Over the weekend of March 6, Harker sixth graders Chelsea Liu and Andy Zhang (pictured right and left above, respectively, holding their teams’ trophies) delivered great results at the Northern California VEXIQ Middle School Regional Championship robotics tournament. Liu’s team, Tetrahedron, took second place overall, qualifying it for the world championship to be held later this year in Dallas. Zhang’s team, known as Season Stealers, was in an alliance with Tetrahedron and took second place in the teamwork challenge, which also earned the team a trip to the world championship.
