Abstract

The invention discloses a robot bionic flexible electronic skin with controllable global rigidity. The system comprises a three-level sensing system. The first-level sensing is approaching sensing, is composed of a capacitive approaching flexible sensor array, and can sense the approaching distance, approaching speed and approaching direction of a man-machine. Secondary sensing is sensitive contact sensing, and a sensitive flexible tactile sensor with a bionic hair structure is adopted, so that contact force can be detected; the three-level sensing is load-sensitive tactile sensing, a flexible tactile sensor and a flexible driver which are integrated are adopted, the rigidity of the flexible electronic skin can be globally adjusted, the contact pressure can be detected, the measuring range and the sensitivity can be changed, and then dynamic load self-adaption is achieved. According to the invention, multi-source and multi-mode signals can be detected through a multi-stage sensing system.

Description

technical field [0001] The invention relates to a sensing device, in particular to a robot bionic flexible electronic skin with controllable global stiffness. Background technique [0002] Robots are now widely used in production and life, and robots inevitably need to interact with people and the environment in daily production and life. Safety is the most basic and important link in the process of robot interaction with humans and the environment. [0003] In order to improve the safety of human-computer interaction, the traditional methods include covering the robot with flexible materials, mechanical limit, etc., but these methods are passive control methods after the collision event occurs, and can only minimize the impact of the robot on the outside or Injury to the human body cannot be actively avoided. Actively sensing the external environment and predicting an emergency, the robot takes emergency control measures, such as actively stopping, returning in the approa...
