1. PhD Seminar inTeleoperation, Perception, & adjustable autonomy: How should we interact with robots? Mike Lewis
Spring Term 2003
2. What Should Robots be like? Anthropomorphic?
Conversational instructions?
General purpose?
Autonomous, unsupervised performance?
Problem solving?
Visual, tactile, proprioceptive, & auditory sensors?
3. Three Ages of Robotics Prehistory- 1980’s It’s all in the mind.. AI & planning will make smart robots work (STRIPS & Shakey)
1990’s It’s all in the environment..intelligence & usefulness will just emerge
2000’s It’s all in Human-Robot interaction.. If people and robots could just cooperate we could do great things together..
4. Shakey’s World(1) The original STRIPS program was designed to control a robot called Shakey.
Shakey was capable of moving, grabbing and pushing things, based on plans created by STRIPS.
5. Knowledge Engineering in Planning Shakey’s world
8. The other half is figuring out how they can cooperate in a way that is: Not completely controlled like an RC car
Not completely autonomous like Shakey
9. Domains I’m Interested in
12. Common Problems: Navigation Navigation, context, & situation awareness become difficult when cues to distance, location, etc. are degraded by:
narrow field of view
absence of cues to depth and distance
abrupt changes in field of view uncoupled to controlled motion such as turning a corner
13. Common Problems: Perception Even significant objects may be difficult to recognize because:
narrow field of view
absence of cues to depth and distance
Unusual/unexpected perspectives
Degraded imagery because of nonvisual spectrum sensors, poor quality images, low light levels, etc.
Following Examples from Robin Murphy’s Twin Towers Talk
14. Needed Image Processing and Object Recognition Technologies
15. Robots Compared with SearchCams SearchCams ~$10K, Robots ~$12K
SearchCams reach up to 5 meters
Robots reach up to 30 meters, averaged between 6 and 13 meters
Robots can put light on the object, prod it, look at it from different angles
Robots can go through more twisting tunnels
SearchCams and small robots take <1.5 minutes to set up and insert
16. State of Available Information what viewpoints have already been explored
example: boot?
no one rewound tape far enough back to catch earlier viewpoint which disambiguated the object!
17. Common Problems Autonomy In both domains we would like to have many robots/person instead of the other way around (like it is today).. To do this we’d like to have robots & humans adjust to each other’s needs.. E.g. Adjustable Autonomy
18. Seminar Topics Navigation & situation awareness
Egocentric/ exocentric/ & tethered views
Augmented Reality (e.g. synthesizing info to help maintain SA)
Wayfinding & suggested cues
Perception
Object recognition/attention direction
Control of gaze/ perspective driven locomotion
19. Topics (continued) Delegation of authority & AA
Robot cries for help & human roles in resolving impasses
Control of multiple robots..
