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.

Roborama 2018 Results

On May 12th, student and non-student roboticists tested their robots in a variety of contests at the 23th annual Roborama held by DPRG. Located at the Dallas Maker Space, the competition provided experiences covering the spectrum of thrilling surprise victories to the disappointment of mechanical failures. All contests at Roborama require that competing robots run autonomously.

In the student contests, Plastic Fastener Sumo and Student Line Following, competition was strong with competitors from four schools competing. The winning  robot in the Plastic Fasteners Sumo was  “Grizzly”. Grizzly’s owner received a complete VEX Robotics IQ Starter Kit as a prize for his accomplishment. This impressive kit was provided by VEX Robotics. Competitors from Grand Saline Middle School overwhelmed all competition in student contests. In Student Line Following, the winning robot “Thunder” traveled the 19.4 foot course twice in 54.6 seconds for a robot speed of 8.5 inches per second. Thunder’s owner choose a Leap Motion gesture motion control donated by private donor.  The 2nd and 3rd place winners in the student contests happily received great prizes from Pololu, Tanners Electronics, and other sponsors. There was much joy.

In the open contests, Scott Gibson continued to dominate. He won basic line following with “quicky” achieving a robot speed of 10.8 inches per second. He also won Wall Following, Four Corners, and Can-Can Soccer.  Scott achieved a start to finish distance of 0.428 inches in Four Corners. The student team, TechoKids, placed 2nd in Four Corners with a start to finish distance of 2.875 inches, a great achievement. Quick Trip was won by Doug Paradis with his robot “Clubbie”, which uses the DPRG club robot (v2016) design. Clubbie made some impressive runs in Can-Can Soccer. However, the robot’s success was limited due to an intermittent bad connection, later found to be a bad ground wire.

Monthly Meeting – March 10th (Competition and IMUs)

DPRG’s monthly meeting for March is on Saturday, the 10th,  at the Dallas Maker Space. The meeting starts at Noon.

The meeting will begin with a graduation competition for those who attended the “Make More Robots!” tutorial series. Participants will use the robot that they constructed in the class to compete in Quick Trip and Line Following contests.

After the competitions, DPRG member Ron Grant will present a short talk on low-cost Inertial Measurement Units (IMUs). The presentation will include a demonstration of  the MPU-6050 sensor using a low-cost and easy to obtain hardware module. This gyro and accelerator sensor chip has available orientation sensor code that can be executed on an Arduino or other suitable micro-controller.

November Competition Results – 2017

The big winner of this year’s DPRG November competitions, both indoor and outdoor, was Scott Gibson.

Both of Scott’s robots, CanMan and B.U.R.P., sported major improvements since their last appearance.  CanMan struggled in last May’s Can Can Soccer competition, taking third in the event.  However, at this November’s 6 Can event, the robot collected all 6 cans in 147 seconds.  Scott attributed the improvement to better software. B.U.R.P., Scott’s impressive outdoor rover also received major improvements. In Scott’s own words “B.U.R.P. has new wheels, drive motors, and custom designed H bridges, along with a new tail wheel assembly. I also completely revamped the sonar sensor unit with a new CPU and enclosure, and made more SW upgrades in all the CPUs than I can recall.”. B.U.R.P. achieved a perfect score of 9 in RoboColumbus Plus by stopping and touching all 3 of the course’s traffic cones.

In the 6 Can competition 2nd place was taken by VexNavigator, the robot that won Can Can Soccer last May. No major improvements were made to this robot which uses a Pixy CMUCam5 interfaced to a VEX Robotics IQ controller.  Third place was taken by ClubBot,  a robot using the DPRG club robot 2016 design. This is the first time a robot of the DPRG club robot 2016 design has competed in a contest. ClubBot collected all 6 cans in 232 seconds during the competition. However after the competition, ClubBot made a demonstration run with better tuned speed values and achieved a time of 165 seconds, which would have taken 2nd place. One of the features of the club robot design is how easily the robot can be reconfigured. The competing robot had a modified front end and sported 3 sensors (ultrasonic, IR gate sensor, and Pixy CMUCAM5). The owner, Doug Paradis, says that the competition spawned several ideas for improving the robot and he is anxious to start upgrading.

Roborama 2017 Results

On the morning of May 13th, the Dallas Makerspace bustled with the excitement of competitors in the 22th annual Roborama. Activities started with a tour of the makerspace. Many of the competitors and their guests had never seen a makerspace and the creative possibilities displayed by the work of various makers was a real eye opener.

Each competitor or team was assigned a table area in the pit room where they fussed with final robot adjustments while checking in. At check in, robots were measured, weighted, and inspected to insure that they passed competition rules. By the time check in was finished, everyone was very excited.

In the Plastic Fastener Sumo contest, the quality of the robots was good. The impact of the learning from the Sumo/Line Following workshop, held a week before Roborama, was clearly evident. The competitors that had attended the workshop had taken to heart the best practices they had learned. As always the competition was fierce with several of the matches not decided until a final push by the winner.

The Line Following contest, the second part of the student portion of the of the competition, also showed improvement over past contests, with the winning robots achieving higher speeds. The contest doesn’t require the robots to be made from plastic fasteners, however all student competitors used them.

After the student portion of Roborama concluded, prizes were rewarded to the winners of the student portion of the competition. Each winner received a DPRG trophy and choice of a complete robot kit or a gift certificate provided by our sponsors. Kits and certificates were provided by Pololu, Parallax, REV Robotics, Tanners Electronics, RoboRealm. and Richard Neveau.

Winners

The unrestricted participation part of Roborama consisted of the contests Big Table Top 2 and Can Can Soccer. In Big Table Top 2, a robot must complete 4 tasks. The tasks are: return a can to the starting zone, knock a can off the table, place a can into an overhanging box on the side of the table, and use the two remaining cans to form a line with the can in the starting zone that a yard stick can lay over (cans must be at least 8 inches apart). The top prize for Big Table Top 2 was won by a visitor to Roborama from Vancouver Canada, Markus Lampert.  His robot, Freddie, achieved a perfect score with a hitchless performance on the 1st attempt. Freddie has a hand crafted frame made of jig sawed plywood, a very tight design that incorporates several IR sensors, and a unique fin style grabber using flexible 3d printed claws. Markus is a member of the Vancouver Robotics Club (www. vancouverroboticsclub.org). Second place was taken by Doug Paradis with his robot, Little Andy.

Can Can Soccer, where two robots go head to head in an non-aggressive test to collect cans, becomes more competitive and exciting with each repetition of the contest. The winner this year was Doug Paradis and his robot VEX Navigator. Vex Navigator is built with the VEX IQ system. It incorporates a CMUCAM5 Pixy to identify cans. The Pixy is connected via a TI MSP430 LaunchPad  board, using the techniques published by James Pearson, in his documentation of the VEX IQ Sensor Reference. Second and third places were won by Ray Casler and Scott Gibson. Ray’s robot, Rainman, sported several new modifications. The modifications included a beacon system to allow determination of location after a collusion event. Scott’s robot, Can Man, usually a truly strong contender, suffered from a flurry of undetermined problems that hampered performance. Markus Lampert’s robot, Freddie, also participated. Fredde made a good show, but did not place. The final bout pitted VEX Navigator versus Rainman. In the ending moments of the bout, Rainman and VEX Navigator targeted the same can. Time ended with Rainman trying to catch VEX Navigator as Navigator snatched the can and placed the winning can into the goal.
