A PatentVest analysis reveals a significant disconnect between venture capital funding and intellectual property defensibility among humanoid robotics startups, raising questions about long-term viability in a rapidly evolving market.
Soft Robotics Podcast host Marwa ElDiwiny and engineer Scott Walter dissect the rotary-vs-linear actuator debate shaping today’s humanoid robots—explaining why most builders favor compact rotary joints while others bet on planetary-roller-screw cylinders.
Corporate venture capital investment in robotics startups surged 183% YoY in Q1 2024, reaching $1.3 billion across 34 deals. Driven by AI advancements and manufacturing needs like onshoring, corporations are investing both to supply components for and deploy next‑generation robots, most notably humanoids.
Figure CEO Brett Adcock refuted a Fast Company claim that his company uses planetary roller screws, stating Figure relies on rotary actuators. The dispute highlights a key design debate in humanoid robotics: direct rotary drive versus linear actuators (which use screws) with linkages, as detailed by expert Scott Walter.
