FAQ: RoboBlockly
For questions about connecting and running hardware Linkbots using RoboBlockly, please see the "FAQ: Linkbot Labs and Linkbots" page and/or the "FAQ: Linkbot Troubleshooting" page. Connecting and running an Arduino board is covered on the "FAQ: Arduino and Robot Sensors" page.
How do I change the default download location when saving Blocks/Board/Grid or Ch programs in RoboBlockly?
What is the size of the background image (for the grid) that can be uploaded?
The size of the grid is 360 px by 360 px. The image that is drawn on the background can be any size, but if it is too small, the image will be stretched, and if it is too large, the image will be reduced.
Why does the grid on the background image not match the grid displayed in the uploaded blocks?
The grid in the background image may not match the grid in the uploaded blocks. For example, the background image may display the grid at 24×24 inches while the XML file that is loaded to display code blocks in the Workspace has the 36×36 inches option set.
I created multiple groups for students in my class in Class Management. After I assign homework for different groups, why cannot a student see a homework assignment?
Check that you assigned this student to a group and that you assigned homework to All Students.
What can I do if RoboBlockly is running slowly?
Turning on the sound on your computer may help. Also, having a lot of browser tabs open can slow things down.
The grid image (e.g., a RoboPlay Challenge Mat with the 96x96 grid) isn't being displayed properly. How can I fix this?
Clearing the browser's cache (where it stores copies of images, among other things, in order to enable faster loading of web pages) can help. For Chrome, see the instructions here. Instructions for a variety of browsers are covered here.
I can't seem to see all the code blocks in the menus. How can I get the missing ones back?
RoboBlockly has several settings to reduce the number of options and features displayed, in order to minimize distractions. For example, there is a "Simple View" checkbox below the grid area:
