RobotEra Robotic Hands

RobotEra Robotic Hands

Anthropomorphic five-finger architecture

The flagship XHAND1 is described by RobotEra as a five-fingered robotic dexterous hand with 12 fully active degrees of freedom. The company says the thumb and index finger each have 3 DoF, while the remaining fingers each have 2 DoF. RobotEra also highlights index-finger lateral movement of ±15°, which it says enables tasks such as twisting bottle caps and more delicate manipulation.

Fully actuated, quasi-direct-drive philosophy

One of the defining design features of XHAND1 is RobotEra’s emphasis on full actuation and quasi-direct-drive transmission. The company states that, unlike some under-driven designs, XHAND1 uses full-gear quasi-direct-drive transmission with all active joints locally positioned and decoupled. RobotEra argues that this gives researchers “real freedom” for AI development, including imitation learning and reinforcement learning, while also improving impact resistance through backdrivability.

This is a meaningful design choice. In dexterous robotics, fully actuated joints typically make it easier to model motion precisely and to build algorithmic control pipelines without compensating for passive couplings. RobotEra’s framing shows that XHAND1 is intended not only as a practical robot hand, but also as a research-capable manipulation platform.

High-resolution tactile sensing

RobotEra says XHAND1 is equipped with a high-resolution tactile array sensor on each finger, with more than 100 sensing points per finger. The company states that these sensors provide three-dimensional force tactile information and temperature information. That is a notable feature because tactile sensing is still one of the major differentiators in advanced robotic-hand design.

In practice, tactile sensing can improve grip adjustment, object contact awareness, fragile-item handling, and data collection for embodied AI systems. RobotEra’s inclusion of finger-level tactile arrays shows that XHAND1 is meant for serious contact-rich interaction rather than only visual servoing.

XHAND Lite as the compact deployment hand

The second clearly visible public RobotEra hand is XHAND Lite, shown on the Q5 service-robot page. RobotEra describes it as 11 DoF, slim and elegant, and human-hand sized, with fast response up to 10 CPS and single-hand payload up to 10 kg. The page also says it is backdrivable compliant and uses miniature force-control joints for fingertip precision.

This suggests a different design priority from XHAND1. Where XHAND1 is the more fully documented flagship dexterous hand, XHAND Lite appears to be the more compact integration-ready hand for service robots and lighter humanoid platforms.

Technology and Specifications

XHAND1 technical profile

According to RobotEra’s official XHAND1 page, the hand has 12 independent degrees of freedom, five fingers, and ±15° lateral movement in the index finger. RobotEra also states that the hand supports a whole-hand grip strength of 80 N and that every joint can be back-driven, enabling current-loop force control thanks to high transparency and low damping.

The company further says that XHAND1 uses fully self-developed integrated joint modules featuring coreless motors, low damping reducers, and high-power-density actuators. This matters because it shows RobotEra is not only assembling an outer hand shell, but is publicly claiming in-house actuator and transmission design as part of the product’s technical identity.

Force control and teleoperation

RobotEra says XHAND1 supports current-loop direct force control, as well as joint-space and Cartesian-space impedance control. The company also highlights VR teleoperation based on finger visual tracking and EMG teleoperation based on forearm signals, showing that XHAND1 is intended to work in both embodied AI and human-in-the-loop control pipelines.

Those capabilities matter because dexterous robotic hands are increasingly used not only for autonomous grasping, but also for demonstration capture, telepresence, human skill transfer, and data generation. RobotEra’s official wording strongly positions XHAND1 in this modern manipulation-research landscape.

Software compatibility and development support

RobotEra states that XHAND1 supports Linux, C++, Python, and ROS, making it compatible with common robotics-development environments. That is a significant point for buyers and researchers because it indicates the hand is intended to be programmable and integrated into standard robotics software stacks rather than controlled only through proprietary closed tools.

XHAND Lite technical profile

The public technical details for XHAND Lite are more limited because it does not appear to have its own standalone full specification page in the reviewed RobotEra materials. Still, RobotEra directly states that XHAND Lite has 11 DoF, 10 CPS response speed, 10 kg single-hand payload, backdrivable compliance, and miniature force-control joints. Those are the core public specifications that can be confidently attributed to the Lite version.

Integration with RobotEra platforms

RobotEra’s L7 page states that the humanoid can be equipped with XHAND1, described there as a fully direct-driven, 12 active DoF, humanoid five-finger dexterous hand. The Q5 page presents XHAND Lite in a service-robot context with a 7-DoF anthropomorphic robotic arm and a 1380 mm reach. This shows that RobotEra’s robotic hands are not standalone products only, but are already integrated into the company’s larger humanoid and service-robot systems.

Applications and Use Cases

RobotEra’s public materials strongly suggest that its robotic hands are intended for humanoid robotics, service robotics, and embodied AI research. On the L7 page, XHAND1 is associated with full-size humanoid applications such as intelligent sorting, intelligent handling, intelligent scanning, intelligent assembly, and data collection. Those use cases imply industrial and research tasks requiring coordinated reach, object interaction, and human-like handling capability.

On the Q5 page, XHAND Lite is shown in a more service-oriented role. RobotEra lists Q5 application areas including shopping mall guidance, tourism interpretation, home services, customer service, health care, and education. In these contexts, a robotic hand needs to support gestures, light object handling, human-facing interaction, and mobile assistance rather than heavy industrial manipulation.

XHAND1 is also clearly relevant to robotics research. The official XHAND1 page explicitly discusses imitation learning, reinforcement learning, tactile sensing, force control, and teleoperation, all of which are central to current manipulation and embodied-intelligence research. For labs and advanced robotics teams, this makes XHAND1 a hand platform for data generation and algorithm development, not just an end-effector for finished products.

Advantages / Benefits

One of the biggest advantages of RobotEra robotic hands is their anthropomorphic manipulation focus. RobotEra is not presenting a simple industrial clamp or lightweight gesture hand. Both XHAND1 and XHAND Lite are described in terms of multi-finger dexterity, force control, and humanoid compatibility, which makes them better suited to human-oriented environments and more varied manipulation tasks.

A second major advantage is family segmentation. XHAND1 appears to be the more advanced, research-grade dexterous hand with tactile arrays, richer control modes, and deeper public documentation. XHAND Lite appears to be the compact, faster-response, deployment-ready hand for service and lighter humanoid systems. This separation allows RobotEra to serve more than one robot-hand use case without forcing every customer into the same hardware complexity level.

A third advantage is ecosystem integration. Because RobotEra already uses these hands inside its own platforms, buyers are not evaluating isolated components without system context. XHAND1 is already connected to the L7 humanoid story, and XHAND Lite is already tied to Q5. That gives the hands stronger practical relevance than a lab prototype with no public deployment path.
