Simple, yet highly effective

Soft, pressure-sensitive AIRSKIN® pads use air as sensing medium to detect collisions, enabling a safe workspace where humans and robots can collaborate freely.

 

Highest safety rating

Certified according to EN/ISO 13849-1 (PL e, Category 3) and EN/IEC 62061 (SIL 3). Demonstrated and proven technology. In the field for 2.5 years.

 

For collaborative robots

Covers all collision, clamping and shearing risks of robot and tool according to ISO 10218 and ISO/TS 15066.

About AIRSKIN® 

AIRSKIN® is an add-on, modular safety solution to upgrade industrial robots and EoAT with pressure-sensitive sensors. An AIRSKIN® pad is a soft, thin, airtight skin over a flexible dampening structure with smart safety electronics.


The sensors and pads

Dual channel pressure sensors inside the hull detect pressure changes when the pad is deformed as the result of a contact anywhere on the pad surface. Each pad monitors correct operation by maintaining an internal overpressure of 400 pascal using an integrated piezo micro pump. All pads are connected in series and monitor each others presence every 4 ms.


Sensitibity

The skin's sensitivity is independent of the contact region (near TCP, near first axis), and AIRSKIN® is equally effective for robots of any size and payload.

AIRSKIN® functionality

AIRSKIN® is easy to install and connect. A support structure is mounted on the robot and the pads snap-on-to the support structure using magnetic holders.

Simple configuration

AIRSKIN® acts as an OSSD device and connects directly to the safety inputs of your robot controller, or a safety PLC, using 24V for power supply and signals. No further configuration is required.

Safe collisions

AIRSKIN is a certified safety device (EN/ISO 13849-1 PLe/Cat 3 and EN/IEC 62061 SIL 3) and will detect all collisions with the robot (free-space, clamping and shearing) and bring the robot to a halt. 

Pressure

To activate AIRSKIN, only 5N of force is needed. The soft, thick pads will dampen collisions, absorb collision energy and avoid any high local pressures (see force and pressure limits in the ISO/TS 15066).

Collaborative applications

AIRSKIN® enables ISO/TS 15066 compliant collaborative applications.

How to use AIRSKIN®

AIRSKIN® provides you with a highly efficient and safe collaborative application after you cover the collision hazards and set the the robots' speeds set accordingly.

Free-space collisions

Free-space collisions are safe even beyond 1 m/s, also for large robots. The soft AIRSKIN® absorbs energy and distributes contact forces, thus avoiding high local pressures contact area and affected body region.

Clamping/shearing collisions

For clamping/shearing collisions the robot’s stopping distance must be shorter than the thickness of the soft AIRSKIN®. Permissible speeds must be obtained by measuring contact forces occurring in the collision using an ISO/TS 15066 compliant measurement device.

High speed in most trajectories 

Selecting the robot’s speed according to the potential collision situation allows high speeds in most parts of the robot’s trajectories, and requires reduced speed only near hard obstacles, like walls or fixtures.

Features

Dual channel OSSD safety device

AIRSKIN® is a Cat3, PLe safety device which is easily connected via its 6 wires to any safe I/O of any robot controller.

Magnetic

The soft pads are locked in place with magnets. Electrical wiring is chained via our proprietary 6-pin IP54 magnetic plugs, providing additional safety as cables are easily disconnected.

Smart Modules

Each AIRSKIN® Pad monitors and regulates its internal air pressure (4 ms) and also communicates to all the other pads on the robot. Status is visually communicated via LED color codes.

Frequently
Asked Questions

  • Make sure your robot is ready for ISO/TS 15066, meaning safe position and speed monitoring. With KUKA robots the required feature is called Safe Operation.

  • Up to 15 AIRSKIN pads can be connected in a series. On larger robots, for example Cybertech, we use four lanes with 12 pads on each lane, grouping them into "gripper", "axis 4-6" and so on.

  • Permissible speeds are obtained from ISO/TS 15066 using a formula involving robot mass and payload weight.

  • As with any robot application a risk analysis is mandatory. With AIRSKIN® the procedure is the same as using a lightweight cobot: identify possible collision zones and measure force and pressure. Set the robot speed at this position to meet the threshold in the ISO/TS 15066.
