What's in This Configuration
The R1-A5 Smart A is the entry-level configuration of the R1-A5 platform. You get the full fixed-base dual-arm humanoid body with binocular vision, voice interaction, and open SDK — paired with the reliable Dex1-1 V2 two-finger parallel grippers for standard pick-and-place, grasping, and manipulation tasks. The built-in Orin Nano 40 TOPS compute module enables on-device deep learning, visual perception pipelines, and larger model inference right out of the box.
✓ 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.
✓ Dex1-1 V2 Parallel Grippers
Two-finger grippers on both arms. Reliable, fast, and perfect for standard grasping and pick-and-place operations.
✓ Orin Nano 40 TOPS
Onboard NVIDIA Jetson Orin Nano delivering 40 TOPS for real-time perception, SLAM, 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.
✓ Voice Interaction
4-array beamforming mics + dual 3 W speakers. Wake-word, multilingual TTS, LLM integration ready.
✓ Full-Stack Open SDK
Linux framework, ROS 2 native, open APIs for arms, audio, vision, lighting. Dual encoders per joint.
Dual-Arm Architecture. Human-Like Dexterity.
The R1-A5 Smart A is engineered around two 5-DOF high-performance arms, each driven by low-inertia inner-rotor PMSM motors with crossed-roller bearings. With 420 mm reach, 60 Nm peak shoulder torque, and a ~2 kg payload per arm, it handles precise assembly, pick-and-place, and manipulation research with human-like fluidity. Dual encoders on every joint deliver closed-loop precision down to ±0.1 mm.
Dual 5-DOF arms with Dex1-1 V2 parallel grippers for reliable pick-and-place and manipulation
Dex1-1 V2 Parallel Grippers — Reliable & Fast
The Dex1-1 V2 is a robust two-finger parallel gripper designed for speed and consistency. It excels at grasping regular-shaped objects, tools, and components in structured environments. While more advanced dexterous hands are available as upgrades, the Dex1-1 V2 provides everything a research lab needs to start collecting manipulation data immediately — at the lowest entry price in the R1 lineup.
Orin Nano 40 TOPS — AI Onboard, No Latency
Unlike the bare R1-A5 base model, Smart A ships with a built-in NVIDIA Jetson Orin Nano delivering 40 TOPS of AI compute. This means visual SLAM runs in real time, object detection models process frames locally, and reinforcement learning policies execute with sub-millisecond latency. No external GPU server, no cloud dependency — just plug in power and start training.
Binocular Vision & AI Perception
A binocular camera head delivers a 146° × 124° field of view with a 60 mm stereo baseline. RGB streams at 1280×720@30 Hz and depth at 544×448@10 Hz give the R1-A5 true spatial awareness. Paired with an 8-core high-performance CPU + 10 TOPS NPU in the head module, plus the Orin Nano 40 TOPS body compute, it runs visual SLAM, object detection, and gesture recognition locally — no cloud required.
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 A 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.
Compact 11 kg fixed-base design — deploy on any desk or lab bench
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 A a clean slate for reinforcement learning, teleoperation research, and embodied AI. The built-in Orin Nano 40 TOPS handles model training and inference without external hardware.
Upgrade Path — Grow With Your Research
Start with Smart A and expand as your projects evolve. The R1-A5 platform is fully modular:
- End Effectors — Upgrade from Dex1-1 V2 to Dex3-1 3-finger hand, BrainCo Revo 2 5-finger dexterous hand, or LinkerBot Hand O6 (tactile and non-tactile versions).
- 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.
