with one comment

The Robot Virtual World team has a fresh round of updates available for you. We’ve listened to your feedback and have made some changes to our Curriculum Companion, Sack Attack, and Ring It Up virtual worlds. Read on for more details!

What’s new in the Curriculum Companion 2.2.4:

  • Adjusted the NXT – Obstacle Course table to more closely meet the level specifications
  • Adjusted the VEX – Robo Slalom 2 table to give more room between the lines and obstacles
  • Adjusted the Camera 2 View of the VEX – Minefield Retrieval Challenge

What’s new in VEX Sack Attack 1.5.1:

  • Resolved a bug where motor values were being overwritten

What’s new in Ring It Up 1.5.1:

  • Resolved a bug where motor values were being overwritten
  • Adjusted robot models to drive straighter
  • Adjusted sensor and encoder behavior
  • Improved the gripper-ring interaction behavior

Thanks again for the feedback, and keep it coming. You can post it to the Robot Virtual Worlds section of the ROBOTC Forums.

FTC Ring It Up and VEX Sack Attack v1.50 Now Available!

with 2 comments

Following up from an earlier post, new versions of the FTC Ring It Up and VEX Sack Attack Virtual Worlds are now available!

In version 1.50 of Ring It Up, all arm, wrist, and gripper motors now include encoders, allowing you to get feedback and implement precise control over the robots. We’ve also swapped the Compass Sensor for the Gyroscope, which was highly requested by FTC teams. New Sample codeĀ  for the encoders and gyroscope is installed with the world.

 

In version 1.50 of Sack Attack, we’ve added encoders to the arm motors on all of the robots, and a potentiometer to the scooper motor on Scooperbot, giving you very precise control. All robot models have also had the Compass sensor replaced with a Gyroscope, better aligning them with the real world VEX system. As with the Ring It Up world, Sample code for all of the new functionality is included.

We genuinely appreciate all of the feedback and comments we’ve received about these worlds, and we hope that these changes show that we’re listening. Keep the feedback coming!

Adding support for all of the new inputs required a significant update of our back end, so these versions require ROBOTC 3.54 or later to be installed. Happy programming!

RVW Sneak Peek!

with one comment

We want to thank everyone who has been using our Robot Virtual World software and providing valuable feedback. Just so you know we’re listening, here are some of the major improvements that will be coming soon!

We had to do an overhaul of our infrastructure, but our VEX Sack Attack and FTC Ring it Up competition tables now support encoders on each joint! Here’s a screenshot of the Sensor and Motor Debug windows – look at all those inputs and outputs!

FTC Ring it Up!
Every NXT and TETRIX Motor on the robots is now equipped with an encoder. Due to several requests, we’ve also replaced the Compass Sensor with a Gyroscope! (Click the picture to enlarge)

VEX Sack Attack
Like the Ring it Up table, we’ve added encoders to the “shoulder” motors on Scooperbot and Clawbot. We also added a potentiometer to the scooper on Scooperbot, and Gyroscopes on all three of the robot models! (Click the picture to enlarge)

These are just some of the major improvements we’ve made in the competition tables. We’ve made lots of other great ones that you’ll just have to wait to see. :)

Keep an eye on our blog for their public availability, scheduled for the very beginning of November.

RVW Update: VEX Sack Attack v1.2.1 Now Available!

without comments

Attention all VEX teams! We just released a substantial update to this year’s VEX Sack Attack virtual world. Download it here, or on the RVW Level Packs download page. Here’s what’s new:

New Robot: Clawbot

  • Clawbot features a 4-wheel, 2-motor drive system, an arm motor, a gripper, and the full array of sensors. Best of all, it’s fully programmable in ROBOTC!
  • Additional sample code for Clawbot is installed with the update, and can be downloaded here.

Pre-loads and Automatic Scoring

  • Both Gripperbot and Scooperbot can be pre-loaded with a sack! You can control what side the robot starts on, whether it gets a pre-load, and enable the autonomous duration all from the main menu.
  • Scoring is fully implemented in this new version.
    • Earn normal points from sacks, bonus points from bonus sacks, and even more bonus points from the autonomous bonus and “parking” your robot before time runs out.
    • A cool, new timer and scoreboard keeps track of the match in the top-left corner of the window. Compete with your classmates or teammates to see who can get the highest score before time runs out!
  • Driver Control loads are also implemented once the autonomous period ends. Introduce them into the playing field by clicking on the green sack icons in the top-right corner.

Sensor View

  • Ever wonder why your Ultrasonic sensor “sees” the values that it does? Enable the new Sensor View to see what’s triggering the Ultrasonic sensor and the heading of your compass.

Additional Enhancements

  • We’ve improved the robot-sack interaction on all of the robots.
  • The lighting and contrast of the game have been enhanced, making it easier to grab and score the sacks.
  • Lots of small tweaks and adjustments.

VEX Sack Attack Referee Training Videos

without comments

John and Karthik at VEX Robotics have put together a fantastic set of videos for teams competing in the VEX Sack Attack Robotics Competition.

The 9-video series breaks down the rules for the competition, and shows how referees will interpret the different scenarios that may occur. It’s definitely a worthwhile watch for any teams competing this year (or anyone who wants to see John hug this years game object).

You can watch the full video series here, or on their YouTube page: http://www.youtube.com/playlist?list=PLEC832168771665F2
