Non-Buoyant Microrobots Swimming with Near-Zero Angle of Attack

IROS 2025

In the design of microrobots, a helical geometry is pivotal to overcome the time-reversal constraints of the scallop theorem. The helical geometry enables the microrobots to propel themselves forward in viscous fluids with a corkscrew like motion when they are allowed to rotate. It is physically adv

Helical Propulsion in Low-Re Numbers with Near-Zero Angle of Attack

IROS 2023poster

One approach to the wireless actuation and gravity compensation of untethered helical magnetic devices (UHMD) is through swimming with a non-zero angle of attack (AoA). This configuration allows us to counteract gravity, so that for a given desired path, we can move the UHMD controllably without dri…
