For some of these simulators you can download them (which is the best way to use them), others use Unity. If in google chrome you just get a black screen, try internet explorer.

If you know of any other links to simulators please reply or message me so I can add it to this list. Also, please don't link the "Forklift Simulator" game. My personal favorite (so far) is the one on xantaz.netne.net because there are two robots, one for stacking and one for putting bins on top so you can have two players and work together. As well as that it has a timer and has a live score of the game. And uh, not to brag, but I got 5 stacks of six *flexes*
