The robot, dubbed RoBoa, sorts through trash following disasters as well as through tight locations like pipes or sewers.

To accomplish this, RoBoa relies on a growth-based locomotion system, which features a soft fabric tube that expands into environments while also reducing friction and eliminating the need for traction. The developers of the RoBa explained that this design enables the robot to move over sticky, dirty or gravel-filled terrains.

For now, RoBoa is capable of extending up to 328 ft in length. RoBoa can also be used in emergencies because it is equipped with a speaker and microphone, which allows the robot to communicate directly with victims.

Further, the robot is outfitted with data-collecting sensors, and it is comprised of soft materials for safe interaction with humans, while its pressurized air system reduces spark risks, thereby making it appropriate for explosive environments.

RoBoa also features a supply line that can transport essential liquids to the front, allowing for the delivery of water, food, medicines or cleaning agents to those trapped in difficult to reach areas following a disaster, for example.

In addition to serving as a search and rescue device, RoBoa can also be used as an industrial inspection tool for pipes, sewers or tanks in the wastewater, power and chemical manufacturing industries.
