Human Body Parts Proximity Measurement Using Distributed Tactile Robotic Skin

Safety in human–machine cooperation is the current challenge in robotics. Safe human–robot interaction requires the development of sensors that detect human presence in the robot’s workspace. Detection of this presence should occur before the physical collision of the robot with the human. Human to robot proximity detection should be very fast, allowing machine elements deceleration to velocities safe for human–machine collision. The paper presents a new, low-cost design of distributed robotic skin, which allows real-time measurements of the human body parts proximity. The main advantages of the proposed solution are low cost of its implementation based on comb electrodes matrix and real-time operation due to fast and simple electronic design. The main contribution is the new idea of measuring the distance to human body parts by measuring the operating frequency of a rectangular signal generator, which depends on the capacity of the open capacitor. This capacitor is formed between the comb electrodes matrix and a reference plate located next to the matrix. The capacitance of the open capacitor changes if a human body part is in vicinity. The application of the developed device can be very wide. For example, in the field of cooperative robots, it can lead to the improvement of human–machine interfaces and increased safety of human–machine cooperation. The proposed construction can help to meet the increasing requirements for cooperative robots.

Traditional Catering Industry Carries Cooperative Robots to Achieve Industrial Upgrading

The world-renowned Chinese cuisine has been handed down from generation to generation in the traditional mode of handicraft, workshop and apprenticeship, which is distorted from generation to generation. The quality of dishes in small shops is difficult to guarantee, the works of masters are difficult to replicate, economies of scale are difficult to achieve, waste of resources can not be controlled, and the plight of industrialization has not been broken through. In recent years, with the development of science and technology, especially the growing maturity of cooperative robots, the traditional catering industry has ushered in an opportunity for innovation. Through the application research of multi-joint cooperative robot in Chinese cooking scene, this paper solves the technical difficulties of large-scale mechanization of Chinese cooking, opens up the last kilometer of Chinese food industrialization, realizes the upgrading of traditional catering industry, and also enables the inheritance and innovation of Chinese cooking.
