Program a sub-$2k personal robot
MARS is a general-purpose robot with an open onboard agentic OS built on ROS2.
What they did
The source is a launch post for MARS, an assembled, calibrated robot with a Jetson Orin Nano, a 5DoF arm with wrist camera, an RGBD camera, 2D LiDAR and speakers. You write "behaviors" in the BASIC SDK, which runs the robot like an AI agent with VLAs. Skills come from training the arm or writing code tools, and ROS2 topics allow low-level control.
How it went
The post is a launch announcement and reports no results or measurements. It says the robot boots in a minute and can be controlled by phone or programmed from a PC. Hardware and software are to be open-sourced later.
Worth knowing
A temporary Hacker News code lowers the price to $1,799; the post says it targets hobbyists and education, and the open-sourcing is still planned, not done.
