Introduction of ROS Controllers
There are 2 types of ROS Controllers available for use with the RRobotbased on the Vidia Jetson platform. Jetson Orin Nano is suited more towards research and education. Jetson Orin NX is ideal for product prototyping and commercial applications. The following table illustrates the main technical differences between the various controllers available from Roboworks. Both boards allow high-level computation and are suited to advanced robotic applications such as computer vision, deep learning, and motion planning.
Sensing System: LiDAR & Depth Camera
A Leishen LSLiDAR is installed on all Rosbot variations with either the N10 or M10 model being used. These LLiDARsoffer a 3360-3360-degree scanning and surroundings perception and boast a compact and light ESI. They have a high Signal Noise Ratio and excellent detection performance on high/low reflective objects and perform well in strong light conditions. They have a detection range of 30 meters and a scan frequency of 12Hz. This LiDAR integrates seamlessly into the Robots, ensuring all mapping and navigational uses can be easily achieved in your project. The below table summarizes the technical specifications of the sliders:
Additionally, all Robots are equipped with an Orbbec Astra Depth Camera, which is an RGBD camera. This camera is optimized for a range of uses including gesture control, skeleton tracking, 3D scanning, and point cloud development. The following table summarizes the technical features of the depth camera.
STM32 Board (Motor Control, Power Management & IMU)
The STM32F103RC Board is the microcontroller used in all Rosbots. It has a high-performance ARM Cortex-M3 32-bit RISC core operating at a 72MHz frequency along with high-speed embedded memories. It operates in -40°C to +105°C temperature range, suiting all robotic applications in worldwide climates. There are power-saving modes that allow the design of low-power applications. Some of the applications of this microcontroller include motor drives, application control, robotic applications medical and handheld equipment, PC and gaming peripherals, GPS platforms, industrial applications, alarm system video intercoms, and scanners.

Steering & Driving System
The Steering and Driving system is integrated with the design and build of the Robot. Depending on the model purchased it will be either a 2-wheel or 4-wheel drive, with both options being suitable for a variety of research and development purposes. The wheels on all Robots are solid rubber with snow-protection grade tires. There is a coaxial pendulum suspension system, and the range Robots are equipped with shock absorbers with independent suspension systems, ensuring they can successfully navigate difficult terrain.

Power Management
Power Mag – Magnetic LFP Battery:
All Rosbots come with a 6000 mAh Power Mag, a magnetic LFP (Lithium Iron Phosphate) battery, and a Power Charger. Customers can upgrade the battery to 20000 mAh at an additional cost. LFP batteries are a type of lithium-ion battery known for their stability, safety, and long cycle life. Unlike traditional lithium-ion batteries, which use cobalt or nickel, LFP batteries rely on iron phosphate, offering a more sustainable and less toxic alternative. They are highly resistant to thermal runaway, reducing the risk of overheating and fire. While they have a lower energy density compared to other lithium-ion batteries, LFP batteries excel in durability, with longer lifespan, faster charging, and better performance in extreme temperatures, making them ideal for electric vehicles (EVs) and energy storage systems. Power Mag can be attached to any metal surface of a robot due to its magnetic base design. It makes swapping batteries quick and easy.

Auto Charging Station (Power+):
Auto Charging Station is bundled with the Rosbot 2+ model and can be purchased separately to work with Rosbot 2, Rosbot Pro, and Rosbot Plus.
ROS 2 Quick Start
When the robot is first powered on, it is controlled by ROS by default. Meaning, the STM32 chassis controller board accepts commands from the ROS 2 Controller – The Jetson Orin. Initial setup is quick and easy, from your host PC (Ubuntu Linux recommended) connect to the robot’s Wi-Fi hotspot. The password by default is “Dongguan”.Next, connect to the robot using SSH via the Linuxterminatee l, The P address is 192.168.0.10and 0, and the default password is Dongguan.
With terminal access to the robot, you can navigate to the ROS 2 workspace folder, under “wheeltec_ROS 2” Before running test programs, navigate to wheeltec_ROS 2/turn_on_wheeltec_robot/ and locate wheeltec_udev.sh – This script must be run, typically only once to ensure proper configuration of peripherals. You are now able to test the robot’s functionality, to launch the ROS 2 controller functionality, run: “relaunch turn_on_wheeltec_robot turn_on_wheeltec_robot.launch”
In a second terminal, you can use the keyboard_teleop node to validate chassis control, this is a modified version of the popular ROS 2 Turtlebot example. Type: “relaunch wheeltec_robot_rc keyboard_teleop.launch”
