XGO-lite3/mini2S: World’s First Raspberry Pi Robotic Dog with An Arm
Intelligent, agile, and open-sourced, XGO brings the latest automated robotic dog technology to your desk at an affordable price.The 15-DOF Series: Mobile Manipulation for Everyone.
In 2023 KickStarter, XGO 2, World’s First Raspberry Pi Robotic Dog with An Arm
1.Quadruped Platform (lite3 & mini2S)
The XGO Quadruped Platform is more than just a robot dog; it is a Desktop Mobile Manipulator. Both the lite3 and mini2S come standard with a 15-DOF architecture: 12 DOF for Locomotion: Enabling omnidirectional movement, 6D posture control, and terrain adaptation. 3 DOF for Manipulation: An integrated Robotic Gripper (Arm) for picking, placing, and interacting with the environment.Powered by the unified Raspberry Pi CM5 brain, they share the same codebase but utilize distinct actuation technologies to serve different developmental stages.
