With the breakthrough of artificial intelligence technology and the decline of the cost of core components, the intelligent service robot industry has ushered in vigorous development, and the demand for robot chassis based on autonomous positioning and navigation is also increasing. This function is an indispensable and important hardware for robots. Such an important robot chassis, what core technologies does it consist of? Today, I will popularize the chassis structure of the robot for everyone.
1. Core components inside the robot chassis
Taking the robot chassis Apollo of Silan Technology as an example, the internal structure of Apollo is mainly composed of laser radar sensors, depth cameras, ultrasonic and anti-drop sensors, modular positioning and navigation system SLAMWARE, and other core hardware. It has a reliable and easy-to-use autonomous positioning and navigation solution, and multi-sensor fusion and navigation algorithms can more flexibly plan the robot’s walking route.
Using the lidar sensor, it can scan the surrounding environment at all times, provide map data, build a map with an accuracy of up to 5cm, and realize autonomous path planning and navigation functions based on the map data;
depth camera sensor
The depth camera sensor can detect obstacles located above the radar scanning plane and send signals in time to avoid them;
When the ultrasonic sensor is working, it can accurately detect obstacles such as glass and mirrors with high transparency, so that it can avoid them in time before approaching these objects;
The anti-drop sensor can help the robot to detect the surrounding working environment 360°, determine whether there are boundaries, steps, slopes, etc. in the working area, so as to send a request signal to avoid falling;
Modular Positioning and Navigation System (SLAMWARE)
The modular positioning and navigation system has a built-in navigation and positioning core module of the SLAM engine, which is highly integrated and can directly output a map of the environment where the robot is located, positioning coordinates and attitudes without external computing resources, and has built-in multiple robot motion control algorithms, which can provide centimeter-level positioning and positioning. Map accuracy, real-time planning of paths in unknown environments, and obstacle avoidance navigation to find the shortest path autonomously.

In addition to the autonomous positioning and navigation and path planning functions of the robot chassis structure, the autonomous recharging technology is also indispensable, and the autonomous recharging technology adopted by Apollo can be externally scheduled for charging. When the power is low, it will automatically return to the charging dock to charge, and it can work continuously for 15 hours under load conditions, providing stable and reliable performance for the application site.
Open software and hardware interfaces at the same time, support multi-platform operation, convenient for users to switch quickly, fully open user interface, including Ethernet, control interface, power supply and other expansion interfaces, support Windows/Linux/Android/IOS development environment interchange, 90% of the The interface definitions are the same, which is convenient for users to switch quickly.
3. Robot chassis application scenarios
As a small and medium-sized robot chassis, Apollo’s design can meet multiple scenarios such as shopping malls, office buildings, hotels, and terminals. Based on a complete and reliable bottom-level application, the upper-level application can be custom developed. Significant time, effort and cost savings can be achieved in the development of technology and production.
Today, the service robot market is constantly expanding, and the demand for mobile robot chassis based on autonomous positioning and navigation is also increasing. It has been widely used in restaurants, hotels, shopping malls, security and other fields. The requirements are also getting higher and higher, and at the same time to reduce the cost, it is necessary to design a high-performance, low-cost robot chassis.
