To control the robot’s motors need a device that would have transformed the control signals of low power in the currents that are sufficient to control the motors. Such a device called the motor driver .
There are many various schemes for motor control. They differ in how capacity and element basis on which they are made. We will focus on the simplest driver motor control, performed in a completely ready for operation in the chip. This chip is called the L293D is one of the most popular chips intended for this purpose.
L293D contains just two drivers to control the motors of low power (four independent channels, combined in two pairs). It has two sets of inputs for control signals and two pairs of outputs for connecting electric motors. In addition, the L293D has two entrances to the inclusion of each of the drivers. These inputs are used to control the speed of electric motors using pulse width modulated signal (PWM).

Creating BEAM-robots – it’s not just the manufacturing process or a fascinating hobby. BEAM – an entire culture, with its philosophy, aesthetics, and a tremendous level of creativity. There are people who think BEAM-bots are not just a cult phenomenon, but a kind of religion. This is partly true. Although, if you talk about in terms of BEAM robotics, we can all be argued that the idea of BEAM is a new technological paradigm and philosophy in modern robotics.
