Abstract: A solar-powered device that moves advertising signs to attract attention of passersby is disclosed. The Solar panels makes the solar sign spinner independent of the electrical grid. It moves from a power source that is free. This gives it the freedom to be used in remote locations. The lack of dependency on the power grid makes the device easy to transport to remote locations. The solar sign spinner can operate as long as there is sunshine. If it happens to stop motion due lack of sunlight, it becomes a garden variety “yard” sign.

Abstract: A control system that guides a robot or articulated device with a laser distance meter for 3D motion, or guides a robot or articulated device with a computer pointing device (such as a mouse) for 2D or 3D motion. User needs to point to a desired physical location of the end point, and then the difficult work of finding the right joint angles to get there is done by a computer. System works like hand eye coordination. The hand goes wherever the eye is pointed so long as the eye is pointed within the reachable boundary of the jointed arm or articulated device.
