Monte Carlo localization - Wikipedia, the free encyclopedia - 0 views

  • particle filter localization
  • typically starts with a uniform random distribution of particles
  • hopefully most particles will converge to where the robot actually is.
  • ...19 more annotations...
  • environment is static and does not change with time
    • Filip Bártek
       
      We also need to capture the robot's velocity in the state (pose) in case the robot has some momentum, so the three parameters may be not enough for a 2D robot.
  • assumes the Markov property
  • position and orientation
  • particles are uniformly distributed over the configuration space
  • Given a map
  • every time
  • every time
  • motion_update
  • sensor_update
  • sensor_update
  • some noise is applied
  • It now believes it is at one of two locations.
  • The robot has successfully localized itself.
  • actuation command
  • no actuator is perfect: they may overshoot or undershoot the desired amount of motion
  • the motion model must be designed to include noise as necessary
  • Particles which were consistent with sensor readings are more likely to be chosen
  • possibly more than once
  • a robot becomes increasingly sure of its position as it senses its environment

Ray's Fred FLED Photopopper Tutorial - 0 views

  • It's practically impossible to solder the FLEDs straight using only your hands
  • This part is rather tricky because there's so little space between the Solar Engine and the 3300uF Cap. -- You can leave more space here if you like, but it just looks better if you keep it all nice and tight
  • Find two FLEDs with the same (or very similar) resistance
