R1-A5-D Ultimate F — mobile-base humanoid with LinkerBot O6 dexterous hands, wrist RGB cameras, MID360 LiDAR & stereo vision

What's in This Configuration

The R1-A5-D Ultimate F is built for researchers who need high-DOF dexterous manipulation on a mobile platform. It pairs the same R1-A5-D mobile base with LinkerBot O6 six-DOF dexterous hands and wrist-mounted RGB cameras — all driven by the NVIDIA Jetson Orin NX 100 TOPS compute module. Unlike the Smart series, Ultimate F runs on an 8-core CPU with 16 GB LPDDR5 and dual DLA cores — delivering 2.5× the AI performance and enough memory headroom for large-model inference, multi-modal sensor fusion, and real-time control of complex hand kinematics. The LinkerBot O6 hands provide five-finger dexterous grasping with 6 active degrees of freedom and 130 N grip force — enabling in-hand manipulation, precision grasping, and adaptive contact on the move.

LinkerBot O6 — Six-DOF Dexterity for Mobile Manipulation

The LinkerBot O6 is a five-finger dexterous hand with 6 active degrees of freedom distributed across 11 joints (6 active + 5 passive). Its worm-gear transmission delivers high torque density and holding stiffness — critical for mobile platforms where vibrations and accelerations would challenge weaker mechanisms. Each hand weighs only 370 g, minimizing payload burden on the R1-A5-D arms while delivering 130 N maximum five-finger grip force. The thumb generates 28 N tip force and the four fingers 33 N combined — enough for robust grasping of irregular, deformable, and delicate objects. With ±0.2 mm repeat positioning accuracy, the O6 enables precision tasks like tool insertion, connector mating, and in-hand reorientation. The passive joints provide adaptive compliance during contact, letting the hand conform to object geometry without explicit sensing — a key advantage for unstructured mobile environments.

Wrist-Mounted RGB Cameras — See From the Gripper

Ultimate F adds wrist-mounted RGB cameras to both arms — providing a gripper's-eye view of the workspace. These cameras capture close-up visual detail that the head-mounted stereo pair cannot: texture, surface geometry, and grasp point quality at the moment of contact. Combined with the LinkerBot O6's dexterity, wrist vision enables visual servoing for precision grasp alignment, grasp verification (did the fingers close on the target or miss?), and in-hand tracking (monitoring object pose during manipulation). The Orin NX 100 TOPS processes wrist streams alongside head vision and LiDAR — using DLA cores to offload perception networks while the GPU handles grasp planning and hand kinematics. This three-scale visual hierarchy (wrist detail → head scene → LiDAR surround) is unique to configurations with wrist cameras.

Vision-LiDAR-Wrist Fusion — Three-Scale Perception

Ultimate F processes three synchronized sensor modalities on the Orin NX 100 TOPS: scene-level depth from the head binocular camera, 360° point clouds from the MID360 LiDAR, and close-up RGB from the wrist-mounted cameras. The dual DLA cores run vision perception networks in parallel — one DLA for head stereo object detection, one for wrist grasp analysis — while the GPU handles LiDAR SLAM, path planning, and dexterous hand control. With 16 GB RAM, the system holds multiple perception models concurrently: a scene understanding network for navigation, an object detector for grasp targets, a wrist-based grasp quality estimator, and a hand kinematics solver — all running simultaneously without swapping. This three-scale fusion enables research in active perception (moving the hand to get a better view), dexterous mobile grasping (coordinating base motion with finger closure), and multi-modal embodied AI (learning policies that fuse LiDAR, head vision, and wrist vision into unified action).

Autonomous Mobile Base — Navigate, Then Manipulate

The R1-A5-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.

Orin NX 100 TOPS — Flagship Compute for Dexterous Manipulation

The built-in NVIDIA Jetson Orin NX delivers 100 TOPS of AI compute across an 8-core CPU, 16 GB LPDDR5, and dual NVDLA V2.0 accelerators. Controlling two LinkerBot O6 hands with 6 DOF each, processing three visual streams (head stereo + two wrist cameras), and running LiDAR SLAM simultaneously demands serious compute — and the Orin NX delivers. The dedicated DLA cores offload neural network inference from the GPU, leaving GPU resources free for sensor fusion, grasp planning, and real-time hand kinematics. The 16 GB RAM provides space for large dexterous manipulation models, VLA policies, and multi-robot coordination algorithms that would not fit on an 8 GB module. No external GPU server, no cloud dependency — just power on and deploy.

Binocular Vision & Scene 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 and wrist RGB cameras, the R1-A5-D Ultimate F offers a complete three-scale perception stack for dexterous mobile manipulation research — with the Orin NX 100 TOPS processing all streams in real time for SLAM, object detection, grasp planning, and hand control.

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-A5-D Ultimate F navigates standard doorways, elevators, and lab aisles. The telescopic pillar lowers the upper body for transport and raises it for manipulation. At approximately 30 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, and hollow internal wiring make the R1-A5-D Ultimate F a clean slate for reinforcement learning, dexterous manipulation research, embodied AI, and autonomous navigation studies. The built-in Orin NX 100 TOPS with dual DLA cores and 16 GB RAM handles perception, grasp planning, and hand control locally — with compute headroom to grow into tactile sensing, large VLA models, and multi-robot coordination without hardware limits.
