We have been developing an endoskeletal robot suit (StillSuit) to support the aging society. Our StillSuit is designed for cognitive and physical interventions on the human mind and body by taking advantage of endogenous flexibility, namely, remodeling. 

Project Description and Objectives

Our approach is based on the implementation of biologically relevant neuro-musculoskeletal models in the HBP Neurorobotics Platform (NRP) framework, by which we achieve the embodiment of the computational brain model in the physical world. The musculoskeletal models considered for inclusion comprise non-human animals and human-based models with feasible yet sufficient granularity. These models are obtained by using an in-house X-ray CT scanning device and advanced image processing, which allow us to extract functional-anatomical information from experimental animals. Motion data are obtained by motion capture systems, collaborating with animal experimentation facilities.

These biologically relevant musculoskeletal models make it possible to analyze neurological and motor phenotypes relevant to human health and diseases in animal models: i.e., we conduct computational and physical experiments with the body models/neurorobots integrated with the computational brain model. Through this process we aim to elucidate fundamental mechanisms of neuro-motor functions of human and non-human animals.

With the same tools, another goal will be the study of retargeting (functional mapping) of the musculo-skeletal systems and associated motor control schemes between evolutionarily related species (e.g., rodents and humans), in both biological models and physical/virtual neurorobots. To that end we will implement algorithms that have been developed in RIKEN: these automatically transform a controller created for a given body into a controller adapted to a second body with different kinematics. We will then use the NRP to study the functional relevance of the obtained controller in simulation, and therefore gain insight about the performance of the retargeting algorithm. This approach may enable us to establish principles of motor control that are invariant across species, and in parallel to probe the usefulness of these tools for robot design.
