Alice, the Ant Robot
Alice is a robot that is made by a group of researchers in Argentina.
Alice is about 2cm x 2cm in dimension, and has two wheels with a
variety of sensors. Alice is able to sense in the following ways:
Alice can plan its reactions in the following ways:
Senses walls around it so that it does not run into the walls.
Senses light on the floor below it.
Observational computer senses the location of each Alice on the
course that the Alice robots are on.
Alice, after sensing and planning, acts on her environment:
Alice can determine the trajectory of motion from its current
location to the closest bright spot on the floor.
Alice can calculate motor output to move wheels such that she
is able to follow the determined trajectory.
While Alice by herself does not plan a path along the course,
together, the ant robots create a path from repeated movement
along the same path.
Alice is an ant-like robot that cannot do much on her own. However,
with the combination of a large number of ant robots, the ants can
decide to do something meaningful by creating and following a trail.
All above information was gathered from this
Alice moves her motors in the manner planned to follow the
The observational computer lights up a trail following each of
the Alice robots, and diminishes light that has not recently
been covered by a robot.
