Image sequence showing a microrobot navigating within a microfluidic channel under flow conditions. Initially, when the microrobot was at the centre of the channel (0.0 to 6.7 s), it encountered maximum drag before moving towards the wall (7.8 to 31.4 s), where the drag was minimal. The reduced drag forces at the wall facilitated more stable and controlled navigation. The red arrows indicate the direction of the fluid flow. Scale bar, 200 m.
