A teleoperated robotic system that includes master control arms, slave arms, and a mobile platform. In use, a user manipulates the master control arms to control movement of the slave arms. The teleoperated robotic system can include two master control arms and two slave arms. The master control arms and the slave arms can be mounted on the platform. The platform can provide support for the master control arms and for a teleoperator, or user, of the robotic system. Thus, a mobile platform can allow the robotic system to be moved from place to place to locate the slave arms in a position for use. Additionally, the user can be positioned on the platform, such that the user can see and hear, directly, the slave arms and the workspace in which the slave arms operate.
