R1-A5-D Ultimate E — mobile-base humanoid with BrainCo Revo 2 Tactile five-finger hands, wrist RGB cameras, MID360 LiDAR & stereo vision

What's in This Configuration

The R1-A5-D Ultimate E adds integrated tactile sensing to the BrainCo Revo 2 five-finger anthropomorphic hands — combining force-sensitive fingertips and palm arrays with the human-like hand form factor, wrist RGB cameras, and the NVIDIA Jetson Orin NX 100 TOPS compute module. Each hand features five independently actuated fingers (thumb, index, middle, ring, pinky) with a thumb-opposable architecture that mirrors human hand kinematics, now augmented with real-time pressure mapping and contact detection. This transforms the BrainCo Revo 2 from a visually-guided anthropomorphic manipulator into a touch-aware human-like hand — enabling force-controlled grasping, slip detection, and compliant interaction with fragile objects while navigating. With 16 GB RAM and dual DLA cores, the Orin NX fuses tactile pressure maps, wrist-camera RGB, head stereo depth, and MID360 LiDAR point clouds in real time — the most complete multi-modal perception pipeline in the R1-A5-D lineup.

BrainCo Revo 2 Tactile — Five Fingers That Feel

The BrainCo Revo 2 Tactile takes the five-finger anthropomorphic architecture of the Basic model and adds force-sensitive tactile sensors integrated into the fingertips and palm surfaces of each hand. These sensors deliver real-time pressure maps, contact location data, and slip detection across all five fingers — enabling the hand to feel what it grasps, not just see it. On a mobile platform, this is transformative: the robot can detect when a five-finger grasp is unstable during transport, modulate grip force to avoid crushing fragile objects while navigating, use tactile feedback to complete grasps in visually occluded environments, and execute compliant interaction strategies that require simultaneous force and position control. The tactile stream runs at high frequency into the Orin NX 100 TOPS, where it fuses with wrist-camera RGB, head stereo depth, and LiDAR point clouds for the most complete multi-modal perception pipeline available on a mobile humanoid.

Tactile Anthropomorphic Grasping — The Best of Both Worlds

Ultimate E is the only R1-A5-D configuration to unite five-finger anthropomorphic form with integrated tactile sensing on a mobile base. The BrainCo Revo 2 Tactile hands can execute the full GRASP taxonomy — from precision pinches to power grips — while simultaneously sensing contact forces to prevent damage and adapt grip strength in real time. The robot can grasp a wine glass with a tripod-plus-two-fingers configuration, feel when the grip is secure, and transport it safely while navigating around obstacles. It can pick up a tool, sense the handle texture and weight distribution through the fingers, and use the tool with force-aware control. The wrist RGB cameras provide visual verification of finger placement, while the tactile sensors report what the fingers cannot see. Combined with the head stereo camera for scene understanding and MID360 LiDAR for safe navigation, Ultimate E closes the loop between human-like dexterity, touch, and autonomous mobility.

Tactile-Visual-LiDAR Fusion — Five Modality Perception

Ultimate E processes synchronized streams from five sensor modalities on the Orin NX 100 TOPS: tactile pressure maps from each BrainCo Revo 2 Tactile hand, close-up RGB from wrist cameras, scene-level depth from the head binocular camera, 360° point clouds from the MID360 LiDAR, and proprioceptive data from dual encoders on every joint. The dual DLA cores run vision and tactile processing networks in parallel while the GPU handles multi-modal fusion and SLAM — no resource contention even under full load. With 16 GB RAM, the system can hold multiple models simultaneously: a tactile slip detector, a wrist-camera grasp verifier, a head-camera scene parser, a LiDAR localization network, and a tactile-visual-LiDAR fusion policy. This five-modality perception enables research in tactile anthropomorphic mobile manipulation, multi-modal sensorimotor learning, physical human-robot interaction, compliant grasping with force feedback while navigating, and embodied AI where human-like touch, vision, and spatial awareness converge.

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 Entry-Level 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. With BrainCo Revo 2 Tactile five-finger hands, wrist cameras, and multi-modal sensor fusion, this compute headroom enables the most advanced anthropomorphic mobile manipulation in the R1-A5-D lineup: run real-time SLAM with MID360 LiDAR, process stereo depth, wrist-camera, and high-frequency tactile streams simultaneously, deploy learned grasp policies with force feedback for five-finger configurations, and experiment with tactile sensorimotor learning — all at once. The dedicated DLA cores offload vision and tactile networks from the GPU, leaving GPU resources free for multi-modal fusion, hand-pose estimation, and compliant grasp planning. The 16 GB RAM provides space for large models 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, wrist-mounted RGB cameras, and tactile sensor arrays on each BrainCo Revo 2 Tactile hand, the R1-A5-D Ultimate E offers the most complete perception stack for tactile anthropomorphic mobile manipulation research — with the Orin NX 100 TOPS processing all five sensor modalities concurrently via DLA-accelerated networks.

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 E 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, visual control, and tactile sensing. ROS 2 native support, dual encoders on every arm joint, and hollow internal wiring make the R1-A5-D Ultimate E a clean slate for reinforcement learning, tactile anthropomorphic mobile manipulation research, embodied AI, and multi-modal sensorimotor learning. The built-in Orin NX 100 TOPS with dual DLA cores and 16 GB RAM handles tactile-visual-LiDAR fusion, five-finger grasp planning with force feedback, and compliant control locally — with compute headroom for larger models and multi-robot coordination without hardware limits.
