Remote control: The Pi 5 version runs Raspberry Pi OS with ROS 1 Melodic or ROS 2 Foxy in Docker, the Jetson Nano runs ROS 1 Melodic with ROS 2 Foxy in Docker, and Orin boards run ROS 2 Humble on Ubuntu 22.04. A laptop connects over SSH, VNC or ROS networking for RViz.

Overview

Yahboom's older Ackermann rover, first sold in 2022 and updated with Pi 5 and Orin Super boards, and the only robot in this group with a published top speed (1.8 m/s). Every kit includes an Astra Pro Plus depth camera, and the course uses it for RTAB-Map and ORB-SLAM2 3D mapping. The Astra's 0.6 m minimum range is a limit for close following, and the Pi 5 and Jetson Nano images use ROS 2 Foxy, which is past end of life. It costs more than the newer ROSMASTER A1, which has a more current Humble course and LLM chapters.

Specifications

Category	Wheeled rovers · Ready-made dev rovers
Released	2022
Country	China
Availability	Available
Programmability	Full SDK
Built-in autonomy	Navigates · Goes to places on its own, such as mapped rooms, waypoints or its charging dock
LLM support	Built-in LLM chat · Yahboom's R2 course adds LLM tutorials that run chat models such as DeepSeek-R1, Qwen2, Llama 3 and Phi-3 on the robot's board, but these are not tied to robot control. Voice commands use a separate command-word module on the Ultimate kit. Yahboom tutorials ↗
