Students showcased their talents at Robocon 2014 Hong Kong Contest

On 22nd June 2014, 18 students of the Faculty of Engineering participated in the Robocon 2014

Hong Kong Contest. Two teams - SAPIENTIA (格物) and VIRTUS (明德) were formed to enter the

contest.

Members of these two teams showed HKU’s strength in gathering the best international talent.

Among the two teams were students from China and Hong Kong studying Mechanical

Engineering, Electrical and Electronic Engineering, Medical Engineering, Computer Science, and

Science & Education in the Faculty of Education.

During the preparation period, team members worked well together and cultivated ideas from

each other through extensive research. The teams enjoyed the benefits of members with

different backgrounds. They spent many hard working days and nights with the help of their

mentor, Dr. K.C. Cheung, who provided both guidance and support deemed very important by

his students.

All ready and set!

The theme of the contest this year – “A Salute to Parenthood” defined the match format and

rules. Each team has to build a “mother” and “child” robot. The “child” robot is guided by the

“mother” robot throughout the match to finish 4 tasks, namely the “see-saw”, “swing”, “pole

walk” and “jungle gym”.

Team SAPIENTIA won 3rd place in the contest, and as our both HKU teams shared the joy,

members insisted that they will join again next year, and will again gear up themselves

beforehand with better preparation.

The highlight of HKU’s teams was the use of jet propulsion technology on their “child” robots,

which was very unique to the contest. None of the other teams used the same technology to

power their robots.

The inspiration came from jet engines and rockets that use the same technology by blowing air

at high speed in a direction opposite to the direction of motion. As a result, the moving body is

propelled forward. According to the team, this requires precise control and a sensor fusion

system.

The advantage of using this jet propulsion approach was particularly seen during the “swing”

and “jungle gym” tasks, and gained the applause of all other teams on the court. At the end of

the contest, our teams were invited by the judging panel on stage to demonstrate the “jungle

gym” and “pole walk” tasks. It was a pleasure for the audience as no other teams on the court

were able to complete these two tasks during the timed matches. HKU’s “child” robot did not

fall short of everyone’s expectations. It literally “flew” its way up the ladder, and reached the

top landing within 2 seconds.

Chim Lee Cheung (Studying EEE, Year 2) represented the HKU team, demonstrating how to

use “jet propulsion” to power a robot up the ladder, and enjoyed the amazement of mouth-

opened audience.

Our teams described their participation in the contest a “glorious defeat”. They were pleased

with their participation, as the contest provided platform for exchanging ideas and experiences

with other students in Hong Kong.
