The Mercury B1 is a dual-arm semi-humanoid robot developed by Elephant Robotics. Equipped with two 7-axis robotic arms (based on the Mercury A1 architecture) and additional body articulation, it offers a total of 17 Degrees of Freedom (DOF).
Designed for embodied AI research, teleoperation, commercial service automation, and robotics education, Mercury B1 features a 9-inch high-definition LCD touch screen head for custom facial expressions, a built-in linear microphone array for LLM voice interaction, and full support for real-time exoskeleton and VR teleoperation.
Key Applications and Functions
- Embodied AI and Motion Data Collection: Serves as a primary hardware platform for training AI policies, imitation learning, and motion cloning via direct human teleoperation.
- Exoskeleton and VR Teleoperation: Pairs seamlessly with the myController S570 wearable exoskeleton for 1:1 motion replication or VR setups for real-time remote control in hazardous environments.
- Commercial and Service Tasks: Capable of complex, dual-arm coordinated operations such as coffee brewing, laboratory sample handling, 3D SLAM mapping, and interactive reception work.
- AI Voice Interaction: Integrates high-definition linear microphone arrays and LLM/ChatGPT integration for natural, real-time voice processing and multimodal machine intelligence.
Technical Specifications and Parameters
- Degrees of Freedom (DOF): 17 total (Dual 7-DOF Arms + Head/Body joints)
- Joint Modules: Powered by self-developed "Power Spring" Harmonic Modules
- Encoders: 19-bit high-resolution joint encoders
- Structure & Shell Material: Lightweight carbon fiber composite body for optimal strength and agility
