Humanoid robot with ultrasonic wave eyes

Abstract

The present invention provides a humanoid robot with ultrasonic wave eyes. Through matching with a head motion mechanism, a set of ultrasonic sensors are arranged at the eye portions of the humanoid robot to allow the detection angle of the humanoid robot to be wider and have more directivity, reduce the hardware cost and the program complexity of the robot and improve the ornamental value of the humanoid robot. The humanoid robot comprises a humanoid robot head, an ultrasonic ranging module is fixed at the eye portions of the humanoid robot head and comprises two ultrasonic sensors taken as the robot eyes, the robot head has a steering engine capable of driving the head to move, and the steering engine and the ultrasonic ranging module are both connected with a robot main control board which emits control signals to control the synchronous movement of the ultrasonic ranging module and the robot head and emit detection signals to allow the robot to realize the multidirectional ultrasonic scanning detection through the head motion.

Description

Technical field [0001] The invention belongs to the technical field of robots, and particularly relates to a humanoid robot with ultrasonic eyes. Background technique [0002] Ultrasound is a mechanical wave with a vibration frequency higher than 20KHz. It has the characteristics of high frequency, short wavelength, small diffraction phenomenon, especially good directivity, which can become rays and propagate directionally. Ultrasound has a great ability to penetrate liquids and solids, especially in solids that are opaque to sunlight. When the ultrasonic wave hits the impurity or the interface, it will produce a significant reflection to form an echo, and it can produce a Doppler effect when it hits a moving object. Ultrasonic sensors are sensors that convert ultrasonic signals into other energy signals (usually electrical signals). At present, ultrasonic sensors are widely used in industry, national defense, biomedicine, etc. Ultrasonic sensor has the characteristics of adj...

AI Technical Summary

Problems solved by technology

Ultrasonic sensors vary in size and can be easily installed on different devices. Generally, when used for robot obstacle avoidance or detection distance, they will be installed on the chest\back\hands\feet and other parts. If you need to detect more For data in three spatial directions, only by increasing the number of ultrasonic sensors can all-round detection be realized, which virtually increases the cost and complexity of the program.
