Robotera XHAND1 - Lite Elfin Hand (XHAND1-Lite)

Most robot arms can reach almost anywhere, yet the hand at the end is often what decides whether the task succeeds. On a compact humanoid the hand has to be small, light and quick, and it still has to close around real objects. The Robotera XHAND1 - Lite Elfin Hand (XHAND1-Lite) is built around that trade-off: a slim five-finger hand with eleven degrees of freedom, close to the size of an adult hand.

Background

RobotEra and the Elf Hand

RobotEra builds humanoid and service robots, and its range includes the Q5 wheeled service robot, the L7 bipedal humanoid, the M7 upper-body wheeled humanoid and the Star1 humanoid. A company that builds whole robots needs hands that suit them, and the XHAND1 family comes from that need. The Lite model carries the nickname "Elf Hand," and it fits: the hand is slim and agile, and it is meant to look and move in a lifelike way.

The XHAND1 family has three versions named in the sources: XHAND1, XHAND1 Lite and XHAND1 PRO. This page is about the Lite model only. Every figure below belongs to the XHAND1 Lite, and none of it should be read across to the other two versions. If you are comparing, you can look at the XHAND1 Dexterous Right Hand and the XHAND1 Dexterous Left Hand pages, and ask us to line the specifications up when you request a quotation.

Positioning: light, fast and lifelike

The Lite hand is described as a lightweight robotic hand of 730 grams with fast repeated motion and full thumb-to-finger opposition. The weight matters more than it first appears. Every gram at the wrist is a gram the arm, the shoulder and the whole platform must carry and control. A lighter hand leaves more margin for the rest of the robot.

Its size helps as well. The hand is close to that of an adult hand, so it fits naturally onto smaller humanoid platforms. RobotEra pairs it with its RobotEra Q5 Wheeled Humanoid Service Robot for tasks that call for both precision and a lifelike appearance. The Q5 stands 1650 mm tall, weighs 154 lbs and has 44 DoF, including the 11-DoF XHAND Lite for precise manipulation.

Its mechanical character is also worth noting. The five fingers work through eleven combined joints that blend active motors with flexible, passive movement. The joints stay backdrivable, meaning they can flex slightly under outside pressure instead of locking rigidly. For a hand that works near people, or that may bump into objects it did not expect, that give is a practical benefit.

What makes the XHAND1 Lite different from a rigid gripper?

A simple gripper opens and closes on one axis, which is enough for a fixed, repetitive job. The XHAND1 Lite is a different kind of tool. It has five fingers, eleven degrees of freedom and a thumb that can reach every other finger, so it can take on a wider set of grips than a two-jaw gripper can. That range is what a humanoid needs when it must handle everyday objects of different shapes.

Speed is the second difference. The hand opens and closes more than ten times per second, which matters for repeated motion, for demonstrations and for collecting data in which many grasp attempts are made in a short time. Despite its light weight, it performs demanding, repeated motion reliably, and RobotEra rates it for one million grasp cycles, so it holds up under constant daily use.

The third difference is compliance. Because the joints are backdrivable, the fingers can flex slightly under outside pressure instead of locking. A stiff hand that meets an unexpected obstacle pushes back with the full strength of its drive. A backdrivable one yields, and that is the design intent behind the way the joints are built.

Who is the XHAND1 Lite for?

The first buyer is the builder of a compact humanoid or service robot. If your platform is small and every gram at the wrist counts, a 730-gram hand close to the size of an adult hand is a sensible match. Teams working on similar platforms will recognize the case of the Q5, where the hand is part of a robot designed for precision and a lifelike look.

The second buyer is the research lab or university group. Manipulation research needs hardware that can repeat a motion many times without wearing out, and the one-million-cycle rating speaks to that. Research teams should ask about software support when they request a quotation.

The third buyer is the integrator or demonstration team that needs a robot to appear natural. A hand with five fingers and full thumb opposition looks and behaves like a hand, and that helps in service, reception and exhibition settings. If you need a left or right hand, or you want to compare against the other versions in the family, tell us about your project and we will confirm which suits it. You can also browse the wider Hands and Robot Hands categories.

What is the XHAND1 Lite used for?

1. Humanoid manipulation. Gives a compact humanoid a five-finger hand for general-purpose grasping.
2. Service robotics. Supports tasks where precision and a lifelike appearance both matter, as on the Q5 service robot.
3. Research on dexterity. Provides a platform for studying grasp types and thumb-to-finger opposition.
4. Repeated-motion testing. Suits work that needs fast, repeated opening and closing over long runs.
5. Compliant interaction. Backdrivable joints let the fingers flex under outside pressure rather than lock.
6. Demonstration and education. Shows students and visitors how a human-sized robotic hand moves and grips.

Frequently Asked Questions

How many degrees of freedom does the XHAND1 Lite have?

It has 11 degrees of freedom. The five fingers work through eleven combined joints, blending active motors with flexible, passive movement.

How big and how heavy is it?

The hand measures 209 mm × 84 mm × 32 mm and weighs 730 grams. Its size is close to that of an adult hand.

How fast does it move?

It opens and closes more than ten times per second. RobotEra rates it for one million grasp cycles.

Which robot is it used with?

RobotEra pairs it with its Q5 service robot. The Q5 has 44 DoF, including the 11-DoF XHAND Lite.

Does it come with an SDK, and what interface does it use?

Ask us about software, the interface and the control modes when you request your quotation, and we will answer for your project.

Can the thumb touch all the other fingers?

Yes. The thumb can reach every other finger, which supports a wide range of grips.

Where can I buy the XHAND1 Lite and what does it cost?

You can buy it through this page by requesting a quotation. We do not list a price here; the cost is given in the quotation, together with delivery, customs and support arrangements.

Summary

The question at the start was how to get a capable hand onto a small robot without weighing it down. The XHAND1 Lite answers with 730 grams, eleven degrees of freedom, a thumb that reaches every finger, repeated motion at more than ten cycles per second and backdrivable joints. If a lightweight, human-sized hand fits your platform, this page is the starting point.
