In a recent episode of the Soft Robotics Podcast, host Marwa ElDiwiny and engineer Scott Walter explored the ongoing debate between rotary and linear actuators in the development of humanoid robots. The discussion highlighted the reasons behind the preference for compact rotary joints among most builders, while also examining the advantages of planetary-roller-screw cylinders favored by some engineers. This analysis reflects the evolving landscape of robotics, where design choices are critical to enhancing functionality and efficiency in humanoid systems. The podcast aims to inform listeners about the technical considerations and implications of these actuator types in the field of robotics.
