Robot Hand Based on Multifunctional Tactile Sensor for Warehouse Application

With the rapid development of e-commerce, the smart warehouse and delivery industry is increasing dramatically. Robot hand is the important equipment in this industry and its key technology is to improve the stability and accuracy of the manipulator in the process of sorting and handling process by using tactile sensor. In this work, we have developed new sensing materials and fabrication process to produce flexible multifunctional tactile sensors by using printed electronic technology. They are light and durable, and can test the pressure distribution and bending changes accurately during the grasping process. We have installed several sensors on the front and back of the robot hand, and designed a testing feedback system. It can monitor the dynamic process of grabbing in real time and send it to the control system, greatly improving grasping and object identification performance. It can be integrated with the artificial intelligence algorithms to provide intelligent sorting and handling process for smart warehouse application.
