Specialists at Purdue University are wanting to send groups of little robots in fields running from assembling to medication. To control them, researchers have added to an innovation compared to “mini force fields.”

Analysts need the robots to work together and collectively, and be controlled independently. To do as such, they manufactured little remote controls made of planar curls. The curls can transmit individualized magnetic fields.

The planar curls on the edges of the “workspace” were earlier employed where the robots have been deployed. But this meant only a general power field. David Cappelleri, an assistant professor of mechanical engineering at Purdue University, and his partners came up with another way to create better and closer control.

“The approach we came up with works at the microscale, and it will be the first one that can give truly independent motion of multiple microrobots in the same workspace because we are able to produce localized fields as opposed to a global field,” Cappelleri said. “What we can do now, instead of having these coils all around on the outside, is to print planar coils directly onto the substrate.”

Researchers can vary the forces exerted on individual robots my manipulating the strength of the electric current running through the tiny coils.

The researchers are working to create microrobots of the size of 250 microns, as small as a dust mite!

These microbots will have a lot of uses.  For example, we have the ability to perform additive manufacturing — assembling delicate electronic components.  Use in cancer is the most interesting.

“Cancer cells have different stiffness characteristics than non-cancer cells, and in some of our previous work we put force sensors on the end of these robots to figure out which ones are stiffer than others,” Cappelleri said.

Let us look where and how these microbots which act individually but are controlled collectively.
