Robot setup. (a) An overview of the experimental setup that consists of a UR5 robotic arm, Robotiq 2F-85 gripper, a GelSight sensor and an Intel RealSense D415; (b) The GelSight Sensor; (c) A sketch diagram of the GelSight sensor.
Note:
Our tactile poking method is not limited to the GelSight sensor [1], and also works with other tactile sensors such as the tactile finger [2] and the GelTip sensor [3].
