This time we will try to create a robotic platform for crawlers. Materials that we will use this time is PVC foam – sheets. This white plastic, sheet-shaped solid with the texture of the matt / doves on both surfaces. This material is very easy to cut, sawn, or drill.

Designed for small wheeled robots, the driver is ideal for robotic classes Mini-bag, following the lineand the labyrinth of disciplines. The driver is based on the chip L293D. For the driver, you can connect two motors. The driver can operate in two modes: Mode A – always served drove a high level and, therefore, engines will be spinning at maximum speed mode with a ringing in the pulse-width modulation (PWM), supplied with the controller, you can change the motor speed.

On the Internet there are many examples of code for AVR-GCC , written using functions and macros that are no longer supported in newer versions of the compiler. To use these examples and understand them with the essence of the ports of the microcontroller, you need to rewrite code or use special macros.

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).
