Abstract

In our introductory VoxCAD project, we provided you with a template file that included default material properties and physics simulation settings. These settings include friction, gravity, and temperature — all of which can drastically change how fast your robots move. However, we did not explain what exactly all these physics simulation settings meant, or how to change them. You can access the physics settings through the Physics Settings tab after entering the Physics Sandbox mode, as shown in Figure 1:

Screenshot of the physics sandbox in program VoxCAD shows a menu where a physics settings tab can be selected on the bottom-right of the program window. The physics sandbox can be toggled by selecting a small icon on the top toolbar that resembles two blocks next to each other. A large viewer is present on the left side of the program and multiple sidebars line the right side of the program. These sidebars include voxel information, options to change physics settings, and display or view options for the viewer.


Figure 1. Access the Physics Settings tab in Physics Sandbox mode, which you enter by clicking the Physics Sandbox button in the toolbox at the top of the screen.

We highly recommend watching this video tutorial as an introduction to the different physics settings:

Video of VoxCAD Physics simulation mode
Watch this video of VoxCAD tutorial on the physics simulation mode. This video contains some engineering terms such as strain, inelastic, and actuation. You do not need to know what these terms mean to do this project, but you can look them up if you are curious. Note that this video was made using an older version of VoxCAD, so the location of some of the settings in the Physics Settings tab has changed.

For reference, we have listed the available settings here. Note that you can also hover your mouse cursor over the text describing each setting in the VoxCAD window to read a description. Note: this page was created in July 2013 using VoxCAD version 0.9.9. Future versions of VoxCAD may add or remove options, or change the exact locations of different buttons in the program. The general concept should remain the same, so this page should still serve as a good introduction to the physics settings.

These are always available toward the top of the Physics Settings tab:

These settings are available under the Environment sub-tab:

These settings are available under the Other sub-tab:

Remember, this is an abbreviated project idea, so exactly what you do next is up to you. Here are a few suggestions:

Career Profile
Have you watched "The Transformers" cartoon series or seen the "Transformers" movies? Both shows are about how good and evil robots fight each other and the humans who get in the middle. Many TV shows and movies show robots and humans interacting with each other. While this is, at present, fantasy, in real life robots play a helpful role. Robots do jobs that can be dangerous for humans. For example, some robots defuse landmines in war-stricken countries; others work in harsh environments like… Read more
Career Profile
Robots are no longer futuristic machines. Robots are here and now and are used in manufacturing, health care, service industries, and military applications. They perform tasks that are repetitive and hazardous—things that humans don't want to do or are unsafe to do. But robots are still machines, which means they require humans to build, maintain, program, and keep them functioning efficiently. Robotics technicians work with robotics engineers to build and test robots. They are… Read more
