A big thanks to authors Akash Vardhan, Ram Avinery, Hosain Bagheri, Velin Kojohourav, Shengkai Li, Hridesh Kedia, Tianyu Wang, Daniel Soto, Kurt Wiesenfeld, and Dan Goldman for their great work!
Actively-driven #robots can produce a rich variety of emergent phenomena, including behaviors that appear counterintuitive at first. In a recent preprint from the Goldman Lab at @GeorgiaTech, undulating robots form long-lived pairs mediated solely by repulsive interactions.
These principles—emergent behavior arising from actively-driven, deformable objects—are relevant to many living systems. From single-celled organisms to swarms of insects, "smart" behavior can arise from groups of "dumb" individuals, modulated by simple mechanical interactions.

Please join us this Thursday for the final PoLS Lunch & Learn of the semester! This week's speaker will be Chris Zhang from the Hammer and @wc_ratcliff labs.
Imaging in C. elegans shows that environmental resistance modulates how neural signals are translated into movement by altering the timing between muscle activation and body bending.

Animals at many length scales move through undulation. In a new paper, Chris Pierce and the Goldman Lab use the nematode 🪱 C. elegans to show how interactions with the environment cause undulating body movements to become desynchronized to the phase of muscle contractions.
They built a mechanical model showing that phase lags result from a combination of internal elastic torques and external resistive forces. The worm's gait pattern is not purely neural—it's shaped by physics!
