Intel & Carnegie Mellon University Presented by Tim Haines HERB 1.0 : Home Exploring Robotic Butler
2
Ideal Uses for Assistive Agent Assist elderly or disabled Doing jobs currently done by service animals Cleaning Washing Dishes Laundry Ironing Moving heavy objects
3
Challenges to Operate in a Human Environment Efficient navigation and mapping Robust object recognition and pose estimating Sophisticated trajectory planning All done in unstructured constantly changing environment
4
The First Solution!!!
5
Principles of System Architecture Unlimited computational power is available This is achieve by using on board and off board computing Sensing and planning algorithms should require minimal human input Allows for the robot to adapt to new environments
8
Object recognition using sift Flea- Locating objects Narrow View, Large depth of field Dragonfly-Manipulate objects Wide View, small depth of field
9
Checkerboard Localization Found to be better than using the laser Down side Slow, taking 10 to 30 sec Needs at least 3 checkerboards in 1 image Tried children's drawings, Failed
10
Navigating using GATMO Generalized Approach to Tracking Movable Objects Two part maps Static Lists of objects
11
Classification
12
Vision
13
Planning Opening doors Planning based on Kinematics, no physics Often Herbs fingers would jam into the door causing a stall
14
