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

Not every grasping task needs five fingers and a wall of sensors. Sometimes the job is to close, hold, release and repeat, without fuss and without losing the part when something goes wrong. The Inspire EG2-4B Dexterous Robot Hand (EG2-4B) is built around that plain idea: a long stroke, controlled force, a serial link and a hold that survives a power cut.

The Inspire EG2-4B is available through this page, by quotation.

Background

Inspire Robots and the EG2 line

INSPIRE ROBOTS is known for robot hands, and the catalog spans several ranges. The multi-fingered RH56 family, such as the Inspire RH56E2 Dexterous Robot Hand (RH56E2), sits at one end. The EG2 line sits at the other and is aimed at straightforward, repeatable opening and closing.

The sources name three versions in this line: EG2-4B, EG2-4C and EG2-5C. This page covers the EG2-4B only. Every figure below belongs to the EG2-4B, and none is borrowed from a sibling.

Key technology and positioning

The EG2-4B uses an innovative linear mechanical linkage design. It pairs force control with position control, known as force-position dual control. The result is a large stroke in a light body, with power-off self-locking and drop detection added for safety. It is aimed at automated operations across multiple industries.

In practice, that makes it a sensible choice where a team wants dependable handling more than finger-by-finger dexterity. It is compact, it talks over RS485, and it runs from a 24-volt supply.

What makes the EG2-4B different from a multi-fingered hand?

A multi-fingered hand earns its place when the object is irregular, when the task needs in-hand manipulation, or when touch feedback matters. It also asks more of the integrator, with more joints to command and more to understand. The EG2-4B takes the opposite approach. Its linear linkage gives a 70mm full stroke, so one device can open wide enough for larger parts and close down on smaller ones.

The weight is 223g, which matters on any arm, because every gram at the wrist is a gram the arm has to carry and stop. The grip force runs from 0 to 15N with ±1N repeatability, so a light part can be held gently and the same hold can be repeated cycle after cycle. Positioning repeatability of ±0.50mm supports the same kind of consistency in where the jaws stop.

The three safety behaviors are worth a second look. Power-off self-locking means a lost supply does not automatically mean a dropped part. Drop detection lets the control side know when a held object has gone. Together with the force-position dual control, they suit unattended cells where a quiet failure would be costly.

How fast and how demanding is the EG2-4B in operation?

The maximum speed is 97mm/s, and a full-stroke close takes 0.85s. For benchtop work, laboratory handling and light assembly, that is a comfortable rhythm. The electrical side is modest: operating voltage is DC24V±10%, idling current is 30mA, unloaded current is 200mA and peak current is 0.70A. A shared 24-volt rail on a small robot cell can usually serve it without special planning, though your engineer should check the full load budget.

The protection level is IP40 and the recommended working temperature is 0-40℃. That points to clean, indoor, controlled surroundings such as a lab, a classroom or a workshop, and not to washdown or dusty outdoor duty.

Control runs over RS485, a serial link familiar to most automation engineers.

Who is the Inspire EG2-4B for?

Integrators building pick-and-place or machine-tending cells will find the stroke and the repeatability figures easy to design around. Universities and training centers can use it where students need a hand that behaves predictably and can be commanded over a standard serial bus. Research teams building mobile manipulators may value the low weight and the small current draw.

Manufacturers with light handling tasks across several product lines can also use it, since a single stroke range covers varied part sizes. If your task needs more than a two-state grasp, look at the wider Robot Hands category or the full Inspire Robots range. Buyers who want to compare within the same line can also review the Inspire EG2-4C Dexterous Robot Hand (EG2-4C). Remember that its figures are its own and are not interchangeable with those above.

What is the Inspire EG2-4B used for?

1. Pick-and-place handling: moving light parts between trays, fixtures and conveyors with a repeatable grip.
2. Machine tending: loading and unloading small workpieces in an indoor cell.
3. Laboratory automation: handling sample holders and small containers on a bench.
4. Education and training: teaching force and position control on a hand that is simple to command.
5. Research on mobile manipulators: giving a light arm an end effector that adds little weight.
6. Light assembly: holding and presenting components where grip force must stay consistent.

Frequently Asked Questions

What is the stroke of the Inspire EG2-4B?

The full stroke, both sides together, is 70mm. The full-stroke closing time is 0.85s.

How much grip force does it provide?

Grip force ranges from 0 to 15N, with force repeatability of ±1N. Positioning repeatability is ±0.50mm.

What happens if power is lost?

The EG2-4B has power-off self-locking, so it is designed to keep its hold when the supply is cut. It also includes drop detection.

How is it connected and powered?

The communication interface is RS485, and the operating voltage is DC24V±10%. Idling current is 30mA and peak current is 0.70A.

Is it suitable for dusty or wet areas?

The protection level is IP40, and the recommended working temperature is 0-40℃. That suits clean indoor use. Tell us about harsher conditions when you request a quotation.

Which versions exist in the EG2 line?

The sources name the EG2-4B, the EG2-4C and the EG2-5C. This page describes the EG2-4B only.

Summary

The Inspire EG2-4B Dexterous Robot Hand (EG2-4B) makes its case by doing a few things well, not by doing everything. It offers a 70mm stroke, 0-15N of controlled grip force, a 223g body, an RS485 link, and a hold that stays on when power does not. For teams whose tasks are about repeatable closing and releasing, that is often all the hand they need. To check the fit for your application and receive a quotation, this page is the starting point.
