Most owners of Android smartphones use them exclusively for communicating with other people. However, today the phone has much wider functional – not just phone calls and various Internet services. Few people know that they can use their smartphones as a remote control for the computer, TV or robotic mechanism. For example, you can connect a toy robot with the NXT controller to Android via Bluetooth and control it. In this article, we will talk about these and other features.

Robots with the NXT chips

Nowadays, any schoolchild can assemble a remotely controlled toy robot using the Lego Mindstorms constructor. Military designers took part in developing the concept of this toy. Such a robot is able to solve adult problems.

NXT controller acts as the brain of such robots. It consists of two microprocessors, Bluetooth module, LCD display, speaker, battery, various sensors and servo drives.

Thanks to the built-in wireless module, the user can control such devices from his Android phone. There is special software for this purpose.

There are several applications for remote control and they were created by different developers. They all have roughly the same number of functions and differ mainly in the interface. We will provide a few links to such applications.
