On Saturday, February 11th, we participated in a qualifying tournament at Quinsigamond Community College in Worcester, MA. We had given our robot a complete overhaul in design following the previous tournament so we were eager to see how it would perform during competition. After observing a number of matches played by many of the robots, we realized our robot was the only one with the capability of picking up two of the orange cubes at the same time. In addition, our robot can pick up five stars when they are clumped together. Though we were not so sure how our new robot would perform in competition, we believed our robot would do fairly well. We wanted to do well so we could experience what it would be like to be in the top tier after the qualifying rounds and to be able to choose our alliances for the elimination rounds.
For our first match, our alliance partner did not show up but we still won the match. Winning the first match was encouraging and gave us hope for a successful day. The running stats showed we were in first place for a period of time. We lost only one match out of seven and even that match was very close. We were among the top ten teams out of forty nine the entire day. We were in third place at the end of the qualifying rounds.
When we were not involved in a match, we spent our time interviewing the other teams to learn as much about the strengths and weaknesses of their robot. This is called “scouting” and was very helpful when it came time to choose a team to be our alliance for the elimination rounds. Not only do we learn about the other robots but we also get acquainted with members of other teams.
During the quarter finals, our alliance lost the first of three matches unexpectedly. We won the second match and then called a time out to adjust the programming of our autonomous program before the third match. Changing workable code without the opportunity to test it out was not a good idea. The robot jammed under the fence and was rendered useless for the remainder of the match. We learned a valuable lesson. We lost our opportunity to move on in this tournament. Now with two more weeks to revise our robot and our strategy, we have established and agreed on a clear plan to have the best robot possible ready for the Championship Tournament March 4th and 5th.
We are back! Read about how we have improved our robot for even greater success as we go to our next competition at Quinsigamond this Saturday:
Our first design (shown above) consisted of a pitchfork and backboard, which allowed us to scoop up to two stars and dump them over the fence. While this design was great for winning at the qualifiers, it felt sluggish and it couldn’t toss cubes over the fence reliably.
We went through a design process and came up with Yana’s Revenge, a grabber style arm that can easily grab cubes and up to six stars. Yana’s Revenge became our main design because it was much more capable at completing the tasks. It can also clap, so that’s nice.
This became our design of choice because it has a fixed bar in the middle that works with both motorized side arms. Using our controller, we can make the robot pick up as many as four stars reliably and also clap. We can also control each side arm independently, giving us improved control. Below are pictures of the new design.
For the next week we will be preparing for our competition at Boston University Academy. With a wonderful supply of light aluminum parts, and some minor changes to our wheel base, it will allow us to solve some major problems with our robot. We are also happy that two JV robotic members will be accompanying us.
The Starstruck challenge is a complex challenge that we are participating in for this robotics season. See what the game is all about (Click Me) This is made by Vex robotics, the platform for our league.
Our strategy with in the Starstruck challenge is base around throwing stars over as fast as possible, by use of a pitchfork arm. You can see a wonderful recording from our last competition (Click Me). The rounds begin with an Autonomous round where the robots follow pre-programmed commands. Don’t worry if they stop for five or so seconds, because after this, the driver controlled round begins.
After three months of productive work, the Williston Wildcat Robotics team had its first VEX competition of 2016-2017 season in Middletown Connecticut! Of the of 10 matches played, the team had 4 victories and 1 tie. We made it to quarter-finals! A good start, but we have more modifications on the way!
There were 41 teams competing and 24 were selected to participate in the elimination rounds. A match consists of four robots, with two teams allied and competing against the other two teams. There are many ways to score points. The allied teams work together to use the strengths of each robot to maximize the number of points they can score. Each team is scheduled for six matches throughout the first half of the day with different allies and opponents each time. In the second half of the day, the top eight teams have the honor of choosing the allies they want to compete with. These events not only showcase the engineering that goes into each robot, but also effective collaboration among the teams from different schools, which is very cool!
Our entire team was present plus another interested student, Isi Donnelly, Mr. Matthias, and I. The team members are Matthew Nguyen, Kohmei Kadoya, Andrew Pellegrini, Milo Servin, Alex Marwaha, Gabriel Davila Bustamante. This year’s team members are in grades 7-10.
Our next tournament will be at the same location on February 13. The third event will be on Feb. 27 at Middletown HS in Middletown, CT.
Hello and welcome to Williston Wildcat Robotics’ Blog! Periodical updates will be made to inform you on events, tournaments, pictures, and technological news that affect today’s society. This year, our young programmers and engineers will be attending the VEX Robotics – “Nothing But Net” challenge. Below is some footage describing the main competition and rules, as well as an actual match.
