Elephant Robotics Mercury Humanoid Robot B1 (4011300002)

What if the quickest way to teach a robot a task were simply to do the task yourself? The Elephant Robotics Mercury Humanoid Robot B1 (4011300002) is built around that idea. Paired with the myController S570 exoskeleton controller, it achieves 1:1 motion replication, so an operator's movements become the robot's movements. For labs, classrooms and demonstration spaces, that turns abstract talk about embodied intelligence into something you can see and try.

Background

Elephant Robotics and the Mercury line

Elephant Robotics is a robotics manufacturer known for compact, accessible machines aimed at education, research and light automation. Its catalog runs from small collaborative arms to mobile platforms and humanoid designs. Within that catalog, the Mercury series is the humanoid family, and the Mercury B1 sits beside the Elephant Robotics Mercury Humanoid Robot A1 (4011300001) and the Elephant Robotics Mercury X1 Wheeled Humanoid Robot (4011300003).

The series supports major programming languages and popular simulation platforms such as ROS, Moveit, Gazebo and Mujoco. For a team that already works in those tools, the B1 does not ask for a new workflow. It fits into the one the team already has.

Positioning and key technology of the Mercury B1

The Mercury B1 is a compact humanoid platform with 17 degrees of freedom and a maximum working radius of 450mm. Its product size is 200*192.5*537mm, and it is built from carbon fiber, aluminum alloy and engineering plastics. Joints use a harmonic reducer, a common choice where smooth, precise motion matters, and each joint is held by an electromagnetic friction plate brake.

Repeatability is stated as ± 0.05mm and the maximum payload as 1KG. Those figures place the robot in the precision-oriented, light-load class. It is a platform for careful manipulation, teaching and prototyping, and it is not meant for heavy lifting.

On the computing side, the B1 carries a 6-core NVIDIA Carmel Arm®v8.2 64-bit CPU with 6MB L2 + 4MB L3 at 1.9GHz, a 512 core NVIDIA Volta architecture GPU with 64 Tensor Cores, and a computing power of 67 TOPS. A 9-inch touching screen gives the operator a direct way to interact with the robot.

Which Mercury B1 figures should I compare before ordering?

The sources describe the Mercury B1 in more than one way, so compare carefully. One specification page gives 8KG net weight and 67 TOPS of computing power, with the CPU and GPU listed in the table above. A shop page lists 11.2KG and 21 TOPS. A version with a Jetson Orin Nano 8GB is listed at 40 TOPS.

These figures belong to different descriptions of the product, and none should be mixed with another. If weight or computing power decides your purchase, for example because of a mounting limit or a vision workload, state that in your request so the right configuration is settled when your quotation is prepared.

How does the exoskeleton controller change the way you use the B1?

Most robot programming happens at a keyboard. You write a trajectory, test it, correct it and test it again. The myController S570 exoskeleton controller adds a second path. The operator wears or holds the controller and moves, and the robot reproduces that motion one to one. For tasks that are hard to describe in code but easy to demonstrate, such as handing over an object or arranging items on a bench, this is a faster way to explore what the robot can do.

It also makes the platform easy to show to visitors. A student who sees their own gesture mirrored by the robot understands the idea of teleoperation immediately. On the software side, the B1 supports both ROS1 and ROS2, with RVIZ simulation environment support. A team can therefore rehearse in simulation, then move to the physical robot, or collect demonstrations by exoskeleton control and process them in the tools it already uses.

Who is the Mercury B1 for?

University labs and research groups are the clearest fit. They need a humanoid form with 17 degrees of freedom, repeatable positioning of ± 0.05mm, and an open software environment with ROS, Moveit, Gazebo and Mujoco. Technical schools and training centers can use the same features to teach kinematics, vision and control on real hardware instead of simulation alone.

Developers prototyping service robots will value the 3D camera, the four-microphone array and the touching screen, which together cover seeing, hearing and interacting. Exhibition and demonstration organizers can use the humanoid form and the exoskeleton pairing to draw attention.

Buyers who need to move a heavy load should look elsewhere, since the maximum payload is 1KG. Teams that want a different humanoid configuration can look at the Mercury A1 (4011300001) or the Mercury X1 Wheeled Humanoid Robot (4011300003), and compare them against their own requirements.

What is the Mercury B1 used for?

1. Research in embodied intelligence: a humanoid platform on which perception, planning and manipulation algorithms can be tested on real hardware.
2. Teleoperation and demonstration: with the myController S570, an operator's motion is replicated one to one for precise control.
3. Simulation-to-real development: work in ROS, Moveit, Gazebo or Mujoco, then run the result on the robot.
4. Teaching robotics: classes on joints, reducers, brakes, sensors and communication buses, using a machine students can see and handle.
5. Vision and voice interaction: use the Orbbec Deeyea 3D camera and the line array microphones to build interactive applications.
6. Exhibitions and demonstrations: a compact humanoid with a touching screen that presents robotics to visitors in a clear and engaging way.

Summary

The Mercury B1 earns its place through one idea: a robot that learns from a person's movements as readily as from code. It has 17 degrees of freedom, a harmonic reducer, ± 0.05mm repeatability, a 3D camera, a microphone array, and support for ROS1, ROS2 and the common simulation platforms. It suits labs, classrooms and demonstration spaces that value precision over payload. If that matches your plans, this page is the starting point.
