Researcher Daan Hobbelen of TU Delft has developed a new, highly-advanced walking robot: Flame. This type of research, for which Hobbelen will receive his PhD on Friday 30 May, is important as it provides insight into how people walk. This can in turn help people with walking difficulties through improved diagnoses, training and rehabilitation equipment. TU Delft is a pioneer of the other method used for constructing walking robots, based on the way humans walk. This is really very similar to falling forward in a controlled fashion. Adopting this method replaces the cautious, rigid way in which robots walk with the more fluid, energy-efficient movement used by humans. PhD student Daan Hobbelen has demonstrated for the first time that a robot can be both energy-efficient and highly stable. His breakthrough came in inventing a suitable method for measuring the stability of the way people walk for the first time. This is remarkable, as 'falling forward' is traditionally viewed as an unstable movement. Modelling the walking process allows researchers to construct two-legged robots which walk more naturally. More insight into the walking process can in turn help people with walking difficulties, for example through improved diagnoses, training and rehabilitation equipment. TU Delft is working on this together with motion scientists at VU University Amsterdam. Hobbelen cites ankles as an example. These joints are a type of spring which can be used to define the best level of elasticity. Research conducted by Hobbelen into Flame's ankles has provided motion scientists with more insight into this topic.
