What's in This Configuration
The R1-A5 Smart B upgrades the entry-level platform with Dex3-1 three-finger dexterous hands — each equipped with a wrist-mounted RGB camera for close-up visual feedback during grasping. Combined with the built-in Orin Nano 40 TOPS, this configuration is purpose-built for researchers exploring in-hand manipulation, visual servoing, and adaptive grasping algorithms.
✓ R1-A5 Fixed Base Body
Full upper-body humanoid: dual 5-DOF arms, 1-DOF waist, 2-DOF head. 700 × 357 × 190 mm, ~11 kg.
✓ Dex3-1 3-Finger Hands
Three-finger dexterous hands on both arms with independent finger control for adaptive grasping and in-hand manipulation.
✓ Wrist RGB Cameras
Dedicated RGB cameras mounted on each wrist for close-range visual feedback, pose estimation, and grasp verification.
✓ Orin Nano 40 TOPS
Onboard NVIDIA Jetson Orin Nano delivering 40 TOPS for real-time perception, visual servoing, and AI model inference.
✓ Binocular Vision Head
RGB 1280×720@30 Hz + Depth 544×448@10 Hz. 146°×124° FOV, 60 mm baseline. 8-core CPU + 10 TOPS NPU on-board.
✓ Full-Stack Open SDK
Linux framework, ROS 2 native, open APIs for arms, audio, vision, lighting. Dual encoders per joint.
Dex3-1 — Three-Finger Dexterity with Visual Feedback
The Dex3-1 is a research-grade three-finger dexterous hand designed for adaptive grasping and precision manipulation. Each finger operates independently with multiple joints, enabling power grasps, pinch grasps, and in-hand reorientation of objects. The integrated wrist RGB camera provides a dedicated close-up view of the gripper workspace — critical for visual servoing, grasp pose estimation, and verification loops in autonomous manipulation pipelines.

Wrist-Mounted RGB Cameras — See What You Grasp
Each Dex3-1 hand carries a dedicated RGB camera at the wrist, streaming high-resolution video of the gripper's immediate workspace. This dual vantage point — head binocular vision for scene understanding plus wrist cameras for grasp detail — enables multi-scale perception pipelines. Researchers can implement visual servoing, track object deformation during grasp, and verify successful contact before releasing — all with minimal latency thanks to the onboard Orin Nano 40 TOPS.
Orin Nano 40 TOPS — AI Compute for Real-Time Manipulation
The built-in NVIDIA Jetson Orin Nano delivers 40 TOPS of AI compute, handling simultaneous streams from the head binocular camera and both wrist RGB cameras. Run visual SLAM, grasp pose detection, and reinforcement learning policies locally with sub-millisecond latency. No external GPU server, no cloud dependency — just plug in power and start training.
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. Combined with the wrist RGB cameras on each Dex3-1 hand, the R1-A5 Smart B offers a complete multi-camera perception stack for research in visual manipulation, active perception, and hand-eye coordination.
Voice Collaboration & Natural Interaction
Four-array beamforming microphones and dual 3 W speakers enable clear voice capture and synthesis in noisy labs or classrooms. The open audio framework supports custom wake words, multilingual TTS, and integration with LLMs for conversational command-and-control.
Compact. Lightweight. Desk-Ready.
At just 700 × 357 × 190 mm and approximately 11 kg, the R1-A5 Smart B fits on a standard lab bench or classroom desk. The fixed-base design eliminates footprint concerns while delivering full upper-body humanoid kinematics. Power via the included external supply — an optional upper-body Li-ion battery is available for ~1.5 hours of untethered operation.

Full-Stack Open Development
Unitree provides a mature, Linux-based robot development framework with open APIs for the underlying system, robotic arms, audio, lighting, and visual control. ROS 2 native support, dual encoders on every arm joint, and hollow internal wiring make the R1-A5 Smart B a clean slate for reinforcement learning, teleoperation research, and embodied AI. The built-in Orin Nano 40 TOPS handles model training and inference for multi-camera perception pipelines without external hardware.
Upgrade Path — Grow With Your Research
Start with Smart B and expand as your projects evolve. The R1-A5 platform is fully modular:
- End Effectors — Upgrade to Dex3-1 Tactile for force feedback, BrainCo Revo 2 5-finger hand for anthropomorphic grasping, or LinkerBot Hand O6 for 6-DOF dexterity.
- Upper-Body Battery — Add the Li-ion battery pack for ~1.5 hours of cord-free operation.
- Mobile Base — Upgrade to the R1-A5-D platform with wheeled autonomous chassis, LiDAR, and expanded workspace.
