BrainCo Revo 2 Basic — Five-Finger Anthropomorphic Dexterity

The BrainCo Revo 2 Basic is a five-finger anthropomorphic dexterous hand designed to replicate the kinematic structure and grasp repertoire of the human hand. Each of the five fingers is independently actuated with human-like joint architecture, enabling the full taxonomy of human grasps — from cylindrical power grips to lateral pinches and tripod precision holds. The anthropomorphic design makes the Revo 2 Basic ideal for research in human-robot interaction, imitation learning from human hand videos, and dexterous in-hand manipulation. Pre-installed on both 7-DOF arms, it turns the R1-A7-D into a mobile platform for studying human-like manipulation in real-world environments.

Anthropomorphic Grasping — Human-Like Dexterity at Your Desktop

Smart D brings human-like grasping capability to mobile robotics research. With five independently controlled fingers, the BrainCo Revo 2 Basic can execute power grips for heavy objects, precision grips for delicate items, tripod grasps for spherical objects, and lateral pinches for flat surfaces — the complete repertoire of human hand grasps. The hand supports in-hand manipulation: reorienting objects without releasing them, sliding fingers along surfaces, and adjusting grip configurations mid-task. This level of dexterity opens research avenues in human-robot handover, tool use, and complex bimanual tasks that require fine finger coordination.

Five-finger anthropomorphic grasping — power grips, precision holds, and in-hand manipulation

Vision-Wrist Fusion — Two-Scale Perception for Anthropomorphic Manipulation

Smart D processes visual data from two complementary viewpoints: the head-mounted binocular camera provides global scene understanding and object localisation, while the wrist-mounted RGB cameras offer local, hand-centric views for grasp pose estimation and finger tracking. This vision-wrist fusion is particularly powerful for anthropomorphic hands: the wrist camera can track individual fingertip positions, monitor grasp quality, and detect object slip from visual cues — all while the head camera maintains awareness of the broader workspace. Fused on the Orin Nano 40 TOPS, this dual-view architecture supports research in visual imitation learning from human hand videos, grasp pose estimation for five-finger grasps, and closed-loop anthropomorphic manipulation.

7-DOF Arms — Human-Like Redundancy & Reach

The R1-A7-D features seven degrees of freedom per arm — matching the kinematic complexity of the human upper limb. With a 555 mm reach (forearm + upper arm) and 120 Nm peak shoulder torque, these arms can reach around obstacles, maintain orientation while translating the end effector, and execute complex trajectories impossible for simpler 5- or 6-DOF manipulators. Crossed-roller and double-row ball bearings on every joint ensure smooth, precise motion with minimal backlash. Dual encoders per joint provide closed-loop accuracy for research-grade repeatability.

Autonomous Mobile Base — Navigate, Then Manipulate

The R1-A7-D chassis adds 3 degrees of freedom to the upper body: a telescopic pillar for height adjustment and a 2-DOF wheeled base for omnidirectional navigation. Combined with the MID360 LiDAR and stereo camera head, the robot builds real-time maps, plans paths, and avoids obstacles autonomously — then stops precisely to manipulate. The removable lithium-ion battery in the chassis delivers approximately 1.5 hours of untethered operation. Please note: the upper body of this model does not accept a battery.

LiDAR + Stereo Vision — Complete Perception Stack

Smart A processes data from two complementary sensors: a MID360 360° LiDAR for metrically accurate mapping and long-range obstacle detection, and a binocular camera head (146°×124° FOV, 60 mm baseline) for colour vision, object recognition, and depth estimation. Fused on the Orin Nano 40 TOPS, this dual-modality perception stack supports research in visual-LiDAR SLAM, semantic navigation, and active perception for mobile manipulation.

Orin Nano 40 TOPS — Onboard AI for Navigation & Control

The built-in NVIDIA Jetson Orin Nano delivers 40 TOPS of AI compute, running SLAM, path planning, object detection, and arm trajectory generation locally. No external GPU server, no cloud dependency — just power on and deploy. The module is pre-installed and thermally integrated with the chassis cooling system. Optional 40 or 100 TOPS compute expansion modules are available for future upgrades.

Binocular Vision & Multi-Camera Perception

A binocular camera head delivers a 146° × 124° field of view with a 60 mm stereo baseline for scene-level understanding. RGB streams at 1280×720@30 Hz and depth at 544×448@10 Hz. Wrist-mounted RGB cameras on both arms add close-up visual feedback for grasp pose estimation and finger tracking. Combined with the MID360 LiDAR, the R1-A7-D Smart D offers a complete perception stack for research in visual-LiDAR fusion, semantic navigation, and anthropomorphic mobile manipulation.

Voice Collaboration & Natural Interaction

Four-array beamforming microphones and dual 3 W speakers enable clear voice capture and synthesis in noisy labs, warehouses, or classrooms. The open audio framework supports custom wake words, multilingual TTS, and integration with LLMs for conversational command-and-control — even while the base is in motion.

Collapsible. Mobile. Ready to Deploy.

At 683 × 520 × 440 mm collapsed (1323 mm elevated), the R1-A7-D Smart A navigates standard doorways, elevators, and lab aisles. The telescopic pillar lowers the upper body for transport and raises it for manipulation. At approximately 32 kg with battery, it is a self-contained mobile research platform — no external compute rack, no tether cables during operation.

Full-Stack Open Development

Unitree provides a mature, Linux-based robot development framework with open APIs for the underlying system, robotic arms, mobile base, audio, lighting, and visual control. ROS 2 native support, dual encoders on every arm joint, hollow internal wiring, and low-inertia, high-speed inner-rotor permanent magnet synchronous motors make the R1-A7-D Smart A a clean slate for reinforcement learning, mobile manipulation research, embodied AI, and autonomous navigation studies. The built-in Orin Nano 40 TOPS handles perception and planning locally without external hardware.

Upgrade Path — Grow With Your Research

Smart A is the entry-level mobile configuration. Expand capability as your research evolves:

  • End Effectors — Upgrade to LinkerBot O6 or tendon-driven hands for high-DOF or biomimetic dexterity.
  • Tactile — Add force-sensitive fingertips and palm arrays to the BrainCo Revo 2 for contact-aware anthropomorphic manipulation (Revo 2 Tactile).
  • Compute Module — Swap to the 100 TOPS expansion for large-model inference and multi-robot coordination.
  • Large VLM — Deploy vision-language models for natural-language task specification and scene understanding.
