Autonomous Rover Robot with GPS RTK and Novel Control System – Monthly Meeting Topic – August 10th, 2019

Guest speaker Ross Melbourne will demonstrate his autonomous rover robot which uses GPS RTK for navigation, and a novel robot control system that employs Unity and Python. Ross’s robot control system has potential practical applications such as: robotic lawn care, security patrol robots, and autonomous delivery services. Ross’s talk will cover both the challenges and the lessons learned that he experienced while building the robot.

This is a great opportunity to see a sophisticated antonomous rover build.

The meeting is at the Dallas Maker Space and starts at Noon on Saturday, August 10th.

 

 





 


 

 

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. 

More information and rules to the contests can be found at:

Using an Android Phone with Your Robot – Monthly Meeting Topic – March 9th, 2019

For tomorrow’s meeting Iron Reign will share information about how they use Android phones to run their robots. The presentation will be informal and off-the-cuff. It will discuss improvements to their competition robot since last presentation, but the emphasis will be a coding walk-through using the Android framework provided by FIRST – the STEM program in charge of their competition.
The walk-through will show some simplified examples. If you want to follow along on your own computers, you can install the tools and starter code below:
1. Download Android Studio – this is a free development environment based on jetbrains, the java sdks will come along for the ride
2. Download the ftc_app starter framework from github – this is starter codebase
3. Compile the app. This needs to be done ahead of time because it will fail multiple times as it figures out new dependencies that need to be downloaded.
There is a fair amount of downloading in all of those steps. We won’t have time to debug the install process for those trying it on their own. However, if you are able to follow along live, we might have a way for you to test a very basic teleop program.  Iron Reign plans to bring some robot phones and show how to debug wirelessly. If it doesn’t work for you, don’t worry about it – if folks are interested we can follow up at RBNO.

After the presentation there will be a show and tell, with a Donkey Car demo.
The meeting is at the Dallas Maker Space and starts at Noon on Saturday, March 9th. 

Robot Showcase at DevFest 2018

Dev Fest Weekend (Dallas) was held on October 13th at the Microsoft campus in Irving. DPRG was there. The club presented a showcase of robots and competitions during the lunch session of the conference. Members demonstrated “Can-Can Soccer”, a competition where two robots autonomously collect cans from a 7′ X 10′ course and return them to their goal, and various levels of line following from simple to challenging. The showcase was viewed enthusiastically by many conference attendees with DPRG members fielding multiple questions about the robots and strategies used.

Below is a picture of members who participated in the showcase.
