Inspire Dexterous Right Hand With Tactile Sensors (RH56F1-E2R-T1)

A robot hand is judged at the moment it touches something. Until that instant, a camera and a planner do all the work; after it, the hand has to feel what is happening and answer within milliseconds. The Inspire Dexterous Right Hand With Tactile Sensors (RH56F1-E2R-T1) is built around that moment: a right-hand, five-finger, all-metal end-effector with tactile sensing in the palm and a 1 kHz communication rate for real-time control.

The product is available through this page, by quotation.

Background

The company and the RH56F1 family

INSPIRE ROBOTS builds dexterous hands and grippers for robotics researchers, integrators and humanoid developers. The RH56F1 is one family within that range, offered as a left hand and a right hand, with or without tactile sensors, and with different communication pairings. The family comes in four versions: Left with EtherCAT and RS485, Left with EtherCAT and CAN FD, Right with EtherCAT and RS485, and Right with EtherCAT and CAN FD.

Within the same lineup you will find the plain right hand, the Inspire Robots Dexterous Right Hand (RH56F1-E2R), and the mirrored left hand with tactile sensors. Other hands from the maker are gathered in the Inspire Robots category.

Positioning and key technology

This is an all-metal tactile robotic hand for real-time EtherCAT control and repeatable manipulation research. Three ideas carry that description. The first is the metal body, which has a 30 kg static passive load capacity. The second is the tactile layer: 8 palm tactile sensors with a 30N range and an accuracy of 5% FS. The third is the control link, which runs at 1 kHz.

The hand offers 6 DOF across 12 joints. That is fewer actuated axes than a full human hand, but enough to shape a power grasp, a pinch and a hook, which covers a large share of what laboratories ask a hand to do. It is listed in the Robot Hands category alongside other dexterous options.

What makes the tactile version different from the plain right hand?

The difference is what the hand can tell your controller. The plain right hand, the RH56F1-E2R, moves and grips. The T1 version adds 8 palm tactile sensors with a 30N range, so the hand reports contact on the palm rather than leaving the controller to infer it. With an accuracy of 5% FS and a force resolution of 0.1 N, the signal is fine enough to separate a light touch from a firm press.

That matters in research. A learning policy that sees only joint positions has to guess whether an object is held. A policy that also reads palm contact can check it. The tactile version weighs 630 g ±10 g with tactile sensing included, so the sensing is part of the weight of the hand rather than an add-on you carry separately.

Why does the 1 kHz communication rate matter?

Touch is only useful if it arrives in time. At 1 kHz, the hand exchanges data with the controller every millisecond, which suits control loops that react to contact as it develops. EtherCAT is the real-time fieldbus this hand is built for. The Right / EtherCAT + RS485 version shown in the table above also carries RS485, and a separate Right version pairs EtherCAT with CAN FD. When you request a quotation, tell us which bus your controller speaks so that the right version is offered.

The hand also acts quickly: it closes in 0.8 s or less, with fingertip force of 15 N or more at the thumb and 10 N or more at the fingers. Repeatability is ±0.2 mm, which is what makes a trial run on Monday comparable with one on Friday.

Who is the Inspire Dexterous Right Hand With Tactile Sensors (RH56F1-E2R-T1) for?

University and institute laboratories are the clearest match. The hand is built for repeatable manipulation research, and the combination of tactile data, a fast bus and a durable metal body suits groups that run many trials and cannot afford a hand that wears out between experiments. It was verified through 20 standardized durability tests.

Humanoid and mobile-manipulation developers are a second group. A right hand with palm sensing gives a platform a way to confirm that it has an object before it lifts. Integrators building demonstration cells or teleoperation rigs will also find it useful, since the hand arrives as a self-contained unit with an operating voltage of 24V-48V.

If your work needs a hand without the sensing layer, the RH56F1-E2R is the sibling to look at. If your platform needs a left hand with tactile sensing, see the RH56F1-E2L-T1. Pairing a left and a right tactile hand is the natural route for bimanual work.

What is the Inspire Dexterous Right Hand With Tactile Sensors (RH56F1-E2R-T1) used for?

1. Manipulation research. Repeatable grasping and in-hand experiments where a position tolerance of ±0.2 mm keeps results comparable.
2. Tactile learning. Collecting palm contact data to train or test policies that depend on touch.
3. Humanoid platforms. Giving a humanoid or dual-arm robot a right hand that can hold and report contact.
4. Teleoperation. Mapping an operator's grasp to the hand, with force and contact readings returned over the fast bus.
5. Gripping trials. Testing how objects of different shapes are held using the 6 DOF across 12 joints.
6. Teaching and demonstration. Showing students and visitors what dexterous, touch-aware manipulation looks like on real hardware.

Pricing and Availability

This page does not print prices. A quotation is the way to proceed: tell us the version you need, the bus your controller uses and the quantity, and we will respond with an offer. Delivery, customs and support are arranged together with the quotation. The hand is supplied as one RH56F1 in the ordered configuration; mounting adapters, controller, power supply and cables are not promised unless they are itemized in the order. Requests for the RH56F1-E2R-T1 are handled and the hand is available on this page.

Summary

The RH56F1-E2R-T1 is a hand made for the moment of contact: a metal body that takes load, 8 palm sensors that report what they feel, and a 1 kHz link that carries that information to the controller without delay. For laboratories and developers who want a right hand that can both grip and sense, it is a focused choice, and the sibling hands cover the other cases.
