Not exact matches
«We have shown that we can manually direct the robots or give it a set of coordinates to get it from point A to point B, but our goal in this research is to enable the microrobots to navigate a course with random impediments blocking its way,» Kim said.

When a slimy smear of the bacteria is applied to a substrate, in this case a square chip of photosensitive material called SU - 8, you get a negatively charged microrobot that can move around in a fluid by riding the waves of an electric field.
«With this level of control and input from the environment we can program the microrobot to make a series of value judgments during its journey that affect its path,» Kim said.
In a follow - up to a 2014 report that presented a way to use the flagellated bacteria Serratia marcescens and an electric field to make a microrobot mobile, MinJun Kim, PhD, a professor in the College of Engineering and director of Drexel's Biological Actuation, Sensing & Transport (BAST) Lab, is now offering a method for making them agile.
To make smaller, simpler microrobots, researchers at Drexel University have developed a fabrication method which utilizes the minimum geometric requirements for fluid motion — consisting of just two conjoined microparticles coated with bits of magnetic debris.
When a microrobot is exposed to an external magnetic field — the offboard power source, given the difficulty in shrinking batteries to the size of bacteria — it begins to spin and move in a manner similar to bacterial flagella, courtesy of the iron oxide debris.
We hope that our work investigating tradeoffs like weight and surface tension can inspire future multi-functional microrobots — ones that can move on complex terrains and perform a variety of tasks.»
«This is the first microrobot capable of repeatedly moving in and through complex environments,» said Yufeng Chen, who was a graduate student in the Microrobotics Lab at SEAS when the research was conducted and is first author of the paper.
«There are more challenges to making a robust, robotic landing system but this experimental result demonstrates a very versatile solution to the problem of keeping flying microrobots operating longer without quickly draining power,» said Ma.
