At our first regional our robot Marvin achieved the ability to score both gears and balls during autonomous using computer vision, plus effective gear cycling and successful climbing. Marvin had a great first day, winning most of its matches and as such the team walked back to our hotel hopeful and expecting a lot out of the next day.
We had not realized, however, that we had managed to shred the belt of our climber. We did not realize this until it was too late and due to the hardship associated with finding the correct belt, we were unable to climb for much of day two. This led to us losing our first few matches, as climbing is worth a substantial amount of points – dropping our rank from top 8 to the later teens.
Fortunately Team 6413 Degrees of Freedom from Chandler, AZ, decided to take in Marvin due to our ability to score balls and gears in autonomous as well as our impressive defensive capabilities. However, both of our alliance partners had parts of their robots break almost as soon as the match began, leaving Marvin the only robot left alive on the field. Although Marvin was outnumbered three to one we still put up a honorable fight and although we lost, we felt satisfaction from Marvin’s performance.

We finally got our climber working for the long-anticipated Duel in the Desert. The climber was able to pull up the robot and it works by latching onto Velcro, and is deployed with a spring and pneumatic cylinder.
After a slow start, the VEX team is making progress toward a solution to the Starstruck challenge. Terry provided some much needed wrench turning over the last week to help get caught up to a challenging schedule. Ethan and David tackled the lifter arm. Howard and Mike provided a first cut at the software.
The video shows the drive control working as expected after getting the motor polarities correct; and the position controlled lifter arm is functional, but needs more power, higher torque gearing, or some rubber band assistance.
The team expects to have that solved in the next couple of weeks, including a first cut at the autonomous mode.
We have 5 Vex spots, 4 Pumpkin Toss spots, and 1 FRC spot.

The team also seeks more mentors to teach engineering concepts to the students. If you can volunteer your time please let us know:
BEHOLD! The VEX Team has finally begun what we believe will be our robot for the 2016-2017 season. After a long-winded process of trying to figure out a strategy for collecting and delivering game elements, Jordan and I decided on a single-stage lifter.
Working in their underground bunker at CoLabs, the VEX Robotics Team shows off the toothy grin of their newly designed chassis. The realization that the long-arm catapult would be too long has them redesigning the chassis to accommodate a more compact lifter/thrower. Go team!
Thanks to Howard for finishing the code so we have the first two functions working (driving, pushing).
The Bit Buckets’ Vex team has started a new year! The game which they are playing this year is called “Star Struck.” But, with the team being Star Wars nerds, they decided to have a Star Wars introduction to their code! (Look at picture)
