Actor-Lab
From Wikipedia, the free encyclopedia
Actor-Lab is a program that visualizes the Lego Mindstorms RCX internal logic through visual flowcharts. The flowcharts are "Actors/Number Actors" which send messages to one another beginning, stopping, and ending. You can program within it and shows you what would happen if it was on the RCX, including simulation of motors, sensors, lights, and sounds. You can also add controls at the bottom of the screen to start, stop, or change the value of Number Actors. There is a similar program from Lego called Robolab. In Robolab, you can actually program to the Lego RCX.
[edit] Controls within
- Alt+Mouse Drag on an actor will move him to any location specified.
- Double Click on an actor will edit his current messages.
- Alt+Click on a control will edit the current actions that the control sends to actors.
Notice that there is one control that cannot be edited. This control is Power OFF or Stop.
