LiDAR-equipped small robot: tabletop-sized educational robot material
The Light Rover is an educational robot kit equipped with a Raspberry Pi 4 Model B (4GB RAM version) and a compact LiDAR (LRF) mounted on an easy-to-handle tabletop-sized cart robot chassis. With a projection area of 160mm square, it is suitable for learning purposes on a desk and can operate in limited spaces, making it usable in more scenarios than ever before. Despite its small size, it is equipped with LiDAR (LRF), allowing it to accurately recognize the surrounding environment. It also supports control via ROS, enabling easy experimentation and practice of modern controls required for cart robots, such as executing SLAM utilizing the computational power of the Raspberry Pi 4. 【Features】 ■ Standard equipped with Raspberry Pi 4 Model B and LiDAR (LRF) ■ Achieves speed control via encoders ■ Can be powered from mobile batteries and other sources ■ Comes with sample programs necessary for learning ■ Camera unit for Light Rover is also available in the lineup

Applications/Examples of results
While being equipped with all the necessary features for learning, a major characteristic is its low price of under 50,000 yen at the regular price. By providing a sufficient number of practical teaching materials as needed, it contributes to enhancing educational effectiveness. The two drive motors mounted on the Light Rover come standard with encoders, allowing for accurate measurement of rotation. In addition to enabling speed control through PID control based on motor rotation, it can convert this information into odometry data, facilitating various applications such as SLAM and autonomous driving for learning and development. Furthermore, a new control board for the motors, "VS-WRC201," has been developed, which inputs the output values from the encoders into the Raspberry Pi 4, achieving efficient motor rotation control. 【Application Examples】 Research and development robots, transport robots, two-wheel drive robots, autonomous driving robots, conveyor robots, AGVs, etc. *For more details, please feel free to contact us.
Detailed information

The Light Rover comes standard with a compact housing, featuring a 4GB RAM version of the Raspberry Pi 4 Model B and a small LiDAR (LRF). In modern autonomous control of cart robots, the demand for computational power has increased more than ever, and the Raspberry Pi 4 provides sufficient processing speed to meet this need. LiDAR (LRF) is increasingly being integrated into smartphones and home appliances, and it is expected to become an even more important device in the advancing field of robotics control. This product, which packages these key devices compactly, can be considered an excellent educational material not only as a learning tool for autonomous control but also as a means to create entirely new computing devices that go beyond simple cart control.

This product uses four AA nickel-metal hydride rechargeable batteries as the standard power source, but the power connector on the motor control board VS-WRC201 adopts a universal USB micro B terminal. This allows for the connection of commercially available mobile batteries or AC adapters in addition to the standard power source. With this design, during the development process where long operating times are required, an AC adapter can be used, while for actual robot operation, AA nickel-metal hydride rechargeable batteries or mobile batteries can be used, allowing for flexible selection of power supply methods according to the situation and purpose. Please note that this product does not include AA nickel-metal hydride rechargeable batteries, mobile batteries, or AC adapters.

The Light Rover comes with sample programs that make it easy to learn ROS. Based on these sample programs, you can execute SLAM and other functions via ROS, allowing beginners in mobile robot control to progress from basic levels. Documentation to facilitate smoother learning is also included as standard.
-
There is also a "Camera Option for Light Rover" that allows you to add a camera to the Light Rover equipped with LiDAR. The camera unit can be easily assembled and can be utilized for advanced program development that combines LRF and the camera. We also offer a set that is more economical than purchasing individually, so please consider it. (Note: Even if you purchase as a set, the installation of the camera option must be carried out by the customer.)
