The XR-2 robot platform, available at Robots Builder, is designed with user-friendliness in mind, emphasizing accessibility and ease of assembly. Developed to make robotics more approachable, the XR-2 is meticulously engineered for easy 3D printing and assembly using standard components like servos and bearings. The XR-2 is a significantly updated version of the XR-1, which we released last year. We have addressed several weaknesses in the XR-1 and added many new features to the updated XR-2.

The XR-2 supports two single-board computers (SBCs). It uses a PC mounted behind the display in the chest to support Synthiam ARC. It also has a place to mount a Jetson Orin Nano right above it in the PC below the neck for onboard AI server support. On the back, we have a custom servo breakout board with two Mega Minis and USB ports. The power source is two 20V power tool batteries. The robot has 49 degrees of freedom and supports two cameras. There is also room for 10 small Arduinos or sensors in each leg if you choose to add them. Almost every joint in the robot uses bearings to remove structural stress off the servos. With that being said, the XR-2 is a heavy robot.

Our commitment to simplifying the building process ensures that enthusiasts and robot hobbyists of all skill levels can engage in constructing their own robots. We've invested time in perfecting the design, ensuring that users can quickly move on to the exciting aspects of teaching and programming their robots. The XR-2 is highly customizable, featuring a variety of hands and heads to choose from, allowing users to personalize their creations. To foster a collaborative and open community, we're proud to announce that everything about the XR-2 is open source, inviting users to contribute, modify, and share their innovations with the global robotics community. Get ready to embark on a journey of creativity and exploration with the XR-2!
