The Software is designed and tested for use in simulations only. It may occasionally become unstable or otherwise behave unexpectedly. Therefore the Software does not meet the safety requirements for operating machinery, controlling devices that are capable of causing physical harm, or use in any other real-life situations. If the Software is incorporated in a system used in real-life situations, it is the user's responsibility to implement appropriate safety mechanisms, and ensure that a failure of the Software cannot cause physical harm or any other damage. LICENSORS SPECIFICALLY DISCLAIM ALL LIABILITY FOR DAMAGES RESULTING FROM USING THE SOFTWARE IN REAL-LIFE SITUATIONS.

Existing licenses

Existing MuJoCo licenses issued by Roboti LLC remain in effect until they expire. Users with paid licenses are eligible for technical support via email to todorov at roboti.us.

Personal licenses required computer-specific activation keys in the past. This is no longer necessary since we have now provided an unlocked activation key available to everyone. Users with Personal licenses may use the unlocked key on the terms of their existing license.
