The untethered biohybrid microswimmer is able to transport and deliver cargo encapsulated into a guidable red blood cell, while an attached bacterium, one of the most efficient swimmers in nature, acts as a propeller to move it forward. Once it has reached its destination and delivered its cargo, the scientists can destroy the microswimmer using infrared light.
The postdoctoral researcher from the Physical Intelligence Department at the Max-Planck-Institute for Intelligent Systems in Stuttgart is one of the 600 young scientists who is given the opportunity for a week of scientific exchange with the greatest minds in medical research.
Each year, the Alexander von Humboldt Foundation grants approximately 500 fellowships to Postdoctoral Researchers of all nationalities and disciplines from abroad to continue their research in Germany. Four AvH fellows join the Max Planck Institute for Intelligent Systems in Stuttgart.
A magnetic drive allows a tiny untethered vehicle to walk, crawl, jump and swim through a complex environment
Tiny robots need not fear obstacle courses in the future: Scientists from the Max Planck Institute for Intelligent Systems in Stuttgart have developed a minuscule, flexible robot that can master a variety of forms of movement. Its magnetic drive allows it to walk, crawl and roll through difficult terrain. Moreover, it can transport small loads and swim on and in liquids. In future, tiny robots moving in this way could transport medication specifically to where it is needed.
Scientists at the Max Planck Institute for Intelligent Systems invented a magnetically controlled soft robot only four millimeters in size, that can walk, crawl or roll through uneven terrain, carry cargo, climb onto the water surface, and even swim in it. The inspiration comes from soft-bodied beetle larvae and caterpillars, and even jellyfishes posed as biological models. One day, this small-scale robot may enable targeted drug delivery or minimally invasive surgery, the researchers hope. Its multiple locomotion capability in complex environments is so unique that science journal Nature will publish the researchers´ findings in its February edition.
New book from Metin Sitti
Progress in micro- and nano-scale science and technology has created a demand for new microsystems for high-impact applications in healthcare, biotechnology, manufacturing, and mobile sensor networks. The new robotics field of microrobotics has emerged to extend our interactions and explorations to sub-millimeter scales. This is the first textbook on micron-scale mobile robotics, introducing the fundamentals of design, analysis, fabrication, and control, and drawing on case studies of existing approaches.

Swallowable biopsy robot of doom
Scientists under the lead of Metin Sitti at the Max Planck Institute for Intelligent Systems in Stuttgart have recently constructed a material system that provides dynamic self-assembly.
To be alive, biologically speaking, means to be able to breath, to eat, to drink, to grow, to age, and, perhaps, to move. Food is the energy source, and metabolism translates the stored chemical energy into biochemical energy to sustain live functions. The physical abstraction of this energy transduction by living organisms is extremely simple: it involves energy input and energy dissipation. This mechanistic view of life looks almost trivial, but to apply this type of thinking in the design of materials and material systems is non-trivial. Scientists under the lead of Metin Sitti at the Max Planck Institute for Intelligent Systems in Stuttgart have recently constructed a material system that requires continuous magnetic energy input and viscous dissipation to maintain its spatiotemporal patterns, and the term usually used to describe this type of material system in the research community is dynamic self-assembly.
Penn alumnus Zoey Davidson, now a postdoc at the Max Planck Institute for Intelligent Systems in Germany, had been experimenting with Sunset Yellow, a dye that gives Doritos and orange soft drinks their bright colors, when he accidentally spilled some of the material.
