| - | ==== LIving with Robots and InteractivE Companions ==== | + | toulouse lasergame evolution.com http:// |
| - | + | ||
| - | LIREC aims to establish a multi-faceted theory of artificial long-term companions (including memory, emotions, cognition, communication, | + | |
| - | + | ||
| - | ==Links== | + | |
| - | + | ||
| - | http://www.lirec.org | + | |
| - | + | ||
| - | ==Agent platforms== | + | |
| - | + | ||
| - | The platforms currently under consideration for long term companions are: | + | |
| - | * Mobile robots | + | |
| - | * Fixed robots | + | |
| - | * Handheld devices | + | |
| - | * Fixed graphical systems | + | |
| - | + | ||
| - | ==Migration== | + | |
| - | + | ||
| - | An interesting feature of the research is migration betwen these platforms. Agents which need to build up a long term relationship with their users will have to switch forms depending on the needs of the user at different times. The migration of an agent between devices, and how people relate to it, is a core element of the research. | + | |
| - | + | ||
| - | ===Scenarios=== | + | |
| - | + | ||
| - | In order to test and showcase the technology developed for lirec, several scenarios have been designed to promote companionship. These scenarios are shared between three of the research partners. | + | |
| - | + | ||
| - | ==Heriot Watt== | + | |
| - | Spirit of the building: | + | |
| - | - Team buddy, mobile robot, collective memory for a lab team | + | |
| - | - Personal guide - for navigating around a university campus, remember appointments etc | + | |
| - | - In the wild - a gossip/chat robot - appears on a large screen in social area | + | |
| - | + | ||
| - | ==INESC-ID== | + | |
| - | - Game companion for young children | + | |
| - | - Personal trainer (migrate to mobile robot for jogging exercises etc) | + | |
| - | - Welcome to the jungle - talk to game characters through a robot, robot can alternate | + | |
| - | between real and game world | + | |
| - | + | ||
| - | ==The University of Hertfordshire== | + | |
| - | - Fetch and carry, help with physical impairment or convenience | + | |
| - | - Cognitive prosthetic - memory aid for tasks etc | + | |
| - | - Telepresence card player - robot mediates play | + | |
| - | - Teaching Proxemic preferences - robot learns where to be relative to the user in different situations | + | |
| - | - Travelling companion - agent migration, to stay with user during home, work, shopping. | + | |
| - | + | ||
| - | ===Experimental testing=== | + | |
| - | + | ||
| - | All scenarios are to be experimentally tested in public. | + | |
| - | + | ||
| - | ===Architecture=== | + | |
| - | + | ||
| - | The technology developed for lirec is shared between the research partners, and has to: | + | |
| - | | + | |
| - | | + | |
| - | - Support migration at runtime between platforms | + | |
| - | + | ||
| - | ==Existing robot architectures== | + | |
| - | In the whole, there has historically been a lack of sharing of this kind of technology. This is partly because generalising is hard, considering all types of robots possible. However, Lirec has to generalise as it's using a wide variety of architectures and needs to share as much as possible. | + | |
| - | + | ||
| - | While some existing architectures are available, none of them address the needs of lirec, given the focus: | + | |
| - | | + | |
| - | - Working across different platforms | + | |
| - | + | ||
| - | ==Methodology== | + | |
| - | In the past there have been 2 broad approaches to robot design: | + | |
| - | * Hierarchical, | + | |
| - | * Behavioural approach = less state, local decisions, liable to local minima, opaque to program | + | |
| - | This can be summed up as predictive vs reactive. | + | |
| - | + | ||
| - | The plan is to use a hybrid approach, example [[http://www.techfak.net/ags/ai/projects/BIRON/ | + | |
| - | + | ||
| - | The architecture will consist of 3 layers of abstraction: | + | |
| - | * Level 1 - device layer, platform dependant | + | |
| - | * Level 2 - platform dependant | + | |
| - | * Level 3 - ION, platform independent | + | |
| - | + | ||
| - | Level 2 will provide a reference architecture with modular capabilities called competencies. Not all competencies will make sense for all platforms, and different implementations of the same competency will be needed for different platforms. | + | |
| - | + | ||
| - | Example competencies: | + | |
| - | * Face finding | + | |
| - | * Expression recognition | + | |
| - | * Text to speech | + | |
| - | * Obstacle avoidance | + | |
| - | + | ||
| - | [[http://eris.liralab.it/yarp/|YARP]] is a good example of sharing code in this way on a Linux platform. | + | |
