This interaction becomes even more critical when the robot must move on rough surfaces. This paper presents a new visual contact analysis, based on curved patches that model local contact surfaces both on the sole of the robot's foot and in the terrain. The focus is on rigid, flat feet that represent the majority of the designs for current humanoids, but we also show how the introduced framework could be extended to other foot profiles, such as spherical feet. The footholds are localized visually in the environment's point cloud through a fast patch fitting process and a contact analysis between patches on the sole of the foot and in the surrounding environment. These patches aim to compose a spatial patch map for contact reasoning. We experimentally validate the introduced visionbased framework, using range data for rough terrain stepping demonstrations on the COMAN and WALK-MAN humanoids.","PeriodicalId":143992,"journal":{"name":"2017 IEEE-RAS 17th International Conference on Humanoid Robotics (Humanoids)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129002936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal of our study was to compare twelve ablebodied and amputee sprinting motions which were synthesized by combinations of ten optimality criteria. We created rigid multi-body system models with 13 degrees of freedom in the sagittal plane for both an able-bodied and an amputee sprinter. The joints are powered by torque actuators, except for the prosthetic joint which is equipped with a passive linear springdamper system. The sprinting motions are the solutions of an optimal control problem with periodicity constraints and objective functions which combine different optimality criteria. For both athletes, we found realistic human-like sprinting motions. The analysis of the motions suggested that the amputee athlete applies less active joint torque in the hip and knee of his affected leg compared to the able-bodied athlete.","PeriodicalId":143992,"journal":{"name":"2017 IEEE-RAS 17th International Conference on Humanoid Robotics (Humanoids)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121799177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Humanoid robots are acquiring the ability for locomotion in horizontal directions so far, and the ability for vertical locomotion is now required in order to extend their range of activities further. Therefore, we propose rappelling as a method for vertical locomotion. Rappelling is a method to descend from a high place using a rope and a belay device. With this method, humanoid robots are expected to get the ability for vertical locomotion without additional actuators. In this paper, we propose a full-body motion for rappelling based on the sequential transition of the centroid position and the contact states. We also propose the reliable manipulation of a rope grasped by both hands. With the proposed methods, we conducted an experiment of rappelling with HRP2, and it could successfully descend from a height of 2m50cm in 277 seconds.","PeriodicalId":143992,"journal":{"name":"2017 IEEE-RAS 17th International Conference on Humanoid Robotics (Humanoids)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132584477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To quantify a system's inherent balance capabilities, we define momentum gains for general 2D and 3D models. We provide two methods for calculating these gains, and relate both velocity and momentum gains to the centroidal momentum of a system, a commonly used measure of aggregate system behavior. Finally, we compare velocity and momentum gains as criteria for the design of simple balancing systems using a parameterized optimization framework.","PeriodicalId":143992,"journal":{"name":"2017 IEEE-RAS 17th International Conference on Humanoid Robotics (Humanoids)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132761346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Robot Operating System (ROS) has, for many, become the de facto software framework for communication standardisation and hardware interface abstraction, and various packages within its ecosystem have come to the fore as being reliable design choices for dictating control flow. ROSbased software packages that use state machines as their core methodology to bridge the gap between low-level imperative task scripting and higher-level task planning have proven particularly popular. However, while they provide much in terms of power and flexibility, their overall task-level simplicity can often be obfuscated at the script-level by boilerplate code, intricate structure and lack of code reuse between state machine prototypes. In this paper, we aim to address this deficit by proposing a code generation, templating and metascripting methodology for state machine assembly, as well as an accompanying application programming interface (API), for the rapid, modular development of robot control programs. The API has been developed to function effectively as either a frontend for concise scripting or a back-end for code generation for visual programming systems. Its capabilities are demonstrated in an experiment using a simulated humanoid robot platform.","PeriodicalId":143992,"journal":{"name":"2017 IEEE-RAS 17th International Conference on Humanoid Robotics (Humanoids)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117084194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The approach is based on a projection of the control input onto the nullspace of the linearized constraints. We derive a fully constraint-compliant feedforward-feedback control update rule, for which we can solve efficiently with Riccati-style difference equations. We assume that the relative degree of all constraints in the discrete-time system model is equal to one, which often holds for robotics problems employing rigid-body dynamic models.
