Small-scale untethered mobile robots have the unique capability of accessing to small spaces and scales directly. Due to their small size and small-scale physics and dynamics, they could be agile and portable, and could be inexpensive and in large numbers if they are mass-produced. They would have high impact applications in health-care, bioengineering, environment monitoring, and inspection. In this talk, design, fabrication, and control of different size-scale miniature mobile robots leveraging advanced and soft materials are presented. First, as millimeter scale mobile robots, novel climbing, flying, jumping-gliding, and water-running robots inspired by insects, bats, and lizards are presented. Novel gecko-inspired micro-fiber adhesives using intermolecular forces such as van der Walls forces are shown to enable many new miniature robot and robotic manipulation applications. Pill-size untethered soft capsule robots are proposed to enable minimally invasive medical diagnosis and therapeutic operations inside stomach. Next, going down to micrometer length-scale mobile robots, the grand challenge is the limitation on scaling down on-board actuators and power sources. Two alternative approaches are proposed to solve this challenge. First, biological cells, e.g. bacteria, attached to the surface of a microrobot are used as on-board microactuators and microsensors using the chemical energy. Bacteria-driven microswimmers are steered using chemical and pH gradients in the environment and remote magnetic fields for targeted drug delivery applications. As the second approach, external actuation of synthetic magnetic microrobots using remote magnetic fields in enclosed spaces is demonstrated. Novel composite materials are used to enable soft magnetic microrobots with diverse locomotion and functional capabilities. Such untethered microrobots are used in bioengineering and medical applications and can self-assemble into different patterns dynamically and statically.
