Colorado Robot ChallengeYear 4

Saturday

April 10th, 2010

location great sand dunes national park
Location: Great Sand Dunes National Park

Permit “willing”, we will be at the usual location on Saturday morning.

goals
Goals

We are:

  • attempting to develop small autonomous robots capable of traversing harsh terrain as they move towards a central beacon.
  • providing students with exceptional training in a growing technological discipline.
let s look at the basic rules
Let’s Look at the Basic Rules

Don’t scheme ways of defeating the competition. We are all working together to solve the problem!

No winners, no losers. Just learners.

basic rules
Basic Rules

Maximum Mass: 1.5 kg

This is the mass of a small cat.

Please don’t add electronics to

cats and enter them.

Keep them small!

basic rules6
Basic Rules

A beaconing system will provide location information to the robots.

This signal will be used for tracking and sending information to the robot. Details will be discussed later in the presentation.

basic rules7
Basic Rules

No materials which could potentially harm the environment!

We want good publicity, not bad publicity. After the event, we will also clean the activity area.

basic rules8
Basic Rules

The robot must remain in contact with the ground!

The goal is to navigate the

terrain, not avoid it. Flying

robots will not be allowed.

overview of the event
Overview of the Event

We will have four courses.

Overview of the Event

Course 1 will be fairly smooth and lacking major obstacles. The purpose of this course is to illustrate the robot’s ability to find the homing beacon.

Overview of the Event

Course 2 will be essentially level, but will contain obstacles, natural or artificial. On this course, the robot will demonstrate its ability to detect and avoid obstacles while still homing to the beacon.

The obstacles will be sizable.

Course 3 will involve uneven terrain. This course will demonstrate the robot’s ability to make decisions regarding a safe route.

Obstacles may be present

Course 4 will be a nightmare, combination of all the course only at a harder level.

basic systems
Basic Systems

Your robot will have at least these basic systems:

1) Motion

2) Sensory

3) Direction Determination

the where am i question
The Where am I Question!

We will provide a base station beacon, details on the website. It will be capable of tracking your robot IF your robot requests to know where it is. It will sent back to your robot the angle between north and your robot. It should have an accuracy of about 5 degrees, more than adequate for our event.

off the shelf sensors
Off the Shelf Sensors

Parallax also sells pre-assembled IR sensors, ultrasonic sensors, tilt/acceleration sensors, etc. They are not unique in their offerings.

danger danger
DANGER! DANGER!

The fine sand at the Sand Dunes can find its way into your robot, causing it to stop working! Two years ago sand stopped the motors on a robot. Last year it stopped the ultrasonic sensors on a robot, leaving it “blind”.

If we are not alone, then you are not alone!

traveling workshops
Traveling Workshops

Randy Emmons will provide FREE beginning robotics workshops (Basic Stamp based) at your institution beginning in October.

He will also continue to interact, at their request, with your students through the development phase. This interaction can include expansion to the PIC microcontroller.

questions answered
Questions Answered

Brian Sanders at CU was “encouraged” to provide assistance with groups who chose to use the Atmel microcontrollers.

Both Brian and Randy can address questions on basic logic.

web support

Brian will be expanding the Colorado Robot Challenge on the CSGC website. This site will include answers to questions that various groups encounter.

money
Money!

CSGC has provided $2500 to be used as equipment money for this event. This is enough to buy a microcontroller and some basic sensors for 5 teams. Contact Randy Emmons (rwemmons@adams.edu) for more information.

colorado robot challenge philosophy
Colorado Robot Challenge Philosophy

We are working together on this project. It is not a contest. By working in teams, we increase the number of students exposed to this important technology. Different teams will take different approaches, allowing us to learn for each other. Share ideas! We, as a group, want to develop the best possible small, autonomous robots.

many omitted details
Many Omitted Details

While many details have been omitted, there is enough information for you to form teams (can be more than one team) at your institution. The students will need some time to brain storm robot designs. Their lack of technological knowledge is not a handicap; we are all involve with this project to learn.

where should your students start
Where Should Your Students Start?

They should design a platform – the unit responsible for movement

Make arrangements for a workshop at rwemmons@adams.edu – he won’t respond until after October 5th.

Look at different sensor options.

Allow the students to be creative and ….
