AJA Video TechTestJr

Many of the top fifth through eighth graders in the area gathered March 23 at two local technology companies to participate in the sixth annual TechTest Jr. math and science competition, sponsored by the Sierra Economics and Science Foundation.

The fifth and sixth grade test was hosted by AJA Video Systems in Grass Valley and the seventh and eighth grade test was hosted by Telestream in Nevada City. This is the first year that the test was offered at the fifth-sixth grade level.

More than 60 students from nine area schools, including Magnolia, Seven Hills, Mount St. Mary’s Academy, Lyman Gilmore, Forest Charter, NCSOA, Union Hill, Alta Sierra and Cottage Hill competed for bragging rights and STEM prizes that included six quadcopters.

TechTest Jr. is a math/science exam primarily targeted at high-performing fifth through eighth graders and it focuses on problem solving skills. The purpose is to provide an opportunity for students to demonstrate their proficiency at applying math and science knowledge to solve problems. Aside from acknowledging their skills, it’s intended to promote the development of more critical thinking activities in the county and to help prepare students for future exams of this type, such as the SAT and ACT.

It also helps students to prepare for the TechTest Merit Scholarship program in their senior year of high school to compete for over $15,000 in college scholarships. For more information on the high school test, visit

Holding the event at Telestream and AJA Video Systems was intended to show the students the type of opportunities that lie ahead of them as a result of their proficiency in math and science.

Telestream and Anna Greco, VP of Client Services Enterprise Products, were hosts to the students, providing tours of their facility, showing product demos and even having Andrew Haley (Telestream engineer and former Lyman Gilmore student) livestream student interviews to their Facebook page.

At AJA Video Systems, Stacey Wiederhold (AJA human resources) and Eric Gysen (vice president of engineering) were also hosts, providing lunch, product demos, tours and discussions for the fifth and sixth grade students.

TechTest Jr. is offered at no cost to participating students and is funded by donations and sponsorships by the Sierra Economics and Science Foundation (SESF) and by local businesses. It was offered this year as part of the county STEAM Expo and winners were announced at the Expo on March 25.

If any individuals or local businesses are interested in helping to support the 2018 TechTest Jr., please contact Dave Pistone at Anyone interested in getting a copy of this year’s exam (with answers) and previous years’ tests can visit the SESF webpage at and download the exams.

SESF Mentored Student’s Team Wins Spot in Regional Robot Competition (Updated 02-22-17)

1 Comment

UPDATE from Ryan, his Team is going the West Super-Regionals:

I wanted to update you guys about our performance this past weekend at the NorCal Regional Championship. Since Intel, we’ve made a lot of improvements to both autonomous and the launcher to increase the robot’s consistency. With these upgrades, we performed well in the qualifying rounds; in our last match, our alliance scored 205 points before penalties. Nevertheless, we faced some difficult opponents and were ranked 10th with a 3-2 record going into alliance selection. Unfortunately, we were picked by a poorly performing team to be a part of their alliance. Despite some close matches (we lost by only 9 points to the best team at the event!), we lost in the semifinals.

However, after watching the remaining matches with disappointment, we received the Motivate Award! Although normally not very coveted, this award qualified us for the West Super-Regionals, the next level of competition. This event includes a total of 72 teams from the 13 westernmost states and will take place March 10-12 in Tacoma, WA.

To help fund our trip, we’ve started a new wave of fundraising. We have a GoFundMe page (, and a PayPal donate button on our website ( We’d really appreciate it if you could spread the word. As the competition is in three weeks, we’d like contributions as soon as possible. 

By Russ Steele

On a Sunday morning, the Folsom Intel campus parking lot was quiet, just a few vehicles scattered across the tarmac. My wife Ellen and I had come to observe the Velocity Vortex robot competition sponsored by Qualcomm and supported by Intel.  Two competitors who are working together to promote STEM education opportunities for students.

As we approached the FM-7  Cafe, through a Courtyard, we could hear the rumble of voices spiked by cheers. Opening the Cafe door, we could feel the energy in the room roll over us. To our right were students cheering four robots, two red and two blue engaged in combat to see which team could score the most points. To our left a sea of tables with young men and women fine tuning their robots, and charging  batteries, as they waited for their turn on the scoring field, a 12 x12 foot instrumented open box with 1-foot high plastic walls.


The Scoring Field

We were fortunate to find some front row seats, in the staging area where the teams wait their turn in the scoring box. This position allowed us to examine the robots and their creators up close and still see the action in the scoring box on a large projection screen.  We saved some seats for fellow Sierra Economics and Science Foundation  Board member George Rebane and his wife, Jo Ann. We had come to cheer on the Nevada Union Team, Acme Robotics, lede by Ryan Brott, one of the students in the SESF TechTest Mentoring Program.


Acme Robotics Team

Shortly after George and JoAnn arrived the Acme Robotics team brought their robot 8367 to the staging area, and we were soon surrounded by the supporting parents, grandparents, and the team’s mentors Mike Oitzman and Michael Lewis.  Looking at the scoreboard it was clear 8367 was a strong competitor, having already won some of the early preliminary rounds of the competition.  At the end of the qualifying rounds robot, 8367 was #2 on the leaderboard.

The scoring is complicated and a challenge to write about without drowning the reader in the details.  For those interested, this video explains the scoring and the rules of the game, or check out the attached Velocity Vortex PDF Scoring Matrix.velocity-vortex-one-page

There are two phases in the live competition. The first phase is 30 seconds of autonomous operation, where the robot is controlled by onboard intelligence, followed by the controlled phase, where the robot is guided by an operator with a video game controller connected to an Android cellphone which was communicating with the onboard Android Phone. 

The competition is more than robotic combat on the scoring field.  As Mike Oitzman explained, the competition was set up to mimic a company start-up, where the students had to build a team, develop a plan, seek out funding sponsors, design and build their robot, and then develop a competitive strategy. Part of the evaluation is an assessment by the judges for the team demonstrating effective teamwork, creativity, good engineering practice and have a robust community outreach program.  

The NU Acme RoboticsTeam, includes hardware, software, marketing skills.

  •     Build team: Kellen Bodine (lead), Shawn Rashby, John Convis (CAD)
  •     Software team: Ryan Brott (lead), Kelly Muir
  •     Outreach team: Ivy Brott, Thea Pelayo

Hardware and Software Consulting

While this was clearly a team effort to win a spot at the regional finals, the autonomous routine written by Kelly and Ryan was a major factor in winning more matches than the competition.  They developed software that enabled the robot to position itself autonomously to capture the beacons on two sides of the scoring box.

Ryan said that mentoring by George Rebane, SESF Director of Research helped him to “gain some valuable insights” into robotic operations.


George Rebane and Ryan Brott

We could not stay for the final phase of the competition, leaving at the end of the qualifying rounds. The NU Acme Team finished the qualifying rounds in 2nd place and moved on to the semifinals.

“We easily beat the opposing alliance in the semifinals and went on to the finals where we unfortunately lost.” wrote Ryan Brott in an email. “The scores for both matches were very close (less than 15 points each). Fortunately, we received a prestigious [Innovation] award from judging that qualified us for the regional championships in three weeks.” 

The Regional Championship will be held on March 22rd – 25th, 2017 at the ARC Pavilion on University of California (UC), Davis campus. They expect 55 teams to compete, with over 2000 observers.  Ellen and I are planning to be in the crowd, cheering on the NU Acme Robotics Team led by Ryan Brott, an SESF mentored student.
