Permit “willing”, we will be at the usual location on Saturday morning.
Don’t scheme ways of defeating the competition. We are all working together to solve the problem!
No winners, no losers. Just learners.
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!
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.
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.
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.
We will have four courses.
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.
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.
Expect any and all weather conditions
Your robot will have at least these basic systems:
3) Direction Determination
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.
Parallax also sells pre-assembled IR sensors, ultrasonic sensors, tilt/acceleration sensors, etc. They are not unique in their offerings.
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!
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.
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.
Brian will be expanding the Colorado Robot Challenge on the CSGC website. This site will include answers to questions that various groups encounter.
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 (email@example.com) for more information.
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.
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.
They should design a platform – the unit responsible for movement
Make arrangements for a workshop at firstname.lastname@example.org – he won’t respond until after October 5th.
Look at different sensor options.
Allow the students to be creative and ….
Many designs are possible
There is still a lot of room for creativity.
