Drone that can catch another by firing a net at it
Engineers from Human-Interactive Robotics Lab (HIRoLab) at Michigan Technological University have filed a patent for a prototype for a drone-catching system that fires a net to take other unwanted aircraft down.
They have named the project Robotic Falconry and have said that the drone, equipped with a net shooter, can intercept and physically remove any intruding multi-rotor drone from private airspace. It can be autonomous or remote-controlled while tackling a drone.
According to the researchers, the net-shooting technique can be effective when force-landing unmanned intruders that would otherwise put the public at risk.
Drone that can do donuts, figure-eights around obstacles
Getting drones to fly around without hitting things is a huge task. Obstacle-detection and motion-planning are two of computer science’s trickiest challenges, because of the complexity involved in creating real-time flight plans that avoid obstacles and handle surprises like wind and weather.
Two teams of researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have developed software that allows drones to stop on a dime to make hairpin movements over, under and around some 26 distinct obstacles in a simulated forest.
One team has shown a small quad-rotor doing donuts and figure-eights through an obstacle course of strings and PVC pipes.
In a second CSAIL project, PhD student Anirudha Majumdar showed off a fixed-wing plane that avoids obstacles without any advance knowledge of the space, and even in the face of wind gusts and other dynamics. The approach was to pre-program a library of dozens of distinct funnels that represent the worst-case behaviour of the system, calculated via a rigorous verification algorithm.
Polymer super suit designed using solar energy
The Grossman group of MIT has developed a transparent polymer that can store energy by using a solar cell and release controllable heat at any time. This newly-engineered material depends upon the Sun, which is a practically inexhaustible source of energy and stores energy in the form of chemical energy, releasing it later as heat.
Jeffrey Grossman, lead researcher, has said that the product could be a boon for the clothing industry, and provide humans with a new type of protective wear. The team also explained that this concept first came to their mind while analysing the concept of harvesting solar energy for long-term usage, as required in various sectors.
Conventionally, solar energy is converted to electrical energy and serves as an environment-friendly renewable energy source, but the researchers wanted to come up with something new and innovative by using similar ideas.
