RoboColumbus-2021 Results

DPRG’s RoboColumbus-2021 competition was exciting and successful, with over 30 attendees and 7 competing robots. In an exciting climax, 2nd place was taken by Raj Prabhakar in the very last run of the competition. This is the first year that RoboColumbus included remote location competitors. Pat Caron competed from Baldwin Ontario, Canada. This is definitely a contest feature we will be repeating next year. The local course was laid out by the competition’s site host, Steve Edwards, and he denies adding extra potholes. A special thanks goes to Trina Edwards, Steve’s wife, for hosting the event at their home and property. Trina made sure that the robots and their keepers all had lunch, snacks, and drinks throughout the day.

Competition Results:
Place        Robot Builder                       Robot Name
1st            Scott Gibson                          T.U.R.D.

3rd           Ted Meyers                             Skipper

A lot of video was taken at the contest, which will require much editing. Look forward to a highlights video and photo gallery in the near future. When available it will be placed on the site as a separate post.

 

RoboColumbus-Plus Remote Location Guidelines and Rules Update

The RoboColumbus-Plus competition page has been updated with guidelines detailing how to join this year’s competition from a remote location. DPRG hopes that the many friends and potential friends who can’t travel to the local Dallas competition can join by setting up a remote course and using Google Meet to participate in the fun and challenges of an outdoor rover competition.

The RoboColumbus-Plus rules have been updated to add a new contest category and challenge. Participants now have the option of running their robot in the “robot-planned” category and taking the 3-waypoint challenge. In this challenge, the robot must depend completely on it algorithms to complete the course with only 3 target waypoints. The robot’s owner is not allowed to pre-walk the course during the competition or use additional waypoints besides the 3 given by the judges.

Fall Competition 2019 Highlights

The FALL competition for 2019 has come and gone. It was casual, exciting, and a lot of fun. Great progress was shown by several competitors.

Some highlights were:

  • Ross Melbourne’s Donkey Car completed 20 flawless laps (score: 80) within the 5-minute time limit of the Donkey Car competition on a course with an inside boundary length of ~50 feet (course is visible in the image above) . Unfortunately we lost the video of the 1st run, but see the video for the 2nd run below.
  • Carl Ott, Ray Casler, and Clay Timmons were all able to finish the Challenge Line Following course with 4 interventions. Each competitor showing great progress from previous attempts. Carl was able to reach block 5D before requiring an assist.
  • Carl Ott debuted his modified version of the 2016 Club Robot in the Quick Trip competition, taking first place with a perfect score of 7 in a time of 14.77 seconds.
  • Scott Gibson continued to rule the 6-Can competition, collecting all 6 cans in 1:42 minutes.

Roborama 2019 Gallery

Nothing gets the enthusiasm going like a good robotics match. The enthusiasm at Roborama 2019 was epic. Everyone was excited and enjoyed themselves. 

DPRG would like to thank all the competitors that participated, all the members who helped manage the event, and our sponsors. A particular shout out goes to: Mouser, Pololu, Rev Robotics, and Tanner Electronics for their support. 

Here is a gallery of some of the sights at the competition. Click on the images to see an expanded view.

Roborama 2019 Pre-registration

 

Pre-registration Time is NOW!

With Roborama 2019 less than a month away (May 11th), it is time to pre-register your robot team. If you tried and ran into problems, those problems are now fixed. Try again. Pre-registered teams get the best pit area placements. This year’s competition has several contests that will test your robot’s skills. Come compete, win, and take home great prizes.

  • Plastic Fastener-only Sumo – a student only event. Pits your robot in a contest of strength and strategy as you attempt to push your opponent from the arena. 
  • Line Following – with contests for beginners through advanced competitors and a special student only contest. Tests if your robot can follow a line around the course.
  • Quick Trip – an open event. Can your robot go straight? Can it make a 180 degree turn? This contest tests a fundamental skill of your robot. Never been in a robot competition? This might be your contest.
  • Four Corners – an open event. So your robot can go straight and turn, can it maneuver a large square and come back to its starting location? How close can it come?
  • Table Top (classic) – an open event. This contest is for the daring. Your robot moves around a table top with nothing to keep it from taking the plunge to the floor as you perform three tasks.
  • Can-Can Soccer – an open event. Race another robot to collect cans while not getting confused or hitting your opponent.

RoboRama – 2018 Contests

ARM based Subsumption – Monthly Meeting Topic – August 11th, 2018


DPRG’s monthly meeting for August is on Saturday, the 11th, at the Dallas Maker Space. The meeting starts at Noon.

This month, long time DPRG member David Anderson will review recent upgrades made to his infamous “leaf blower” RCAT robot. Dave has completed a port of the robot’s subsumption architecture and LMX, a light-weight cooperative round-robin multi-tasking executive, to an STM Nucleo F411 board. The result is a dramatic improvement in performance. David will also highlight a custom printed circuit board, a joint effort between Ron Grant and David, that facilitates signal and power breakout for clean wiring layout. David will provide details on how to obtain a copy of the board.

As part of the presentation, Dave will also touch on the subsumption architecture used in this and many of his competition winning robots.
