What's in This Configuration

The R1-A7-D Smart E represents the ultimate anthropomorphic tactile manipulation platform. It pairs the R1-A7-D autonomous mobile base — complete with 7-DOF arms, MID360 LiDAR, stereo vision, and a removable chassis battery — with BrainCo Revo 2 Tactile five-finger anthropomorphic hands, force-sensitive fingertip and palm arrays, and wrist-mounted RGB cameras. The built-in Orin Nano 40 TOPS fuses stereo vision, wrist cameras, and tactile streams from all five fingers in real time for the most advanced multi-modal manipulation research.

✓ R1-A7-D Mobile Base Body
Full upper-body humanoid on a wheeled autonomous chassis: dual 7-DOF arms, 1-DOF waist, 2-DOF head, 1-DOF pillar, 2-DOF base. 683×520×440 mm collapsed, ~32 kg with battery.

BrainCo Revo 2 Tactile — Five-Finger Anthropomorphic Dexterity That Feels

The BrainCo Revo 2 Tactile combines full anthropomorphic five-finger dexterity with force-sensitive tactile sensing at every fingertip and across both palms. Each of the five fingers retains independent actuation and human-like joint architecture, enabling the complete taxonomy of human grasps — now with real-time contact force feedback. The tactile arrays measure pressure distribution, detect slip, and enable dynamic grip modulation across all five digits, transforming the Revo 2 from a visually guided anthropomorphic hand into a contact-aware system that can handle fragile objects, explore surfaces by touch, and execute force-sensitive human-robot handover. Pre-installed on both 7-DOF arms, the Revo 2 Tactile makes the R1-A7-D the most capable mobile anthropomorphic manipulation platform available.

Tactile Anthropomorphic Grasping — Feeling What You Grasp

Smart E unites human-like dexterity with tactile awareness. The five-finger architecture executes the full human grasp taxonomy — power grips, precision holds, tripod grasps, lateral pinches — while the tactile arrays report exactly how hard and where the hand is touching. This fusion enables force-aware in-hand manipulation: reorienting objects without visual feedback by sensing pressure changes, detecting slip before it happens, and automatically modulating grip force for fragile or deformable items. The Orin Nano 40 TOPS processes tactile streams from all ten fingertips and both palms alongside visual data, running multi-modal control policies entirely onboard. Essential for research in physical human-robot interaction, tactile exploration, and advanced sensorimotor learning with human-like hands.

Tactile-Vision-Wrist Fusion — Three-Modal Perception for Anthropomorphic Manipulation

Smart E fuses three complementary sensing modalities on the Orin Nano 40 TOPS: the head-mounted binocular camera provides global scene understanding, the wrist-mounted RGB cameras deliver local visual feedback of finger-object interaction, and the tactile arrays report real-time contact forces from all five fingertips and both palms. This tactile-vision-wrist fusion creates an unprecedented multi-modal representation of anthropomorphic manipulation — enabling the robot to see an object, plan a human-like grasp, execute it with visual guidance, and refine grip force based on tactile feedback. All three streams are timestamp-synchronised and accessible through the open tactile API, supporting cutting-edge research in cross-modal perception, sensorimotor learning, and adaptive control with human-like hands.

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 and tactile sensor arrays on both arms add close-up visual and force feedback for multi-modal anthropomorphic grasping. Combined with the MID360 LiDAR, the R1-A7-D Smart E offers a complete three-modal perception stack for research in tactile-vision fusion, semantic navigation, and contact-aware 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.
