## Summary

Rich Walker, Director of Shadow Robot Company, discusses the evolution of dexterous robotic hands, contrasting their anthropomorphic Shadow Hand with a robust, non-anthropomorphic hand developed for Google DeepMind. He explains the engineering trade-offs between lightweight soft actuation and heavy motors, and the challenges of defining 'dexterity' in research and industrial applications. Walker also addresses the policy hurdles for robotics SMEs, arguing that robots are substrate tools rather than end-products, and critiques the current hype surrounding humanoid robots as a financing strategy rather than a technical necessity.
