mobile robots full report
Post: #1

Project Definition

To design a mobile robotic system that will
traverse through a maze with arbitrary
obstacles and transmit information to a PC that
will graphically display the robotâ„¢s telemetry
information and maze layout.

Project Objectives

Navigate/Collect information within maze
Traverse a closed path within maze
Transmit information using transceivers
Process and display received data
Exit maze

Project Specifications

Altera Board
Drive Train
IR Sensors
PC Application

Altera Board

Controls the robot
Interface to all modules
Modules are connected through
expansion header pins
Built-in 7-segment LEDâ„¢s, push-button
switches, and DIP switches for testing
Programmed using VHDL

Drive Train

Consists of 2 modified servos
with wheels
Drive Train control logic
provides 8 directional settings
and 4 speed settings
Servos are driven using PWM
Speed controlled by altering
duty cycle

Ultrasonic Rangefinder Sensors

Consists of 3 rangefinder
Determines range to objects
Returns hex value, which is
interpolated by software
Actual effective range
3cm “ 89cm
Actual precision inconsistent,
thus streaming buffer
implemented in software

Real-World Application

Plant Automation
Military Weapons
Home Appliances
Automated Medical

Mobile Robots
Why do robots need to move?
What defines a robot?

• Sense – a robot has to take in information about its environment
• Plan – a robot has to use that information to make a decision
• Act – a robot needs moving parts to carry out commands
What ways do robots move?
• Rotate
• Convey
• Walk
• Swim
• Fly
• Reach
• Bend
• Poke
• Roll
Manipulative Movement
• Robots that use an arm, belt or other means to grab and maneuver objects
• Mobile Movement
• Robots that can move from place to place
Why go from place to place?
• Transport goods and materials
• Carry messages
• Get there faster
• Do a task while you’re getting there
or when you get there
• Collect information about what’s there
• Get away from something
• See if you can!
• Most robots get around by rolling
• Walking is hard – it requires balancing
• Swimming only works in water
• Flying requires a lot of speed and energy
• Wheels and treads make moving over ground easier
• They provide stability with multiple points that touch the ground
How do rolling robots work?
• Sensors
• Motors
• Wheels
Main Components of Robotics
• Build – Mechanics, Mathematics, Physics
• Program – Building behaviors
• Test – Multiple trials
• Communicate – What did you work on or accomplish? What conclusions did you come to?
• Building
• Gears and axles
• Beams and connectors
• Motors and wheels
• Sensors and wires
• NXT programmable brick
LEGO® Pieces

• Building LEGO® Motors and Sensors
• Building LEGO® NXT
• Programming Behaviors
• Giving the robot behaviors
• Complex behaviors are built from simple ones
• Programming
• Programming Screen Interface
• Programming Blocks and Functions
Testing Why do we test?
• Make sure it works!
• Understand what it can do
• Test everything multiple times to determine the repeatability
• Use the robot to test other phenomena
• Testing
• When we test, we take data (numbers)
• We write our numbers down in organized charts
• We write down everything we can about the experiment
• Look at our data after we’re finished
Why is communicating your design so important?
• If no one knows what it is, how it works, or why it’s cool, why would they want to buy it?
• When it is well-documented, other people can build on what you have started and create even cooler technologies!
• Communicate
• Experiment worksheets and log books
• Presenting our work
• Sketching and describing ideas so teammates can understand too
What is Engineering?
• Problem solving
• Teamwork
• Time management
• Testing
• Doing it over if it doesn’t work correctly the first time!
• Engineering Process
Personal Assistant Robot
• We will be making a mobile robot to help out in the classroom
• We will run tests on the robot to determine its capabilities
• Before it can do complicated behaviors,we have to teach it simple ones
• But before we program anything, we need to build
