Event Description

    Ray's Wedding

  • Field:

    The Long Beach Museum of Art courtyard overlooking the Pacific Ocean, with 2 banks of chairs on either side of a grass covered and flower lined aisle. At the front of the aisle is a flower covered archway and a T shaped aisle to the right and left.

    Primary Function:

    With a white lacy pillow supporting 2 wedding rings, The robot drove down the aisle with the drive team flanking it on either side beautifully dressed in formal purple dresses. At the front of the Aisle, the robot turned right drove to the best man, and elevated the pillow for easy ring removal. The robot then proceeded all the way to the end of the right aisle T to await the end of the wedding. At the conclusion of th ceremony, it drove back down the aisle after the rest of the wedding party.

    Penalties:

    Unless the robot police showed up to cite the robot for being covered in flowers, there were no way to incur any penalties. It was a wedding after all.
  • Watch the video of the robot here.
  • If you would like to have a robot be YOUR ringbearer at your wedding, we are willing to rent it out. Please contact us at bagelbytes702@gmail.com. All proceeds go toward supporting the Culver City High School Robotics Team.

Coach's Notes

    It all started with a joking comment at the end of competition party. Wedding plans were being talked about and someone says "We could build a robot to carry the rings down the aisle." Everybody laughed, including mentor Ray and Katie, his wife to be which was the intention of the comment. Until... suddenly Mentor Ray's Fiancee Katie says, why not have a robotic ringbearer? From there the "Ringbearer Project" was born. We treated this as any other competition assignment. We held a "Kickoff" event to come up with design ideas. As part of that, we had to do some extensive testing. I know most people would think that rolling down an aisle does not need testing. However, our team is used to working on carpet, sometimes concrete, and occasionally bathroom wall surface. The grass surface of the wedding is completely unfamiliar to us. So using older robots with varying drivetrains, we ran them around a grassy area on the school campus checking maneuvaering and traction. We decided on a 4 wheel drive system under a tank drive control scheme. From there we also had to look at budget. Wanting to keep costs down, we used our supply of spare parts for construction. The chain drive was a necessity with only 2 spare transmissions available to make a 4 wheel drive system.

    The mechanism was meant as a surprise for mentor Ray. As a great supporter of pneumatically driven mechanisms, Ray constantly runs against the coach's completely irrational hatred of pneumatics. (It may be irrational, but not unfounded!) With plenty of pneumatic parts available, and several students expressing interest in learning, we decided to incorporate Ray's favorite subsystem and use it as a learning experience in case we need it for competition. (Not a chance!)

    The last problem came from size. The aisle would not be big and the robot would need to not look like a monster filling the aisle. So with a small footprint, the electronics board got split into two levels. So with 2 levels of electronics, and a smaller platform for the rings, the final look of the robot is something like a tiered wedding cake.

    The robot was completed the day before the wedding. (Of course it was, we're a robotics team, we never get anything done early) The plastic shell was installed and everything tested. The day of the wedding meant decorating. No wedding robot would be complete without flowers. Fortunately, the drive team of Arielle "Brownie" and Amaris "Noodles" have a lot of experience with flowers from years of decorating Rose Parade Floats. They created a miniature forest on the robot with ivy all around. I never imagined a robot covered in flowers, but it was an incredible sight to behold. It was a big hit at the wedding, being talked about by everyone. Ray and Katie loved it. This was the message sent by Mentor Ray:

    "Thank you to everyone who helped with F-R0D0. Katy and I loved it and it made our day truly special."
