typically starts with a uniform random distribution of particles

hopefully most particles will converge to where the robot actually is.

  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.

Cancel
no actuator is perfect: they may overshoot or undershoot the desired amount of motion
...

Cancel
the motion model must be designed to include noise as necessary

Particles which were consistent with sensor readings are more likely to be chosen

a robot becomes increasingly sure of its position as it senses its environment

Servos are DC motors with built in gearing and feedback control loop circuitry. And no motor drivers required!

智能不仅仅局限于大脑。在整个控制过程中，大脑，执行器以及传感器都对产生我们认为是智能的行为有着非常重要的意义。这就意味着，在定义机器人的行为时，你机器人的尺寸也要被考虑进去

The Ants are a community of cubic-inch microrobots at the MIT Artificial Intelligence Lab. There are two main goals for this project. The first is to push the limits of microrobotics by integrating many sensors and actuators into a small package. The second is to form a structured robotic community from the interactions of many simple individuals. The inspiration behind this idea comes from nature -- the ant colony.
