Understanding the Grasshopper Script

The Grasshopper script allows you to program the Robot and convert geometry from Rhino into toolpath geometry. Step through the following guide in order to program the Robot correctly.

Functions of the Script

The script has been colour coded to categorise the function of each component with the overall process.

Name your file

Keep your naming convention simple. Avoid any special characters or long names, as this file name is what will be visible in the Robot interface. Start your name with a letter to avoid a Robot error. For example: Nigel_test_01.

Robot Parameters - Connecting to the Robot

Ensure you have connected to the Unimelb - IRB1200 for the Large Extruder. Alternatively, if you are using the Small Extruder you will need to connect to the Unimelb - IRB120.

Converting objects to toolpath geometry

Depending on the type of geometry, the script requires an input of either a series of curves or a solid geometry which it will translate into toolpaths.

If you have a series of multiple polylines or curves which make up your geometry, you will need to select your curves in sequential order of printing before you [right-click] and select [Crv]. The script

Print preview: Using the functions in the Simulation and Print panel, slide the simulation bar in the script to ensure the robot toolpaths have been generated correctly.
