High school students from across Saskatoon put their mechanical and electrical ingenuity to the test in a fierce competition among robot builders.
Eighty contraptions — built and programmed by students — fought in sudden death wrestling matches.
For each round, two sumo-bots were set inside a circle and let loose with the goal of pushing the opponent machine outside the ring.
The winner would move on. The loser would enter a consolation round for another shot.
The event took place on the Kelsey campus of SIAST.
Michael Banman, 15, a Grade 10 student at Walter Murray Collegiate took the overall championship.
Banman said he spent about two months on his device.
"It ranged from two hours, to all day sometimes," he said.
Along with bragging rights, Banman won $1,500 worth of credits for courses at SIAST.
The consolation round featured a surprise win by Amitoj Singh, a grade 12 student at Centennial Collegiate.
Singh said his entry was put together from left-over pieces of other robots — just one day before the event.
"I quickly put together every scrap piece that we had," Singh explained. "I had just the scraps to work with and I quickly put them together ... And I won."
