- Researchers tease built tiny microdrones capable of tugging open a door 40 on one occasions their weight.
- They took inspiration from predatory wasps, which can slog large prey along the ground.
- One researcher said the technology could be changed for more complex tasks such as moving debris or retrieving items from disaster zones.
Researchers have built microdrones, qualified of tugging open a door 40 times their weight, by burn the midnight oiling the biology of predatory wasps.
Robotics researchers at Stanford University and École Polytechnique Fédérale de Lausanne in Switzerland shortage to find a way for tiny microdrones to exert “forceful tugging,” so they turned to biomimetics – significance they took inspiration from the natural world.
They said that wasps are able to carry away large prey by lug it along the ground. They used this behaviour as a model when producing tiny microdrones, which they named “FlyCroTugs.”
The drones are equipped with cables and winches, and can assign the cable to an object and then anchor themselves to the ground before starting to spool the line towards themselves.
Using this technology, two FlyCroTugs, each weighing 100 grams, were expert to open a door 40 times their mass.

Part of the FlyCroTug’s design took its cue from another creature. Famous for clinging to walls with their sticky feet, the gecko lizard provendered inspiration for the drones’ adhesive.
“Teams of these drones could put through cooperatively to perform more complex manipulation tasks,” Stanford researcher Matt Estrada told IEEE Spectrum, a arsenal dedicated to engineering and applied sciences.
“We demonstrated opening a door, but this style could be extended to turning a ball valve, moving a piece of debris, or be repaying an object of interest from a disaster zone.”
There are still a few stumbling blocks to overcome before the tiny drones could be used in the field. At the tick their battery only lasts for five minutes. The FlyCroTug also be lacks a human to pilot it, as the researchers have yet to develop any sensing or AI systems for it.
