Presence induction radar module Robot obstacle avoidance shuttle vehicle obstacle avoidance radar, today, robots can be seen everywhere in our daily life. There are many types of robots, including industrial robots, service robots, patrol robots, and epidemic prevention robots. Their popularity has brought convenience to our lives. If the robot cannot move quickly during the movement. Accurately perceive the environment. The measurement robot is likely to collide with obstacles or people, resulting in economic losses or personal safety accidents.
Based on the radar principle, the presence sensing radar module with independent intellectual property rights can realize fast, accurate and stable distance measurement. Integrating it into the robot can provide the robot with real-time distance information, help the robot to quickly identify surrounding objects, and achieve fast and accurate obstacle avoidance.

Application principle
Integrate the presence sensing radar module into the front of the robot or around it. The installation height can be adjusted according to the form and scene requirements of the robot. The installation height is generally greater than 10cm. The radar will provide distance information to the robot's MCU in real time. The early warning range of obstacles can be set in the MCU in advance. Within a safe distance, the robot can move independently. Within the warning range, the MCU will control the robot to decelerate. Steering and other operations to avoid the robot colliding with obstacles.
Some applications
Outdoor cleaning robot. Outdoor inspection robot. Substation inspection robot. Logistics distribution robot. Elevated railway inspection. Industrial automation robot. Snow sweeping robot.
There is an application of the sensor radar module shuttle vehicle obstacle avoidance radar. In the three-dimensional warehouse, there are many shuttle vehicles on the track, and the running speed is high to avoid collision with each other. Safety accidents reduce the efficiency of warehouse operation. The integrated presence sensor radar module can be installed in four directions of the shuttle. The four directions can monitor obstacles in all directions or the distance from the vehicle ahead in real time. When encountering a sudden obstacle or stopping other vehicles, the radar can be used. Real-time feedback of distance information enables the system to control the shuttle car to decelerate or stop in an emergency in time.
Advantages of radar module obstacle avoidance solution:
1. High measurement frequency, standard 100Hz, up to 1000Hz, fast response, high adaptability to running speed.
2. Small FOV, accurate ranging, small size, easy to integrate inside the car body.
3. High cost performance and high ranging performance.
With the development of the market logistics industry, manpower cannot support the huge logistics and transportation system, resulting in inaccurate data. Managers are unable to deal with out-of-stocks and warehouse explosions in a timely manner, which greatly reduces the operational efficiency of logistics and transportation. In order to increase customers' market share and transportation efficiency, and reduce labor and overall transportation costs, AMR&AGV&RGV obstacle avoidance solutions have been launched to help the industry develop towards a more stable, flexible and faster automation direction.
The installation and use scenarios of AMR&AGV&RGV can be simply divided into two categories: indoor and outdoor:
1. Outdoor application:
Outdoor: refers to the AGV with autonomous navigation function. Its main application scenarios are mainly concentrated in the outdoors, such as streets, factories, office buildings, supermarkets, etc. Its functions include: cleaning, security, patrol, distribution, etc. Generally divided into: outdoor cleaning AGV, outdoor security patrol AGV, substation patrol AGV, logistics and distribution AGV, etc.
Application description
Install the presence sensor radar module in front of the AMR&AGV&RGV, and feed back the direction and distance information of the obstacle to the AMR&AGV&RGV. After the machine is processed, it will give an early warning or avoid obstacles.
Power inspection: Power station inspection robots are mainly used in indoor and outdoor substations, not by inspectors. The robotic system carries a thermal imaging camera. Visible light CCD and other related power station equipment detection devices can detect outdoor high-voltage equipment in an independent and remote control manner, and timely detect internal thermal defects of power equipment. External mechanical or electrical problems, such as foreign objects, damage, heat, oil leakage, etc., provide relevant data for operators to diagnose potential accident hazards and failure precursors in the operation of power equipment.
Advantage:
Increased frequency of periodic inspections;
Flexible operation time;
Outdoor safety: intelligent safety patrol robot, with integrated Internet of Things, artificial intelligence, cloud computing and robotics, with functions such as autonomous navigation, face recognition, and voice interaction.
Advantage:
low cost;
Flexible operation time;
Monitoring without dead ends;
Outdoor cleaning: a robot with independent cleaning function, with independent walking function. Navigation function. Collision avoidance function. Automatic cleaning function. Compared with traditional cleaners, it can save the part of manual operation and complete the cleaning of streets, factories, office buildings and properties independently.
Advantage:
No recruitment pressure;
low cost;
Flexible operation time;
Clean without dead ends;
Logistics and distribution: The distribution robot is the terminal in the ecological chain of the intelligent logistics system. It faces a very complex distribution scenario and needs to deal with the on-site environment of various order distributions. the way. pedestrian. In various scenarios of other vehicles and users, timely and effective decisions are made and implemented quickly, which requires delivery robots to have a high degree of intelligence and independent learning capabilities.
Advantage:
low cost;
Flexible operation time;
large load;
2. Indoor application
Indoors are mainly used to store AGVs, service AGVs, etc., and are mainly used to store AGVs. Here, we will focus on storing AGVs. Storage AGV system: It consists of a series of hardware systems such as picking robots, mobile shelves, replenishment/picking workstations, etc. With the artificial intelligence algorithm software system as the core, a complete order intelligent fulfillment system is completed, including the processes of shelf, picking, replenishment, return, and inventory. The main application scenarios include storage e-commerce logistics, and a few manufacturers apply it to production chains such as automotive industry production.
AGV is selected as the core module for storing AGV. In all business processes involving the sorting warehouse area (including shelves, replenishment, picking, inventory, returns, etc.), the target shelves are transported to the workstation as specified by the system. After the employees complete their business under the guidance of the system, they return the racks to the sorting warehouse area.
3. Other indoor applications and obstacle avoidance solutions
①Special-shaped vehicle
The presence sensor radar module is installed in front of the forklift fork foot, and the distance information of the obstacle in front is fed back to the forklift. After the forklift system is processed, it should be used for collision avoidance or auxiliary positioning of the pallet position.
Advantages of the scheme: The industrial control industry has been cultivated in depth for a long time, customized non-standard for customers, and has a high degree of matching. In the low-cost obstacle avoidance industry, this solution has a certain influence.
② Orbital robot.
