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.

“Build More Robots” Series

Dallas Personal Robotics Group (DPRG) is proud to announce the “Build More Robots” Tutorial Series.

What is it?
“Build More Robots” is a 5 part tutorial series that uses an inexpensive robot kit to teach people interested in robotics how to build robots.

Where is it?
All sessions will be held at the Dallas Maker Space located at 1825 Monetary Lane Suite 104, Carrollton, TX 75006.

When is it?
The series starts on Saturday, February 10th, at 12:15 PM (i.e., just after noon). The following sessions occur on the next 4 Tuesday evenings.

  1. Saturday, February 10th, starting at 12:15 PM. The first session will coincide with the DPRG monthly meeting.
  2. Tuesday, February 13th, starting at 7:00 PM
  3. Tuesday, February 20th, starting at 6:30 PM
  4. Tuesday, February 27th, starting at 7:00 PM
  5. Tuesday, March 6th, starting at 7:00 PM

Who can attend?
The series is open to everyone, however It is not recommended for children under 15. Attendees should be interested in learning how to build robots and have some knowledge of the Arduino environment. Strong programming skills are not required.

Do I need anything?
It is recommended that you buy the robot kit used in the series from Amazon, and use the video below to assemble it before the first session. You will need to bring a laptop with the Arduino environment (version 1.8.5) installed. Also, you should bring a small toolkit consisting of screwdrivers, pliers, wire cutters, and wire strippers similar to what you used to build your kit.

If you can’t complete the robot before the 1st session, bring what you have. Help will be available after the session to assist with such things as soldering. If you already have a similar robot kit, you can use it. The basic robot requirement is a Arduino Uno controlled two wheeled differential drive robot with an ultrasonic sensor. Later in the series, you will have to buy a few additional sensors, available from local stores like Tanners (around the corner from the DMS) and Microcenter, or online from Amazon.

What will it cost?
The robot kit is currently available from Amazon for ~$23. The extra sensors needed later in the series will cost ~$12. The Arduino software and the “Build More Robots” series are free.

What will we do?
The 90 minute sessions will be broken up into 3 thirty minute portions: Build, Programming, Techniques. The build portion will modify the robot to create new functions and the capabilities. These will be, “Moth” (attracted to light), “Table Top” (run on table without falling), “Wall Following”, “Line Following”, “Going Straight and Turning” (positional feedback), “Navigation/Mapping” (know location). The programming portion of the session will outline the software needed to create the different functions and give hints on how to improve programming style. The techniques portion will teach basic skills, algorithms, and tricks of the trade.

November Competition 2017

Get Ready!

DPRG’s annual November indoor competition for 2017 is Saturday, November 11th. The competition will start at 12:30PM at the Dallas Maker Space. Competitors will have access to the course at Noon. The contest for this year is the 6 Can (see rules). Also, a competitor is taking on the unbeaten DPRG Challenge Line Following course (see course layout).

In addition to the competitions, Carl Ott will run his successful Challenge Line Following Simulation for the video. There will also be demonstrations of club member recent projects and robots.

Everyone is invited to watch or compete. Members are encouraged to attend and support the competitors.

 

 

Monthly Meeting – August 12th

The next DPRG monthly meeting is at Noon on Saturday, August 12, at the Dallas Maker Space. This month there will be two presentations at the meeting.

Member Carl Ott will make the first presentation, which will touch on the use of  node.js and javascript in a robotics project from a beginner’s point of view. He will also give an update on his line following robot simulator. The simulator’s goal is to solve the DPRG Challenge line follower course that was first attempted in May of 2012. To date, no one has successfully completed the course. The course layout can be found at Challenge LF course diagram.

Member David Ackley will present how to prepare a STM32F103C8 minimalist ARM board, commonly called the “blue pill”, for use in the Arduino environment. He will also cover the new STMicro STM32 support package for Arduino. This initiative by STMicro allows programming of Nucleo boards and boards like the blue pill using the Arduino IDE.

As always, remember to bring and share your projects with other members in an informal show and tell session after the presentations.

Monthly Meeting – July 8th

The July DPRG monthly meeting is at Noon, on Saturday July 8, at the Dallas Maker Space.

Member Will Kuhnle is going to make a presentation on Closed Loop Feedback System (Servo) Design. He will be giving an overview of the design process including considerations taken for operating in discrete time, i.e., real-time sampled systems as we implement in our robot designs.

His design example system will involve a DC motor – certainly a common component in many our robotics control pursuits.

As always, remember to bring and share your projects with other members in an informal show and tell session after the presentation.
