This circuit was developed for the needs of the robotic arm PidiArm, precisely control its servos modeler. The reason for developing self-governance was that commercially available circuits are usually not able to make a smooth move by themselves and must be implemented in ways that are sensitive to speed communication with the superior circuit. But Servo7QG is solution of this and some other problems, so it could be operated via relatively slow I²C bus.

Another of my projects was my bachelor work too. It's consist of small robotic arm PidiArm and own production conveyor belt. It can sort tops of plastic bottles by color and it is possible to control the sorting line model via a PC. The practical outcomes of this work are RGB sensor, distance sensor and control unit for servos whitch will be described in a separate article.

This chapter describes the design of a simple development kit. With its help will be easy to test all the peripherals of the QG. I have tried to design it in the way which will make possible to connect another extension boards or other development kits for the need of test of communication peripherals, etc.
