Inspire EG2-4C Dexterous Robot Hand (EG2-4C)

Most robot hands are judged by how many fingers they have; the Inspire EG2-4C Dexterous Robot Hand (EG2-4C) asks a plainer question: how well can an end effector feel what it is holding, and what does it do when something goes wrong? Force-position dual control, power-off self-locking and drop detection are the answer built into it.

The product is available through this page, by quotation.

Background

The company and its lineage

INSPIRE ROBOTS builds robot hands and end effectors for people who need to put a dependable tool at the end of an arm. Its catalog runs from multi-finger dexterous hands to more compact electric hands intended for repeatable handling work. You can browse the wider range in the Inspire Robots brand section, or see comparable products in the Robot Hands category.

The EG2-4C sits in an EG2 series. The sources we work from name two versions of it, the EG2-4C2 and the EG2-4B2. The figures in this article belong to the EG2-4C2 version only. We do not carry figures for the EG2-4B2 here, and we do not lend one version's numbers to the other.

Positioning and key technology

The EG2-4C is positioned as an end effector for automated operations across several industries. It is equipped with force-position dual control, power-off self-locking and drop detection. Each of these three features answers a practical worry on a working cell.

Force-position dual control means the hand can be commanded by how far it moves and by how hard it holds. That matters when the object is delicate, or when parts vary a little from one to the next. Power-off self-locking means that if the supply is lost, the hand keeps its hold instead of letting go. Drop detection lets the system know when a grasped object has slipped away, so the program can react instead of carrying on with an empty hand.

The EG2-4C2 is a light unit, which helps on small arms and mobile platforms where every gram at the wrist counts. It runs from a DC 24V supply and has a protection level of IP40, so it belongs in clean, indoor work areas rather than wet or dusty ones.

What makes the EG2-4C different from a simple open-and-close gripper?

A basic gripper opens and closes, and that is the end of the story. The EG2-4C2 adds a controlled grip: the force range runs from 0 to 20N, and the force repeats to within ±1N. For a buyer, that repeatability is the figure to read first. It tells you that the same command should give nearly the same squeeze on the hundredth part as on the first, which is what makes handling of fragile or lightweight items workable.

The second difference is how it behaves when things go wrong. Power-off self-locking addresses a lost supply, and drop detection addresses a lost object. Neither is glamorous, but both are the kind of feature that decides whether a cell can run unattended for a shift or needs somebody standing by.

The third is energy use. The EG2-4C2 draws 30mA when idling and 200mA unloaded at DC 24V ±10%. That is useful to know when you size a power supply, especially on a mobile platform that runs from a battery and cannot afford to waste it.

How fast and how light is the EG2-4C2?

The EG2-4C2 reaches a maximum speed of 70mm/s and completes a full stroke closing in 1.3s. That is a measured, deliberate pace, suited to careful pick-and-place, laboratory handling and research work rather than to the highest-speed packing lines. If your cycle time is critical, set the closing time against your target before you order.

At 231g, the unit adds very little load at the wrist. A lighter end effector leaves more of an arm's rated capacity for the object itself and puts less strain on the joints. Payload is a point to raise when you request your quotation.

Who is the EG2-4C for?

The first group is integrators building small automated cells. They need a tool with predictable force, a plain DC 24V supply and built-in safeguards, and they value a hand that holds on when power fails.

The second group is university labs and research teams. Force control with a stated repeatability gives them something to build experiments on, whether the work is grasp studies, teaching by demonstration or mobile manipulation.

The third group is companies in light assembly, testing and inspection, where parts are small and need gentle but repeatable handling in a clean indoor area. Because the protection level is IP40, buyers whose work is wet, dusty or outdoors should discuss their conditions with us first.

If you are weighing this hand against a sibling, look at the Inspire EG2-4B Dexterous Robot Hand (EG2-4B), which sits in the same family. Buyers who want multi-finger dexterity rather than this style of end effector may prefer the Inspire RH56E2 Dexterous Robot Hand (RH56E2) or the Inspire RH56BFX Dexterous Robot Hand (RH56BFX).

What is the EG2-4C used for?

1. Pick-and-place handling. Moving small parts between trays, fixtures and machines with a controlled, repeatable grip.
2. Laboratory automation. Handling samples, containers and test pieces where gentle force and repeatable results matter.
3. Research and teaching. Giving students and researchers a force-controlled end effector for robotics experiments.
4. Mobile manipulation. Carrying a light hand on a mobile base, where low weight and modest current draw help.
5. Assembly and inspection cells. Presenting parts to cameras and gauges, and holding them steady during light assembly steps.
6. Multi-industry automation. Serving as a general-purpose end effector in cells where safe holding during a power loss is required.

Frequently Asked Questions

What grip force does the EG2-4C2 offer?

The EG2-4C2 offers a grip force of 0–20N, with a force repeatability of ±1N.

What power supply does it need?

It operates at DC 24V ±10%. It draws 30mA when idling and 200mA unloaded.

What happens if power is lost?

The hand has power-off self-locking, so it is designed to keep its hold when the supply is cut. It also has drop detection to flag a lost object.

How fast does it close?

A full stroke closing takes 1.3s, and the maximum speed is 70mm/s.

Is it protected against dust and water?

The protection level is IP40, which suits clean indoor work areas. Wet or dusty environments should be discussed with us before ordering.

Is a software package or SDK included?

Please raise software and what comes in the box when you request your quotation, and we will come back to you on both.

Where can I buy the EG2-4C and what does it cost?

You can request it through this page, by quotation. The cost depends on your project, and we give it in the quotation rather than on the page.

Summary

The EG2-4C is not trying to win on finger count. It is trying to hold well, repeat its force, keep its grip when power fails and tell you when it has dropped something. With a 0–20N grip force, ±1N repeatability, a weight of 231g and a DC 24V supply, the EG2-4C2 suits careful handling in clean, indoor cells.
