The Peristaltic Transit Pod is a subsurface personal transport vehicle designed by Zheng-Dao Bioelectric for navigation through the dense utility tunnel networks, fluid conduit systems, and bio-infrastructure channels that run beneath GLMZ's built environment. Unlike conventional tunnel vehicles that rely on wheels or tracks, the Pod moves through a biomimetic peristaltic propulsion system — a series of circumferential contraction rings along its exterior that produce a rhythmic, wave-like motion, allowing the vehicle to travel through curved, irregular, and partially obstructed passages that would defeat rigid-chassis alternatives. The outer hull is coated in a Zheng-Dao proprietary biofilm that reduces friction against tunnel walls and actively resists the corrosive biological and chemical compounds common in subsurface environments.
