Analysis of the three major requirements of intelligent robots for sensors
Release Time:2019-11-16

As far as intelligent robots are concerned, sensors are an indispensable part, and sensors are very important for each link. Nowadays, the external sensors of most intelligent robots can be roughly divided into mechanical sensors, tactile sensors, proximity sensors, and various types of sensors such as vision, slid, and thermal sensation. In this way, intelligent robots have appropriate and stringent requests for sensor accessories. Below, Xiaobian will give you a detailed request for the smart robot to the sensor.

The first is the accuracy of the sensor.

With regard to intelligent robots, sensor requirements are high precision, high reliability, and stability is necessary. With the assistance of the sensing system, the intelligent robot can self-stand the work specified by humans. If the accuracy of the sensor is slightly poor, it will directly affect the quality of the robot's work; if the sensor is unstable, perhaps the reliability is not high, and it is very simple to cause the intelligent robot to present a problem. The lighter causes the operation to be unable to operate normally, and it will form a serious incident when the weather is severe. Therefore, the reliability and stability of the sensor are the most demanding requests of the intelligent robot.

For example, in some special environments, such as underwater robots commonly used in underwater environments, it is often necessary to use a large number of base components such as MEMS accelerometers and gyroscopes, because in addition to the small footprint of MEMS sensors, more importantly, These sensors are more timely and robust for the transformation of some weak analog signals. Therefore, MEMS sensors are the aspirational accessories for the professional development and manufacture of industrial robots.

Followed by anti-interference

Since the sensor of the intelligent robot usually operates in an unknown environment, the sensor is required to have an anti-electromagnetic disturbance to disturb the harsh environment such as dust and grease. The light weight and small volume are also the requirements of the sensor on the robot. For the sensor on the moving part of the robot arm, the component must be light, otherwise it will increase the damage of the moving component and affect the motion function of the robot. With regard to robots whose working space is subject to certain constraints, requests for volume and device orientation are also essential.

Some multi-joint robots, such as serpentine articulated robots, are capable of detecting in some shaded, space-constrained orientations. In addition, in order to overcome some of the sensors that are vulnerable to external disturbances, some robots use infrared sensors that are not disturbed by electromagnetic waves, and can perform non-touch measurement, and complete the advantages of day and night measurement.

Final sensor device question

The safety question of intelligent robots is first of all self-maintenance, and the other is the way robots are adopted to maintain human security without aggression. When human beings are working, they always use their own feelings to react and control the ability to use muscle strength without surpassing the bones and tendons. Similarly, during the operation of the robot, the force and torque sensors are selected to inspect and control the force condition of each component so that each component does not exceed its force limit, and then the maintenance component is not damaged. In order to avoid collision between the robot and surrounding objects, various tactile sensors and proximity sensors are required to avoid collisions. Intelligent robots serve human beings. In order to protect humans from harm, intelligent robots require sensors to constrain their own practices.
