Kirstin Petersen, an Associate Professor at Cornell University and leader of the Collective Embodied Intelligence Lab, discusses her research into robot swarms inspired by social insects like ants, bees, and slime molds. She explains the distinction between centralized teams and distributed swarms, highlighting how nature achieves resilience through local interaction and environmental modification rather than global planning. The conversation covers specific applications such as autonomous robotic construction for housing and hostile environments, the potential of soft robot swarms, and the use of simple, low-cost robots to achieve complex emergent behaviors.
Other shows on the same ground, closest first.
Hosts Daniel and Forbode discuss a Harvard University research project that mimics ant colony behavior to create a decentralized swarm robotics system called 'RANTS'. They explain how the robots use 'photo-pheromones' (light gradients) to coordinate excavation tasks without central control, offering a lightweight alternative to complex AI. The episode also touches on the hosts' sponsor segment regarding IoT solutions for traffic congestion.
Hosts Daniel and Forbode discuss the M4, a bio-inspired multimodal robot developed by Caltech and NASA JPL that can fly, roll, walk, and tumble using eight different modes of locomotion. They highlight how the robot's AI autonomously selects the best traversal method based on terrain, drawing inspiration from nature such as birds and sea lions. The episode also covers Jonathan Schultz of Team Huge, whose BattleBots design philosophy of accessible core components parallels the M4's adaptive engineering, while exploring applications in space exploration, emergency rescue, and last-mile delivery.
Hosts Daniel and Forbode discuss biomimicry breakthroughs from the University of Washington and Harvard, focusing on dandelion-inspired sensors and microscale robotic cilia. The University of Washington team created 24-milligram solar-powered sensors using Microchip's A20 Tiny processor and Kapton parachutes to deploy environmental monitoring networks via drones. Meanwhile, Harvard researchers developed self-propelled cilia from photo-responsive liquid crystal elastomers, enabling complex, programmable motion for applications in drug delivery and physical encryption.
Mario Mauerer, Global Robotics Business Manager at Maxon, discusses how humanoid robots are driving actuator innovation, focusing on torque density, simulation models, and safety architectures for commercialization by 2027-2028. David Koelle, Principal Software Engineer at Charles River Analytics, details the NASA ASTRA project, explaining their 'theory of mind' approach to swarm robotics for lunar exploration, which allows heterogeneous robots to coordinate tasks without constant communication. The episode also covers recent industry funding rounds for companies like Waymo and Limox Dynamics, and new US legislation aimed at securing the humanoid supply chain.
Daniel and Forbode discuss research from the Technical University of Munich on using swarms of drones to 3D print concrete structures, inspired by the collective behavior of bees. They analyze the system's use of scanning and printing drones, a novel cementitious resin material, and self-correcting nozzles to achieve millimeter precision. The hosts critique the technology's scalability, highlighting significant challenges with wind stability, battery life, and material weight, while suggesting tethered power or hybrid ground-air robots as potential solutions for maintenance tasks like wind turbine repair.
