A few years ago I created 5 tutorials for the virtual robot experimentation platform (VREP). Robot simulation is a vital part of automation and VREP had a high barrier to entry. I created these tutorials for my students at the time to help them with their simulations. These are slightly outdated and some menu items have moved, but these do still serve a purpose.
The tutorials with the corresponding file downloads can all be found at http://edisondev.net/vrep
