Millirobot with a talent for versatility of movement

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._ Max Planck Gesellschaft.
