o Built in test
o Robot data recorder that tracks information during the robot's life.
o The plastic structure/frame of the Roomba
o The cleaning assembly includes the pivoting self adjusting frame
that supports the brushes, brush guard, brush motor and gearbox.
o Dirt that is being picked up by the Roomba
o A sensor that relays information to the pcb
o An IR avoidance beam that ensures the Roomba does not bump
into it. Present in the Home Base and virtual Wall
o The self charging station
o A wave of light with wavelengths greater than those of visible
light (0.75 and 1000 µm
o Semiconductor light source that emits visible light or invisible
infrared radiation.
o Capable of moving or being moved readily
o A systematic escape behavior that the robot enters when it thinks
it is stuck. The robot senses that its front wheel is not turning and
abruptly changes course with a rapid spin.
o Pulse width modulation
o The frequency range from 10 kHz to 100 GHz used for
transmitting data, audio, or video. RF passes through walls.
o Room Confinement (reference to the omni-directional IR sensor
that sits on top of Roomba's bumper)
o Refers to things that are not moving or changing
o The physical means and method of interaction between users and
products
o Is not physical
. IR does not pass through walls.
