Academic year 2017/18 (first semester)
Aims: This module presents locomotion and haptic interfaces for VR exploration, giving special emphasis to control issues. It introduces in particular two haptic devices (Geomagic Touch and Cyberith Virtualizer/Oculus Rift) available in the DIAG Robotics Laboratory, with some applications. It summarizes also the research results obtained by our Robotics group (see here) within the European project Cyberwalk.
Detailed contents: General introduction to haptic and locomotion interfaces with several illustrative examples. Two specific hardware devices: the Geomatic Touch haptic interface; the Cyberith Virtualizer locomotion interface (with the Oculus Rift HMD). Possible applications of these interfaces. Design, construction, actuation, sensing, modelling, and system issues for two locomotion platforms for VR exploration, developed within the CyberWalk project: the CyberCarpet (ball-array) and the CyberWalk platform (2D, omni-directional). Control design and experimental validation for the CyberCarpet. Control design and experimental validation for a 1D treadmill. Control design, experimental validation, and perceptual evaluation for the 2D CyberWalk platform.
Prerequisites: This module has no strict prerequisites. However, it is suggested to have acquaintance with the basic topics of Robotics 1 and Robotics 2, or with those treated in Autonomous and Mobile Robotics.
ECTS credits for this module: 3 credits (out of 12 credits for the entire course).

After attending classes, students should either give a presentation with slides on a certain topic (based on technical papers) or develop a small project (in general, involving simulations). Work can be done alone or in groups, typically by two students for presentations and three students for small projects. Presentations and projects should be completed by the end of June 2018.
Note that in order to obtain the 12 credits of Elective in Robotics, it is necessary to complete all four modules (each of 3 credits). Altogether, each student should give two (2) presentations and complete two (2) small projects. For more details, see the main page of Elective in Robotics.
