Red Rabbit Robotics RX1

描述

RX1 is a human-scale dual-arm humanoid that Red Rabbit Robotics gave away. Rather than keep the design in-house, the company published the CAD, the bill of materials, the servo, arm, hand, head and torso hardware files and a ROS 1 driver — its own claim is that you can build one for under a thousand dollars from 3D-printed parts and off-the-shelf components. The robot is a torso on a stand rather than a walker: two arms of seven joints each, a three-joint torso and a two-joint neck, counted from Red Rabbit's own URDF. The hands are separate open hardware, as are the gripper and the teleoperation arm. Motion runs on Feetech servos through the company's own driver; perception uses an Orbbec depth camera on the head. The software side is a ROS 1 meta-package: URDF description, servo control, an inverse kinematics demo with a drag-the-end-effector marker, a Gazebo simulation and a single launch file that brings everything up. It can be driven from a computer through machine learning or from a VR headset, and a matching teleoperation arm maps an operator's movement onto the robot. For Red Rabbit the open robot is the shop window: the commercial offer is a pilot of robot workers, initially remote-operated and eventually autonomous.
