Researchers have developed a new way of designing, manufacturing and actuating tiny bots, which improved their speed and maneuverability, and also made it possible to change the configuration to perform additional tasks.
Most of the microbot existing today have limited mobility, which significantly reduces the potential of their application. To increase the range of motion, they should be able to bend at large corners. To achieve this, scientists from the University of Michigan decided to use the principles underlying the art of origami.
The team has created various robots in size no more than a centimeter, which can be 90 ° and more, which allows them to transform into more complex forms. It also gave them the opportunity to perform movements in the operating range up to 80 times per second.
Unlike other mechanisms using origami principles created by microobots, they do not require the activation of external influence, such as a heat or magnetic field. Instead, the team used a layer of gold and polymer, which under the action of an electric current perform the role of onboard drive.
When current passes through a layer of gold, it creates heat, by means of which the movements of a miniature robot can be controlled. To change its form, it is enough to overload the system, program the desired folds and give them to cool. It provides elasticity and allows you to restore the initial configuration.
