A CONTEST-ORIENTED SYSTEM FOR LEARNING
INTELLIGENT MOBILE ROBOTS
ABSTRACT
A contest-oriented system for undergraduate students to learn implementation
skills and theories related to intelligent mobile robots is presented in this system. The
system, related to Micro mouse, Robot race, and line-maze contests was developed by
the embedded control system research group. It targets both those students who have to
earn credits for a one-year special topics course and those who are just interested in
making robots, and it is designed to motivate them to learn digital motion control, path
planning, attitude correction, curvature detection and maze-solving algorithms. The
students begin by getting acquainted with the development environment of
microcontrollers, the characteristics of different sensors, and servomotor control
techniques. Having learned these basic skills, they acquire further specific advanced
skills and proceed to design their own mobile robots to compete in contests. The special
topics course students’ robots must pass examination by five teachers. Blogs and a
wikiWeb site for recording students’ progress and experiences enhance the system’s
learning outcomes. Although not every student wins a prize in the contests, student
feedback still shows that the contest-oriented system did motivate them to acquire the
skills necessary to build and operate intelligent mobile robots.

Description
The line-following robot devised in this article for educational purposes includes
not only accurate line detection algorithms with analog outputs of reflective optical
sensors, but also home-made encoders, which help record all information about the
racing track. The firmware can then plan profiles for the fastest run.
Line following robots is self-operating robots that move along a line on the floor.
In addition to the intelligence of judging precisely where the line is, of memorizing the
racing track patterns and of speed command profile planning for motors, the
mechanical parts and design of the line-following robot are also important to reduce the
effect of weight transfer and to prevent skidding when making turns at high speeds.
According to the experience of the micro mouse world champion the turn speed is a
decisive factor in robot speed contests. To make a line-following robot with a speed
faster than 1m/sec even when it is making turns, the correct prediction of the line
position is a key factor.
Algorithms which are able to predict accurate line position depend heavily on
the assumption that reflective optical sensors have similar output characteristics. It is
also found that the spacing between reflective optical sensors and the distance between
the reflective optical sensor and the ground are important factors for line detection
algorithms to work accurately. Therefore, calibration of the reflective optical sensor
outputs is an important procedure for a fast line-following robot. An automatic

calibration procedure, which uses a pulse-width modulation technique to adjust the
light emitted from light emitting diodes and to simulate the reflecting conditions of 20%
and 80% of grey surfaces, is proposed in this article to remedy the problem.
The other requirement for line-following robots to run as fast as possible is its
ability to memorise what the racing track is like so that the robot can plan the speed
command profiles for its motors for straight lines and curves. Because of the weight
transfer effect, the speed on curves should be slower than for straight lines to prevent
skidding. Therefore, the line-following robot should not only differentiate curves from
straight lines, but also know the lengths of all the straight line segments. This is why the
line-following robot described in this article is equipped with a quadrature encoder.
How the encoder is designed and the algorithm used to calculate the lengths of all the
straight line segments are also discussed in this system and it was experimentally
verified as also reported in this system.
The robot, used for contests and laboratory exercises, consists of a
microcontroller dsPIC30F6011, dual H-bridge dc-motor drivers, an RS232 port to
communicate with a PC, an LCD display for debugging, an in-system programming
(ISP) port for downloading programs from a PC to the 48K byte flash memory, 9 A/D
ports for accessing the sound and reflective optical sensor circuit signals and an encoder
wheel. The necessary integrated development environment and C-language.

What is IEEE?
The Institute of Electrical and Electronics Engineers or IEEE (read eye-triple-e) is Incorporated in the State of New York, United States. It was formed in 1963 by the merger of the Institute of Radio Engineers (IRE, founded 1912) and the American Institute of Electrical Engineers (AIEE, founded 1884). A membership organization comprised of engineers, scientists and students that sets standards for computers and communications. It is a nonprofit organization with more than 365,000 members in around 150 countries.
The IEEE describes itself as "the world's largest technical professional society -- promoting the development and application of electro technology and allied sciences for the benefit of humanity, the advancement of the profession, and the well-being of our members."
Why IEEE based projects?
It grantees for standard
It assured latest solution for problems
It delivers new patented technologies at an ever-increasing pace
It access world-class technical information provided by the IEEE and cut down your
research time.
