Trying to walk through a maze is fun. But if you have to walk through it undetected, finish a game of chess, crack a laptop password and detonate a bomb — all of it under 13 minutes — the endeavour is one not many can complete.

Just seven out of over 50 teams at the College of Engineering, Guindy’s ‘Waves’ techno-management fest were able to get through their allotted tasks.

“The most important thing is to not get caught in any of the traps. There were six clues using which we had to find the password. And the maze was also interesting,” said U. Tamilazhagan, who along with team members, T. Tamilarasan, R. Sudharsan and R. Prasana got the prize for finally detonating the capacitor bomb. They also got through part two of the event, the treasure hunt.

The 31st edition of ‘Waves’ that concluded on Wednesday had five workshops and 30 events in which over 60 colleges participated.

At the project display, one of the interesting presentations was a vision-controlled hazard detection robot by a team from GKM College of Engineering and Technology.

The team members S. Sathyamoorthi, R. Shyamsunder and C.K. Swaminathan explained that the robot had a camera and gas sensors and could be used in mines to detect the presence of gases including methane, carbon monoxide and propane.

The team from Jeppiar Engineering College — G. Manoj Reddy, A. Dineshkumar and V.R. Siddarth — had presented the idea of establishing a renewable hybrid power generation system to supply to base stations.

Solar panels on the roof of the control room, micro twin wind turbines and turning off the tower in the night would help save at least 40 units a day, they said.

Students of Prathyusha Institute of Technology and Management showcased a project that displayed how power theft could be detected automatically using wireless technology.
