Spy robots are remotely controlled robots, equipped with a camera, transmitting video data to the remote area. A movable spy robot with a remote controller by using raspberry pi. The spy robot is made up of a USB camera, Wi-Fi adaptor, batteries and movable wheels. To remotely control wireless system and to control Spy robot Wi-Fi technology is used.

Remote Operated Spy Robot is a small robot designed for spying, surveillances and inspection purposes through web browsers from any corner of the world.

The components of solar powered intelligent drip irrigation system are shown in Fig. Soil moisture sensor is used for real-time collection of crop root soil moisture content and converting it into a signal in the range of Voltage V; and the signal will transformed as knowledge of water requirement of crop. Soil moisture content at the root zone of different crops is collected by using the soil moisture sensor. The threshold limit for the water requirement for a particular crop has been feed to system which in turn controls the operation the control system. The power needed for the operation of the control system has been met with the use of a solar panel and the display will receive the control signal and display the data stored using the sensor from the field.

Indoor navigation is convenient for everyone, and it is especially indispensable for the visually impaired. We proposed such a navigation system for the visually impaired .LED lights emit visible light with location data and a embedded system or smartphone with a visible light receiver receives the data. The embedded system or smartphone calculates the optimal path to a designation and speaks to the visually impaired through a headphone.
