Movement
 Define Types of movement:
Locomotion – The ability to move from
place to place (move from place to place)
Localization – To perform functions in a
specific area (turn head)
Manipulation – To touch or move by
mechanical means (move other things around)
Cooperation - To work together
(two motors working together for movement)

specific when giving directions?
Write down the step by step
directions of how to fold a paper
airplane.
Created by Emily RCG Williams for the South Pasadena Education Foundation
16
What do we need
the robot to do?
 Moving: The robot must be able to control
some set of actuators to move how and when
we want it to. We must be able to reliably
place the robot anywhere we want.
 Sensing: The robot must be able to perceive
its environment through sensors locate
obstacles to avoid, and objects of interest
that we want it to interact with.
 Plan/Act: The robot must be able to make
decisions using its processor based on it’s
sensors and feed them to it’s actuators to be
able to move.
Created by Emily RCG Williams for the South Pasadena Education Foundation
17
What is a sensor?
 Takes readings from physical
environment and turns it into an
electrical message/signal
Sensors we will work with:
Touch- hit something and it react
Light- can sort by color or detect light
from dark
Sonar/ultrasonic- tells how far away
things are
Sound- tells how loud something is
Created by Emily RCG Williams for the South Pasadena Education Foundation
18
What is a processor?
It is the logic circuitry that
responds to and processes the basic
instructions that drive a computer.
A computer needs to be able to:
Receive inputs from the sensors, and
convert the sensor readings into
perceptions
Make decisions based on it’s perceptions
Created by Emily RCG Williams for the South Pasadena Education Foundation
19
What is a processor?
Continued
Use these decisions to change its
environment (or move itself in the
environment) using its actuators.
Each of the previous three things is
programmed by the user using a
programming language.
Takes readings from physical
environment and turns it into an
electrical message/signal Touch- hit
something and it react
Created by Emily RCG Williams for the South Pasadena Education Foundation
20
What is an actuator?
Takes electrical message and turns it
into a physical action. For example:
Electric motors receive electricity
which makes their axles turn. These can
be connected to wheels, which can make
the robot move
Pumps receive electricity which makes
them compress liquid through tubes
which can make a robotic arm move
around. This arm can push, pull, and lift
things in the world.

28
Ultra Sonic Sensor
Ultra Sonic sensor sends out a high
frequency chirp from one circle and
the sound wave bounces off an object
and returns to the microphone in the
other circle.
Because sound travels at a constant
speed ~1,125 ft/s the processor can
calculate the distance the sensor is
from an object and respond based on
the programming.

Sonic sensor fail?
Far away
