ROBOT
A holonomic mecanum-drive platform that can move in any direction. In active development.
UPDATED 2026-10-14 · SOURCE project notes (brief §0) · branch AMR4
IN DEVELOPMENT
Fig. 1 AMR4, top view.
Four special wheels with angled rollers, a lidar and an onboard computer. AMR4 is still in development, so this shows the design, not finished results.
FROM PROJECT NOTESSource brief:§0
AMR4 rolls on four mecanum wheels, carries an RPLidar A1 on USB and runs ROS 2 Humble on an NVIDIA Jetson Orin Nano.

Fig. 2 AMR4 specifications.
What AMR4 is built from today. "Absent" means the item isn't part of this robot yet, for example a camera.
FROM PROJECT NOTESSource brief:§0
The 1.0 m/s top speed is a design maximum, not a measured result.

Fig. 3 Moving in any direction.
Mecanum wheels let a robot move in any direction, including straight sideways, without steering. This is a generic drawing of holonomic drive, not a measured AMR4 result. (Illustration.)

Only the motor driver and the wheel odometry are confirmed so far. The empty, dashed boxes are deliberate; they show what isn't built or confirmed yet.
PENDING CODE REVIEWSource brief:§0
Node and topic names are pending code review, so they are not shown.
Source brief:§0
The code lives on the AMR4 branch of a private repository. A public link will appear here once the repository is opened.
