- | ==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 between 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, a mobile robot/collective memory for a team working in a lab | + | |
- | - Personal guide - for navigating around a university campus, remembering appointments, | + | |
- | - In the wild - a gossip/chat robot - appears on a large screen in a social area | + | |
- | + | ||
- | ==INESC-ID== | + | |
- | - Game companion for young children | + | |
- | - Personal trainer - which can migrate to mobile robot for jogging exercises | + | |
- | - Welcome to the jungle - talk to game characters through a robot which can alternate between real and game world | + | |
- | + | ||
- | ==The University of Hertfordshire== | + | |
- | - Fetch and carry, to help with physical impairment or provide convenience | + | |
- | - Cognitive prosthetic - memory aid for tasks | + | |
- | - Telepresence card player - a robot mediates play between two people | + | |
- | - Teaching proxemic preferences - a 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 developed are to be experimentally tested and showcased to the 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 and implementations possible. However, Lirec has to generalise as it's using a wide variety of platforms 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 is: | + | |
- | - Long term companionship rather than solving a purely technical problem | + | |
- | - Working across different platforms | + | |
- | + | ||
- | ==Methodology== | + | |
- | In the past there have been 2 broad approaches to [[robot design]]: | + | |
- | * Hierarchical, | + | |
- | * Behavioural approach = less state, local decisions, but liable to local minima and opaque to program | + | |
- | This can be summed up as " | + | |
- | + | ||
- | 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 - The device layer, hardware drivers | + | |
- | * 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. | + | |
- | + | ||
- | Competencies table | + | |
- | ^ Actuation ^^^^ Sensing ^^^^^^ | + | |
- | | **Speech/Sound** | **Visual** | **Movement** | **Object Manipulation** | **Identification** | **Vision** | **Sounds** | **Positioning** | **Distance** | **Internal State** | | + | |
- | | Text to speech | Gesture execution | Move limb | Grasp/Place object | User recognition | Face detection | Speech recogn | Localization | Obstacle avoidance | Battery status | | + | |
- | | Non-verbal sounds | Lip sync | Follow person | | Obj recognition | Gesture recognition (simple set) | Non-verbal sounds | Locate person | Locate obj | Competence execution monitoring | | + | |
- | | | Facial expression | Path planning | | | Emotion recognition (simple set) | | | User proximic distance sensing/control | | | + | |
- | | | | Gaze/head movement | | | Body tracking | | | | | | + | |
- | | | | Expressive behaviour | | | | | | | | | + | |
- | + | ||
- | Some competencies are dependant on others, such as facial expression which will require a face detection competency to operate. The computer vision competencies are to be concentrated on at first. | + | |
