later he printed the model out. Combined with the computer vision algorithm used to locate items, then we can make more components in an industrial robot.

还有一种就是用3d打印出的

感觉是3d打印爱好者玩的比较多，有网站给出了制作步骤，功能上与视频中相近
