“Square Battle” Competition Rules
BDS Robotics Engineering Challenge
The needs of the creators and producers are highlighted in today’s global
economic development. Clearly, we need today’s students become tomorrow’s
scientists, engineers and problem solving leaders.
Many organizations are planning new projects to attract and encourage
youngers to study science and technology. Many people think that ROBOT is
the powerful platform to attract and keep the attention of young people. In the
age of intense competition, the robot has great charm, it reflects in the brain
storm of the application of physics, mathematics, computer programming, digital
prototyping and design, problem solving, team work, and leadership. In the effort
of schools, voluntary organizations, companies and government, the potential of
the student in science, technology, engineering and mathematics will be excited,
to help them to find their own value.
The BDS robot is the next generation of education and competition
robotic products, and the BDS Robotics Competition is an excellent
educational robot competition. Although currently the world has many robot
competitions, the BDS robot user group shows a strong demand to organize and
participate in the convenience and economy of the new challenges of
competition. Asian Robotics League sincerely hope to meet the needs of all
BDS robotic users, to attract, to nurture and to develop candidate engineers for
solving the future problems.
BDS Robotics Engineering Challenge “Square Battle” is an exciting and
animating game, which can provide the participants a high tempo challenge. The
2
time of each game is 2 minutes and 20 seconds. Each game is divided into two
different types of competitions: programming autonomous game and manual
game. The matches are designed for two Alliances –one “red” and one “blue”-
composed of two teams each, compete in each Match. Teams will be in the
same field, to take and carry the balls, to put into the gate to make the game
score. During the “Square Battle”, the teams will develop many new skills to
cope with all kinds of challenges and obstacles. Some of them can be solved by
individual, but some can also be solved with teammates and coaches together.
All teams will make joint efforts to build a BDS robot Alliance, where they can
meet other teams, family and friends. Through the Match, the students not only
complete their match robot, but also enhance their understanding of science
and technology, and learn how to use them to positively impact the world
around. In addition, they can cultivate life skills, such as planning, brainstorming,
collaboration, teamwork, leadership, research and technical skills.
