Canonical robot record
Overview
The Mercury B1 is a dual-arm, semi-humanoid robot developed by Elephant Robotics, a Shenzhen-based Chinese robotics company. It is built around two seven-axis A1 robotic arms mounted on an upper-body frame, allowing each arm to operate independently or for both to coordinate on bimanual tasks. The platform is marketed primarily toward research, education, and human-robot interaction rather than industrial automation.
The robot integrates an NVIDIA Jetson edge-computing module as its main controller, an integrated 3D camera for machine vision, a linear microphone array for voice interaction, and a head-mounted touchscreen that can display customizable facial expressions. Together these enable perception-driven manipulation, grasping, and immersive VR-based teleoperation.
Mercury B1 is supported by a broad software ecosystem, including common programming languages and popular simulation and robotics frameworks such as ROS, MoveIt, Gazebo, and MuJoCo, making it suitable for embodied-AI experimentation and algorithm development.

Record changelog
- Weight: 32.7 kg changed to 8 kg net weight · Jul 9, 2026
tranche-7 verification (corrected): Maker spec: Net Weight 8KG (also OpenELAB distributor listing). Stored 32.7 kg is ~4x and identical to the bogus figure on mercury-a1 — cross-record bleed.
- Height: 850 mm changed to 537 mm (product size 200 x 192.5 x 537 mm) · Jul 9, 2026
tranche-7 verification (corrected): Maker spec: 537 mm height. Stored 850 mm matches no maker figure (possibly a with-stand or wingspan number from an aggregator).
- Degrees of Freedom: 12 changed to 17 · Jul 9, 2026
tranche-7 verification (corrected): Maker spec page and GitBook both: 17 DOF (2x7-axis arms + head/waist axes). Stored 12 is wrong.
- Battery Life: 90 min changed to None (mains-powered, 24 V) · Jul 9, 2026
tranche-7 verification (corrected): ORIGINAL corrected_value: None — mains-powered (24 V working voltage); no onboard battery; recommend removing this row | Maker spec: working voltage 24 V, no batter
- Reach: 500 mm changed to 450 mm maximum working radius (per arm) · Jul 9, 2026
tranche-7 verification (corrected): Maker spec: maximum working radius 450 mm.
- Repeatability: ±0.5 mm changed to ±0.05 mm · Jul 9, 2026
tranche-7 verification (corrected): Maker spec: repeatability ±0.05 mm. Stored ±0.5 mm under-states precision by 10x (decimal-place error).
- Communication: WiFi, Ethernet changed to CAN Bus, WiFi, Ethernet (network port), Bluetooth, USB serial port · Jul 9, 2026
tranche-7 verification (corrected): Maker spec page: 'CAN Bus/WIFI/Network port/Bluetooth/USB serial port'. Stored value is true but incomplete — expand to the full maker list.
- Sensors: IMU, cameras changed to Orbbec Deeyea 3D camera + 4-microphone line array (5 m / 180° pickup); no IMU documented · Jul 9, 2026
tranche-7 verification (corrected): Maker spec page lists the 3D camera and microphone array; no IMU appears in any maker source for the B1.
- Locomotion: Bipedal changed to Stationary (fixed-base dual-arm torso; no legs or wheels) · Jul 9, 2026
tranche-7 verification (corrected): B1 is the 'Dual-Arm 7-DOF Semi-Humanoid' — a 537 mm bench-mounted torso. It has no locomotion; the mobile family member is the wheeled (not bipedal) Mercury X1. 'Bi
