Help DPRG’s Robot Art Team!

DPRG has fielded a team in the robot art contest conducted by The submitted art pieces are the result of efforts by team members Doug Paradis, Ray Casler, and Steve Rainwater. Over the last several months, they have been diligently working at RBNO to create two art painting robots, artBot and drumArtBot.  ArtBot was used to produce Sumi-e art, while drumArtBot created a unique form of line art that appears similar to a modern art style.

Plastic Fastener Sumo Workshop

DPRG is proud to announce its annual Plastic Fastener Sumo Workshop. The workshop will be manned by experienced volunteers from the Iron Reign FTC team and DPRG members to help participants in the Roborama 2017 competitions (or similar) plastic fastener Sumo contest. If you need help with your Lego or Vex IQ system Sumo or line follower robot, this is where you want to be on Saturday, May 6th. The purpose of the workshop is to help competitors either get started or improve their Lego or VEX IQ based  Sumo or line follower robot.

The workshop will be held at the Dallas Makerspace located at 1825 Monetary Ln #104, Carrollton, TX 75006 (Map) between 10:00 AM and 2:00 PM on Saturday, May 6th in the Interactive Classroom. The courses will remain setup until 4:00 PM for practice after the workshop.

You must bring your robot or robot parts (don’t forget your battery and charger). No parts will be provided.

In addition to the workshop, the courses for other Roborama contests will be setup, so that they can be used to test robots and practice for the competition.

The event is open to everyone.



Monthly Meeting – April 8th

Meeting is at Noon, on Saturday April 8, at the Dallas Maker Space.

Members of Iron Reign FTC team will demo their award winning  robot at the meeting. The Iron Reign team has a long time association with DPRG. This year they won the Judges Award at the South Super Regional and will be competing in the state championship. Their robot has become more sophisticated each year. It will be fun to view the construction and hear the strategies they are using in this year’s contests.

 April is also the month where the 2nd part of the meeting is devoted to Roborama  contest practice. The courses will be available for anyone wanting to test their robots.

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


iMake 2017

iMake, a festival sponsored by the Fort Worth Museum of Science and History to celebrate the Maker movement, gives people a chance to be “a maker for a day”. The event collects demonstrations and on-hand activities created by a diverse group of organizations, and provides a venue for sharing them with young children and parents.

DPRG  manned a five table exhibit with interactive demonstrations of robots, Kinect, CNC drawing, 3D perspective tracking, LiDar, automated xylophone, Roborealm modeling, manual driven robot arm, and 3d printing.  Also, Big Robie made an appearance, all bright and shiny for this year’s event season.

The booth was crewed by Steve Edwards, Eric Chaney, Carl Ott, John  Kuhlenschmidt, Ray Caslier, and Doug Paradis. The all day event occurred on April 1, 2017.

Monthly Meeting – March 11th

Meeting is at Noon, on Saturday Mar 11, at the Dallas Maker Space.

DPRG Team wins Collidathon – Entrepreneurs IoT Hackathon

After DPRG  team’s success at the AT&T Hackathon, other DPRG members decided to try their hand in a similar event. They received their chance with Collidathon, an IoT hackathon event orientated towards entrepreneurs. The event was spread over two weekends (Jan 21 – Jan 29, 2017) and offered a spot in the Collide Village Incubation Program to the top 3 teams. Approximately 250 people initially participated in the event, and 14 teams were selected to advance to the second week of the competition. The DPRG team took first place in the competition, besting all other teams.

The team had to abandon their initial project idea after market analysis showed that idea to be in an area with many competitors. They joked that they would have to name their company “Red Ocean Security” due to all the chum in the water. Their second project idea turned out to be in a much less explored area, hence their company name of “Blue Ocean Technology” or BOT for short.

The team consisted of DPRG members: Carl Ott, Thomas Ericsson, Steve Edwards, and Jian Shi. Also on the team was Gary Ramsey (not in the picture above), who is not a DPRG member.

DPRG Hackathon Team Advances

DPRG’s own Hackathon team of Jain Shi, David Ackley, Omar Barlas, and Carl Ott have successfully advanced to the next tier of the AT&T IoT Hackathon. They are one of four teams in the nation to be invited to compete in the Mechatronics challenge at the AT&T Developers Conference in Las Vegas held in early January. With their selection, AT&T has provided help with airfare and travel expenses for two members of the team. The whole team plans to go to Las Vegas and they are sharing the cost. If they place in the top three teams, they would win a nice cash prize. Wish them luck!

The team will be discussing the Hackathon experience and their project at the December 10th, 2016 DPRG monthly meeting.

DPRG Hackathon Team – Wins AT&T Mechatronics prize

It started with an email from an AT&T Dallas Hackathon organizer inviting DPRG to participate in their November event. A group of DPRG members quickly joined together to form a team. The Hackathon lasted an evening (Nov 18th) and a day (Nov 19th), with the option to work through the night. The team developed their project idea fairly quickly, but then wasted the first evening chasing false paths of hardware choices  and software packages. The next day with clearer minds, they were able to develop a prototype that they presented at the end of the event.

The attending crowd and judges received the presented prototype with interest and enthusiasm. A little later the team found that they had won the Mechatronics prize of $2500 and become semifinalists for the AT&T Invitational at their annual Developer Conference in January. The team is busily developing their idea and preparing a video for submission to this next tier of competition. Wish them luck!
