Just1 is an open-source robotics platform built for learning and rapid experimentation. It supports manual and autonomous navigation, path following, and obstacle avoidance. With a bill of materials around $250, it offers an affordable way to explore robotics, ROS 2, and autonomous behaviors.

The hardware includes a Raspberry Pi 4, mecanum wheels, TT motors, a 2D LiDAR, Raspberry Pi camera, and an IMU. The software stack is based on ROS 2 Jazzy, with RTAB-Map for SLAM, Nav2, and Foxglove integration.

I created Just1 as a simple, low-cost platform to experiment and to share with the community. Upcoming work focuses on simulation support (Gazebo / NVIDIA Isaac).
