vrep 3.2.0 for Mac is free to download from our application library. This software for Mac OS X is an intellectual property of com.coppeliarobotics. The software lies within Developer Tools, more precisely IDE.
From the developer:
The robot simulator V-REP, with integrated development environment, is based on a distributed control architecture: each object/model can be individually controlled via an embedded script, a plugin, a ROS node, a remote API client, or a custom solution. This makes V-REP very versatile and ideal for multi-robot applications.
