What's in This Configuration
The R1-A7-D Ultimate A is the high-performance entry point to the R1-A7-D Ultimate series. It pairs the R1-A7-D autonomous mobile base — complete with 7-DOF arms, MID360 LiDAR, stereo vision, and a removable chassis battery — with Dex1-1 V2 parallel grippers on both arms and the powerful NVIDIA Jetson Orin NX 100 TOPS compute module. With 2.5× the AI performance of the Smart series, the Ultimate A handles larger vision models, faster SLAM, and more complex planning algorithms — all while maintaining the same accessible, entry-level gripper configuration that makes it ideal for mobile manipulation research, education, and rapid prototyping.
✓ 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.
✓ Dex1-1 V2 Parallel Grippers
Reliable two-finger parallel grippers pre-installed on both arms for pick-and-place, tool handling, and foundational manipulation tasks.
✓ MID360 LiDAR
360° surround LiDAR integrated into the mobile chassis for real-time SLAM, obstacle avoidance, and autonomous navigation.
✓ Orin NX 100 TOPS
Built-in NVIDIA Jetson Orin NX delivering 100 TOPS — 2.5× the AI compute of the Smart series for larger models and faster inference.
✓ Full-Stack Open SDK
Linux framework, ROS 2 native, open APIs for arms, base, audio, vision, lighting. Dual encoders per joint.
Dex1-1 V2 — Reliable Parallel Gripping
The Dex1-1 V2 is a two-finger parallel gripper engineered for dependable, repeatable pick-and-place operations. Its simple yet robust design delivers consistent clamping force across a wide range of object sizes and geometries, making it the ideal starting point for mobile manipulation research. The V2 revision improves durability and response speed over the original Dex1-1, ensuring stable grasping even during fast arm motions or on a moving base. Pre-installed on both 7-DOF arms, the Dex1-1 V2 gives researchers a solid foundation for learning-based grasping, bin picking, tool use, and human-robot collaboration experiments without the complexity of multi-finger control.
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.
Orin NX 100 TOPS — 2.5× AI Performance for Advanced Research
The built-in NVIDIA Jetson Orin NX delivers 100 TOPS of AI compute — a 2.5× leap over the Smart series' 40 TOPS. This extra headroom enables the Ultimate A to run larger vision-language models for natural-language task specification, real-time multi-object detection and tracking at higher frame rates, denser occupancy mapping for navigation in cluttered environments, and more complex motion planning algorithms that exploit the 7-DOF arm redundancy. The Orin NX also accelerates simulation-to-reality training pipelines, allowing researchers to deploy learned policies with lower latency and higher throughput. Pre-installed and thermally integrated with the chassis cooling system, the module runs entirely onboard with no external GPU server or cloud dependency.
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
Ultimate 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 NX 100 TOPS, this dual-modality perception stack supports research in visual-LiDAR SLAM, semantic navigation, and active perception for mobile manipulation — all with significantly more computational headroom than the Smart series.
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 MID360 LiDAR, the R1-A7-D Ultimate A offers a complete perception stack for research in visual servoing, semantic navigation, and vision-guided manipulation. The Orin NX 100 TOPS enables running larger vision backbones and more sophisticated fusion algorithms entirely onboard.
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. The extra compute headroom of the Orin NX 100 TOPS allows running larger speech recognition and language models locally.
Collapsible. Mobile. Ready to Deploy.
At 683 × 520 × 440 mm collapsed (1323 mm elevated), the R1-A7-D Ultimate 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 Ultimate A a clean slate for reinforcement learning, mobile manipulation research, embodied AI, and autonomous navigation studies. The built-in Orin NX 100 TOPS handles perception and planning locally without external hardware, with enough headroom for large-model inference and multi-task learning.
Upgrade Path — Grow With Your Research
Ultimate A is the high-performance entry-level configuration with maximum compute. Expand capability as your research evolves:
- End Effectors — Upgrade to Dex3-1 three-finger hands for adaptive grasping, BrainCo Revo 2 for anthropomorphic dexterity, LinkerBot O6 for high-DOF manipulation, or tendon-driven hands for biomimetic compliance.
- Wrist Cameras — Add wrist-mounted RGB cameras for close-up visual feedback during manipulation.
- Tactile Sensing — Integrate force-sensitive tactile arrays for contact-aware grasping and multi-modal sensorimotor learning.
- Large VLM — Deploy vision-language models for natural-language task specification and scene understanding. The 100 TOPS Orin NX has the headroom to run larger VLMs than the 40 TOPS Smart series.
