Recently, Candela's 2021 new product, the Sunshine Multifunctional Sanitation Robot , was officially released, which has been reported by many industry media. Sunshine Multifunctional Sanitation Robot has the functions of ground sweeping, dust reduction and humidification, garbage running, garbage dumping, etc., and it can be switched independently according to the demand, so as to realize the full coverage of the working scene. Today, I explore with you to see the ultrasonic perception behind this clean "superman".
Obstacle avoidance perception: L4 automotive technology
As we all know, cleaning robots as an important tool for urban environment maintenance, need to walk through the crowded streets and alleys, driving technology must keep up.
Sunshine Multifunctional Sanitation Robot: arrange!
The cruising system of Sunshine Multifunctional Sanitation Robot takes L4 automotive technology as the core, integrating ultrasonic radar, laser radar, binocular vision and other multimodal sensors, sensing the surrounding environment in 360°, realizing automatic driving, intelligent decision-making, etc., and actively avoiding and bypassing pedestrians, vehicles or other obstacles to ensure safe operation.
The ultrasonic obstacle avoidance solution matched with L4 automotive technology is independently developed and provided by AUDIOWELL, the industry's leading ultrasonic sensor manufacturer and solution provider. The Sunshine Multifunctional Sanitation Robot installs ultrasonic sensors around the main body, from which ultrasonic waves are emitted by the sensors and reflected back when they meet an object. The sensors convert the distance to the obstacle by calculating the time difference between the emission and reflection of the sound waves, generating data information. Combined with AI algorithms, the solution is able to obtain real-time information about obstacles around itself, including the size, shape, and location of the obstacles, to quickly depict a map of the obstacles and plan the driving path.
Safety perception: high-energy protection system
In terms of safety advantages, in addition to the superior driving technology, the Sunshine Multifunctional Sanitation Robot is also profound in self-protection.
Sunshine Multifunctional Sanitation Robot consists of three parts: the main body, vacuum box and garbage bin, in which the main body is matched with the vacuum box, which is mainly used for vacuuming and cleaning. At the beginning of the vacuuming mode, the vacuuming box is light in weight and easy to be overturned due to external force. In order to prevent such accidents from happening, Sunshine Multifunctional Sanitation Robot loaded AUDIOWELL ultrasonic warning solution on the vacuum box, the sensor installed outside the vacuum box continuously sends out ultrasonic waves, and utilizes the TOF principle to project whether there is an external object at the safe warning distance of the vacuum box. When the sensor detects that the external object is at the safety warning distance, it will trigger the defense mechanism of the Sunshine Multifunctional Sanitation Robot and send out an alarm signal to warn the triggering person and the surrounding passers-by, avoiding safety accidents triggered by the overturning of the vacuum box.
Capacity Sensing: Fully Automatic Dumping Function
From the functional point of view, the Sunshine Multifunctional Sanitation Robot, which is also a cleaning robot, has installed an intelligent capacity recognition system, which gets rid of the "retarded old way" of the traditional sweeping robot and realizes the fully automatic dumping function. The system applies the AUDIOWELL vacuum box capacity detection solution, the use of ultrasonic ranging principle, detecting whether the remaining capacity of the vacuum box is sufficient, insufficient will issue a warning signal; the solution combined with the AI algorithm, you can start the automatic dumping function, clever fully automatic structure design, the whole process without human intervention.
Thanks to the ultrasonic sensor's high weather-resistant performance and the fact that the detection accuracy is not affected by the environment's light and darkness, the Sunshine Multifunctional Sanitation Robot can adapt to the all-weather environment, and continue to work at night, in high temperature and cold environments.
From the application scenarios of Candela's Sunshine Multifunctional Sanitation Robot, we can see that ultrasonic sensors give the robot more sensing ability, they can not only give the robot sensing function from the outside, but also can be used to detect the internal working state of the robot itself, which effectively ensures and improves the robot's own operation and sensitivity. In the future, AUDIOWELL will continue to plough into intelligent sensors, actuators, their modules and application solutions, and promote the robot industry to realize more intelligent and convenient application scenarios.
