Presentation Transcript

  1. Robots!

  2. Original Robotics • Stanford Cart • http://www.frc.ri.cmu.edu/users/hpm/talks/Cart.1979/Cart.final.mov • Asimo • http://www.youtube.com/watch?v=IlHVQ8bnuL8

  3. Embodied AI • Perception • Navigation • Manipulation

  4. Manipulators • http://www.eecs.berkeley.edu/~pabbeel/personal_robotics.html

  5. Sensors

  6. Sensor Types • Range -> ($6000) • Sound • Location • Orientation • Acceleration • Color -> ($43)

  7. Color Sensors (Cameras)How Eyes Work • 1 Rod & 3 Cones Response Wavelength

  8. So, 3 numbers define a color • 1 Rod & 3 Cones Response Wavelength

  9. Notice how much green covers • 1 Rod & 3 Cones Response Wavelength

  10. With Lights

  11. Lights Out

  12. RGB vs HSV • RGB values vary greatly with lighting. That’s a big problem. We use HSV instead:

  13. Cameras: Bayer Pattern

  14. The Point • It’s hard – why? • We have to work with the perception devices we can afford • There are some tasks that are harder/easier for us and for robots. The physics of the eye, mimicked with cameras, make it so.
