T-1 Day

After taking a brief, one day break, it’s back to building with only 1 full 24 hour cycle remaining until it’s hands off. As of right now, all that remains is wiring and the implementation of a camera and the newest code. The drive has been successfully tested and the rest of the mechanics are about to be enabled for the final troubleshooting session. The weather outside in SoCal is currently hailing and a majority of the team took a break to go outside and enjoy the rare phenomenon. We will be back with more updates after we finish playing in the rain.

T-3 Days Until Bag and Tag

With only 3 days left until the robot has to be finished, time is tight to finish the robot and add all of the finishing touches.

With a practice robot already completed and running, the competition robot is being quickly assembled in the same fashion. All of the major components have been mounted and all that’s really left is to finish up the wiring and push the newest code to the robot. The bumper is almost completed and the claw is being mounted to the arm.

As the next three days unfold, more updates with be posted on this site as well as on our twitter page.

R^3 Name Change?

As some of you may be aware, Reseda High School may be re-branding itself to Regent Charter High. So what does this mean for the Reseda Regents Robotics? The Reseda Regents Robotics team has a long-running history in Reseda, California that spans many generations of students. Since its foundation many years ago, the team has always flown under the flag of R^3. Our R^3 stands for more than our initials. It also stands for our values of Responsibility, Resourcefulness, and Respect. Due to this long-standing tradition, the sound of the name, and the values it stands for, Reseda Regents Robotics is here to stay.

2018 FRC Powerup

Welcome to the Reseda Regents Robotics first post of the 2018 FRC season.

The Game
This year’s game, powerup, consists of multiple yellow cubed that are to be carried around the field and deposited at one of two switches and one scale. The objective is to weigh down your side of the switch/scale with pieces to earn points. Points are earned on a per-second basis when controlling a switch, scale, or both. At the end of the match, players can climb the middle scale for extra points and if all three climb, they can challenge the boss and earn 1 ranking point.

There are multiple powerups available and multiple strengths per powerup available in exchange for cubes. Each powerup has space for 3 cubes underneath it. The amount of cubes inserted determines the level of the powerup. The available powerups are force, boost, and levitate. Force takes control of the scale, switch, or both depending on what level of powerup, boost doubles points from scale, switch, or both depending on the level, and levitate gives one allied robot a free climb. Only one powerup may be used at a time and each powerup may only be used once.

The Plan
The Reseda team is already hard at work engineering the ideal robot for this challenge. You can view the progress made in the team documents on the FRC Files Page and on our twitter page.

We look forward to a strong 2018 year and wish the best of luck to everyone!

VEX Mecanum Vs. FRC Mecanum

The 4” VEX mecanum wheels strafed three Sack Attack sacks (that is, 15.5”). That’s about 6:5 strafing distance to wheel circumference. More tests were necessary to make sure that ratio exists on the FRC robot as well.

How to get AndyMark 775 motors with 100:1 Vex Pro Versa Planetary Gear Set to work

These were our tests to try to get the VEX Pro 100:1 Planetary Gear set to work with the AndyMark’s 775 motors.  These motors will be used for our intake rollers.

  1. We took the gear box apart and looked at the individual gears to see if anything is inside.
  2. We decomposed the gearbox and tested the motor again. Unfortunately, that did not fix the problem.
  3. We tested the motor with a power source.  A 12V battery gave different results than a power source that is plugged into the wall.
    1. Plugging it into a wall power source gave a significant decrease in energy It was enough to run the motors without the gearbox.
    2. When the gear boxes are connected the motors, the motors will then not spin.  This lead to the thought that the gearboxes have too much torque for the motors to spin.
    3. Luckily, when plugging the motor and gearbox to the 12V battery, it worked better.  This may be due to a more consistent feed of electricity through the battery rather than the Power Source.
