Elephant Robotics Mercury X1 is a 1.2-meter high wheeled humanoid robot with two robotic arms using an NVIDIA Jetson Xavier NX as its main controller and ESP32 microcontrollers for motor control and suitable for research, education, service, entertainment, and remote operation.
The robot offers 19 degrees of freedom, can lift payloads of up to 1kg, work up to 8 hours on a charge, and travel at up to 1.2m/s or about 4.3km/h. It’s based on the company’s Mercury B1 dual-arm robot and a high-performance mobile base.

The Mercury X1 wheeled humanoid robot can be programmed with Python and ROS 1/2 (Robot Operating System), and Elephant Robotics provides robot driver libraries installable through PyPI for querying joint angle data, Cartesian coordinate data, etc., and an RVIZ simulation environment for ROS1 and ROS2, plus a range of hardware drivers and software libraries.
The documentation has instructions on how to get started and a few demos/tutorials for QR Code Recognition and Grasping, Spatial Movement, Mobile Grasping, and Keyboard typing. I could not find anything about the ESP32 firmware and all instructions are high-level Python or ROS code or commands. I also feel the documentation could be improved as things like specs seem incomplete, and while the product page mentions a “Mercury API is a C++ control interface”, it’s nowhere to be found in the documentation.
The Mercury X1 can be purchased on Elephant Robotics for $15,999 US, which happens to be the starting price of the Unitree G1 2-legged humanoid robot with NVIDIA Jetson Orin, but lacking any programming guide as the Unitree robot looks to be configurable through a mobile app only. It’s also possible to purchase a subset of the Mercury X1 with the Mercury B1 with the upper body only (i.e. without the mobile base) for $11,999 US, or one Mercury A1 7-DOF robotic arm for $4,999 on the same page.
