Tensegrity

Deployable Sensor for Disaster Area for Daniel Lim

Tensegrity sensor for disaster sites, which could be dropped from the sky (drone) to collect data for emergency response crews to examine crucial data such as gas leakage, images, and audios from survivors. Due to the risk, this deployable sensor is especially beneficial when it comes to unapproachable sites by humans. Multiple tensegrity modules stored in a basket under the drone with an automated deployment system are deployed on multiple sites nearby to the region of interest once the drone arrives at the location.

Unique Properties

Tensegrity sensor for disaster site, which could be dropped from the sky (drone) to gather information for the emergencyresponse crew (gas leaks, visuals, and audios). Once the drone arrives at the spot, many tensegrity modulesstored in a basket with an autonomous deployment system are deployed on multiple locations. The sensors can be delivered to disaster areas where humans are unable to approach.

Production Technology

The tensegrity module's goal is to offer the response team in a catastrophe region with a range of data. This data contains auditory or visual alerts that may have been generated by survivors, as well as a collection of gas leaks that may have enabled focused response to prevent larger accidents. Enclosures for the current mudules are made with SLA 3D printing, and many wireless sensors are enclosed. Furthermore, commercial nylon threads were employed to give the necessary tension for the framework.

Design Challenge

Finding appropriate materials for the string was extremely difficult because it needed to offer enough tension as well as strength to endure the drop. Another challenge was the module's assembly, which required many stiff rods to be linked at the same time. We solved this problem by creating a 3D printed jig that holds the component in place during assembly and using nylon threads to give sturdiness as well as enough tension for the construction.

Project Duration

The project started in August 2021 in Seoul, Korea and finished in March 2022 in Berkeley, California.

Operation Flow

Initially, four sensor modules are carried in a collapsed hexagonal box attached to the drone. When the drone approaches the point of interest (to collect data), the bottom panel of the box opens, allowing the sensor module to be dropped from a great height. The module rapidly deploys into the fully tensioned tensegrity structure, absorbing enough energy from impact with the ground. The module collects data for the reaction strategy by deploying various sensors.

Research

This design is based on the tensegrity structure, which has sparked academic interest due to its energy absorption qualities with a specially constructed mix of rigid rod and strings. Through interviews and observations, we discovered that the quick reaction team frequently lacks the data required for the response plan, particularly in the case of a large-scale disaster such as a forest fire. Because drones have limited battery life and require pilot control to gather information, we developed tensegrity modules that can be easily deployed to many places in need of sensory input.

Inspiration

Tensegrity structures are a type of stiff beam coupled with many strings that generate tension that can sustain the impact of a collision. Inspired by the structure, the sensor can be deployed from more than 50 m above the ground without the use of an additional device (parachute).

Project Overview

Tensegrity Deployable Sensor for Disaster Area has been a Platinum winner in the Product Engineering and Technical Design award category in the year 2021 organized by the prestigious A' Design Award & Competition.
