A robotic system and method performs tasks autonomously on real-world objects (RWOs) upon receipt of inputs from a virtual reality environment. A robotic actuator has tools to manipulate the RWOs, and a set of robot-specific instructions for actuating the tools. A first set of rules governs the RWOs, and sensors detect the presence of the RWOs. A virtual reality (VR) computer uses sensor data to generate a virtual world (VW) including virtual world objects (VWOs) representative of RWOs. A second set of rules governs the VWOs. A user manipulates the VWOs to generate a modified virtual world (MVW). A transformation engine captures differences between the VW and MVW, transforms the differences into inputs for the robotic actuator. An autonomous instruction engine receives the inputs to identify RWOs and combines the inputs with the first set of rules to generate combined instructions usable by the robotic actuator to manipulate RWOs autonomously.
