Researchers at College of Colorado Boulder’s ATLAS Institute and College of Calgary have not too long ago developed an actuated, expandable construction that can be utilized to manufacture shape-changing aerial robots. In a paper pre-published on arXiv, they launched a brand new robot, dubbed PufferBot, which was constructed utilizing this distinctive and revolutionary construction.
“One of many main targets of our analysis is to deal with a longstanding downside in robotics, which is that robots stay extraordinarily troublesome for individuals to work with,” Hooman Hedayati, one of many researchers who carried out the examine, advised TechXplore. “There are a number of causes for this, together with human inexperience with robots, issues of safety that robots introduce, and an absence of consideration concerning how people and robots can successfully talk. All of those points are compounded after we think about aerial robots (i.e., drones).”
Of their current examine, Hedayati and his colleagues got down to examine completely different methods that might enable roboticists to “re-design” and alter the normal construction of drones. Drawing inspiration from the increasing capabilities and organic traits of pufferfish, they created a brand new construction that enables drones to quickly change form by increasing and contracting.
The construction they designed, primarily based on an expandable body and an actuator with one diploma of freedom, additionally replicates the enlargement of airbags in autos. It thus has a number of benefits over extra typical drone designs, as it could possibly restrict the harm brought on by a robot’s collision with objects in its environment, similar to airbags present higher security for human drivers.
“Our design gives a number of new communicative properties and potential security advantages, as within the case of a collision or crash, the expandable construction can cut back impacts to each the robot and regardless of the robot hits,” Hedayati defined. “PufferBot has a one-degree-of-freedom actuator that controls the scale and stiffness of an expandable construction that surrounds a drone. For instance, when the drone is flying by way of a cluttered area or whether it is about to collide with an object, the actuator can deploy the construction to guard the drone by masking its propellers and inner electronics.”
In distinction with current methods that use static propeller guards, the construction devised by the researchers is adjustable and will be of various sizes. Because of this it doesn’t essentially lower a drone’s maneuverability.
Because it supplies robots with the power to considerably change their measurement and look (by shrinking and increasing), the construction might additionally function a helpful communication device. For instance, a drone may very well be programmed to broaden when it senses a selected kind of risk or stimulus in its setting, in an effort to warn people from a distance.

“From our perspective, robots that may change their form and measurement are comparatively underexplored within the discipline of robotics, whereas some fascinating and associated developments are ongoing within the space of tensegrity robots and reconfigurable rovers,” Hedayati mentioned. “Basically, we imagine the expandable construction we developed may help in some ways for robot operators, collocated people, and the robot itself. As an illustration, it might assist drone operators fly drones with extra confidence, understanding that they’ve a deployable body that may be activated to scale back the danger of collision.”
PufferBot might show notably helpful for finishing missions in environments the place robots have the next likelihood of colliding with different objects. As well as, the expandable construction it’s primarily based on may very well be tailored and used to construct different drones or robots with the identical increasing and shrinking capabilities.

“Going ahead, we’re desirous about exploring how actuated, expandable constructions, resembling these utilized in PufferBot, can assist human-robot interactions by enabling robots to be extra expressive,” Hedayati mentioned. “Particularly, we need to examine how such constructions would possibly allow a robot to make use of new varieties of ‘gestures’ to convey info resembling, ‘don’t come shut’ or ‘it is best to go on this route,’ and many others. to people.”
