Search and rescue operations are time and labour intensive

It took just 3 minutes for this condo in Florida to collapse, killing close to 100 people, yet recovering all the victims took more than one month.

What if we could use technology to improve search and rescue processes and save more lives?

Gaps in current solutions

Complex

High-tech search and rescue devices require expertise to interpret sensor data received in determining presence of survivors.

Unreliable

Effectiveness of current solutions, such as search and rescue dogs, can be affected by weather or terrain conditions.

Manual

Existing search and rescue devices can be heavy and bulky which may pose an additional danger to rescuers.

How SLEEK Saves Lives

Sleek Movement

SLEEK is a soft robot powered by air pressure for pneumatic actuation, allowing it to navigate tight spaces within rubble.

A steering-reeling mechanism (SRM) is used for extending, retracting and changing direction when operating the robot.

Our robot achieves:

Life-sensing

An artificial intelligence-based sensor system mounted on the robot hears, smells, and searches for the presence of trapped survivors through the use of a microphone, CO2, and infrared camera data.

Intuitive Operator Interface

The operator interface allows users to view SLEEK's live camera feed, sensor data retrieved from within the rubble environment, as well as control SLEEK using a physical controller.

Semi-autonomous robot control

A human search protocol is built within SLEEK to assist users by providing them with navigational guidance - highlighting the direction with highest probability of human survivors.
