Abstract: A conventional vehicle typically behaves like a single rigid body with fixed characteristics defined during the design phase of the vehicle. The rigid nature of the conventional vehicle limits their ability to adjust to different operating conditions, thus limiting usability and performance. To overcome these limitations, a reactive vehicle may be used that includes a sensor and a reactive system. The sensor may monitor the position and/or orientation of an operator, the vehicle operating conditions, and/or the environment conditions around the vehicle. The reactive system may adjust some aspect of the vehicle based on the data acquired by the sensor. For example, the reactive system may include a video-based mirror with a field of view that changes based on the operator's movement. In another example, the reactive system may include an articulated joint that changes the physical configuration the vehicle based on the operator's movement.
