More great news for Robot Virtual World users! Operation Reset version 1.5.2 is available and includes some fixes and great new features. The most notable of the new features is what we’re calling the Measurement Toolkit.
Research conducted with the Robot Virtual Worlds (RVW) has shown that it is actually a more efficient tool for teaching how to program than real robots. RVW allows you to learn how to program with motors and sensors, but without the wasted time of charging batteries, resetting the robot, repairing damaged parts, and so on. That said, one limitation of the Virtual Worlds has been that you couldn’t just place a tape measure and protractor in the world like you could with a real robot… until now. The Measurement Toolkit takes all of the guess-and-checking out of using the Virtual Worlds, and more importantly, allows them to be used as extremely valuable tools for teaching and reinforcing crucial math concepts like proportionality.
The Measurement Toolkit consists of 3 new buttons, placed along the right side of the Operation Reset interface:
- SHOW The SHOW button turns the Measurement Toolkit on or off. When turned on, it will display the distance and angle to “key objects” in range of the robot. For Operation Reset, this means objects like the Charge Cubes (see below), Fuel Barrels and Crystals. Turning the Measurement Toolkit on also creates a line coming out of the robot that shows its heading (the red line below), and enables you to ADD your own “key point markers” in the world.
- ADD The ADD button lets you to place your own “key point markers” (see below) in the world, allowing you to find key distances and angles for your robot to traverse. Once the Measurement Toolkit is turned on, you must also click the ADD button to enable it. Once you do, simply click on the spot in the world where you would like a marker to be created and one will appear, along with the distance and angle from the robot (see below). Up to three sequential markers can be created by clicking on multiple spots in the world, allowing you to do some intelligent path planning. When your robot drives into one of the key point markers it is removed, and the next key point updates to show it’s distance and angle directly from the robot. If you’re unhappy with any of the points that you create, you can right-click with your mouse, and the last point you created will be removed.
- CLEAR The CLEAR button removes all of the markers that you’ve created in the world. It is only enabled if you have created your own key point markers.
The Measurement Toolkit will change how you use Robot Virtual Worlds and enable new possibilities whether you’re using them in the classroom, for fun at home, or to help prepare for a robotics competition. We’ve already included it in Palm Island: Luau Edition, and will be updating our existing worlds to include it. We’re also producing some video materials that show step-by-step how to use the new functionality, so be on the lookout for those in the coming weeks.
As always, we appreciate any feedback you have about the Robot Virtual Worlds, Operation Reset, and the Measurement Toolkit. Please share it on our Facebook page, here on the blog, or the ROBOTC.net forums.
