How tilt sensors work in robots, let's take a look.
A robot is a machine that performs work automatically. It can either be directed by humans, run pre-programmed programs, or act according to principles laid down by AI technology. Its mission is to help replace human jobs, such as manufacturing, construction, or dangerous jobs. The inspection robot is one of them. It carries a visible light camera, infrared thermal camera, pickup, ultrasonic wave, inclination sensor, etc. At the same time, it adopts trajectory navigation and can conduct autonomous or remote control inspection of outdoor high-pressure equipment according to the optimal path planning. Through machine vision, infrared temperature measurement, sound detection and other methods, the inspection robot can collect infrared heat map, image and audio information of the equipment. It also automatically identifies the thermal defects, abnormal appearance, switch or tool position, instrument reading, and oil level meter position of the equipment, generates unified and standardized alarm items and inspection reports, sends alarm information to the operator, and provides basic data for equipment status maintenance. In unattended, less attended substations or smart substations, especially in plateau, low oxygen, high cold and other geographical conditions or bad weather conditions, inspection robots can replace or assist manual inspection of substation equipment.
When the inspection robot is crossing obstacles, the partial moment caused by mass eccentricity damages the horizontal posture of the robot body. In order to ensure its smooth progress, a simple and reliable centroidness adjustment method is needed. The tilt sensor ER-TS-4258CU is used to measure the inclination angle between the robot body and the horizontal plane, so as to control the movement of the mobile motor of the counterweight block. When the center of mass of the robot is adjusted to the arm suspended on the overhead ground wire, the measurement angle should be controlled within the range of 90° with an accuracy of ±0.1°, so as to ensure that the robot body maintains a horizontal posture and ensure that the arm that needs to be off-line or online completes the corresponding action. Finally, the feasibility of the centroid control method is verified by simulation experiments.
