(5/6) Key to this RT motion is our robot's rolling-without-slipping, inertia-less active motion, which is expected in microswimmers. To confirm this, we used a slippery surface coated with coconut oil and found that the sudden tumble events smoothened out and vanished completely.

(4/6) When robots are programmed to execute overdamped active Brownian (AB) motion, voila, RT motion emerges, featuring abrupt tumbling events and exponential run-time distributions.

(3/6) Inspired by that, we create a robotic organism: two self-propelled robots connected by a rigid rod. Here, robots mimic flagella, and the rod acts as the organism's body. The rod rotates freely in a plane, with its ends pivoted at mirror-symmetric points on each robot.

(1/6) 📢Excited to share our latest work in collaboration with @harshIITMandi's group at IIT Mandi on an artificial robotic system 🤖, in experiment and theory, mimicking run-and-tumble (RT) motion seen in microorganisms 🦠. 🧵⏬
