Cool Project: Tumblebug

with one comment

TumbleBugBlogDamien Kee, a VEX IQ and EV3 Super User, has created another cool project! This time he used one of his kids toys, the Tumble Bug Ball Drop, to test out how often the ball comes out of the left foot / right foot with a 50% probability. Damien says, “My boys got this toy for Christmas one year and I thought I’d put together a little device to check the probability of how it works. I used Ultrasonic Sensors with the EV3 and Colour Sensors (Proximity mode) with the IQ to keep track every time a ball went through the toy…. This would make a great experiment to run in class, not just with the Tumble Bug but all different types of kids toys.” We couldn’t agree more!

Damien used the VEX IQ and LEGO EV3 programmed in ROBOTC to run his tests. The programs figure out the percentage and display them on screen. Here is a full breakdown video of how the project was done …

 
 
 

 

Not only does this project allow for the practice of programming, but it gives the opportunity to assess variables when determining the results. Damien says: ”

What I love about doing these sort of extended investigations in class, is that rather than being a final conclusion, this now opens up a huge range of other questions and scenarios that you can test.

  • Why was there a difference?
  • Was the table level?
  • Do the different balls have an impact?
  • Does the placement speed in the mouth affect the results?”

Want to try it out yourself? Here are the code files Damien used:
EV3 RobotC –  EV3_tumblrbug.c
VEX IQ RobotC –  tumblrbug_VEX.c

Article: Robotic Competition Moves into Virtual World

without comments

AR-160119213The NWF Daily News in North West Florida published an article highlighting our Robot Virtual World competitions, focusing on our newest competition, the virtual Mini-Urban Challenge. The article talks about how our virtual competition is being used to help students test out their design before moving into the physical robotics competition. “Robomatter’s virtual world will test and exercise the Mini-Urban Challenge robots,” Steve Butler, the director of Doolittle Institute said. “The connection of our Mini-Urban ‘real world’ test environment to a bigger, simulated world will greatly enrich the experience of the participating students.”

Cool Project: VEX IQ Tetris

without comments

CP VEX IQ TETRISTetris is a beloved and well-known classic game that many of us have been addicted to at one point or another. We wait patiently for that perfect “Tetrimino” that will create a horizontal line so the board continues to move down so the game keeps going. Well, our latest Cool Project does just that, but on a VEX IQ brain and programmed in ROBOTC!

Petr Nejedly created the game as an experiment to see what could be done with the VEX IQ platform outside of robotics. He says, “I have coded it ad-hoc in one night. The code is pretty … short, not really pretty. 233 lines including (rare) comments.” When we spoke through email he mentioned that game is currently not random at all. “So, my son came to me, that he has an improvement to the program. That I should use this random() function, it will be more fun to play … Teachable moment! We have discussed, how a computer, a very exact instrument that always follows the same instructions and in fact only moves numbers here and there, come up with random numbers. What is a PRNG and how you have to seed it (srand()), what are real sources of randomness and what kind of issues such a lack of true randomness could cause in real world, besides lack of fun.” At this point, Petr said he would like to leave the actual fix to the curious readers/programmers out there to see what they can do with it. (Let us know if you do!)

Check out the game in action here:

Petr was nice enough to share the souce code, which you can download here. You can also read the original VEX IQ forum discussing the project here.

Cool Project: EV3 Security Tank

without comments

Cool Project EV3 TankKyle M. (aka Builderdude35) created a very cool project called the EV3 Krimzon Guard Security Tank! The tank is programmed in ROBOTC too, which was the first time Kyle programmed with our software. Kyle says, “[The EV3 Tank] features proportional IR beacon tracking, and a deadly-accurate turret targeting system. If that’s not enough, it also has a massive spiked steamroller on the front!”

 

 

 

 

Watch the tank in action here:

 

 

 

The tank includes an EV3 brick, two EV3 large motors, steam roller with spikes, a rotating dual-barrel turret, and three sensors! “There is a Mindsensors SumoEyes mounted on the chassis just above the steam roller (you will see the two red LED’s) that detects the targets in zones left, right or straight ahead. Just above that is a LEGO Infrared sensor that is used for beacon tracking. Lastly, there is a LEGO Ultrasonic sensor that rotates with the turret to confirm target acquisition.” Pretty awesome!

For a more detailed breakdown of the tank and code, visit his website here.

Announcing the Mini Urban Challenge for Robot Virtual Worlds!

with one comment

Mini Urban Challenge

We are very excited to announce a brand new Robot Virtual Worlds Competition, Mini Urban Challenge! Our new virtual simulation is based off the national competition sponsored by The Doolittle Institute, the Air Force Research Laboratory, and Special Operations Command.

 


 

The purpose of this competition is to design and program a robotic vehicle that can autonomously navigate a mini-urban city, using a virtual LEGO® MINDSTORMS® EV3 robot. The robot must enter the mini-urban city from a home base, travel through the city to assigned parking lots, park in any parking space in each assigned parking lot, and then exit the city by returning to the home base and parking in the home base. The robot should use the optimal path (shortest distance) through the mini-urban city to visit the parking lots. While in the city, the robot should obey traffic rules by stopping at stop signs and following standard right-of-way rules when other vehicles are encountered. You can find the official rule here.

Our new Robot Virtual World features three modes for the Mini Urban Challenge:

1. Practice Mode allows students to develop and test their code for the challenge, without worrying about scoring, penalties, or the clock.

2. Competition Mode is the standard version of the challenge field, complete with timing and scoring to reflect the real world competition.

2015-10-23_15-07-45

3. City Mode is an exciting, themed version of the challenge field, which also includes timing and scoring that reflect the real world competition.
