Low-cost embedded intelligent system design for smart mobile robot controller

The motion and sensing controllers are the main parts of any intelligent mobile robot. This paper has studied and tested the minimum possible hardware-consuming cost of motion and sensing controllers for mobile robot applications. The VHDL (Very high-speed integrated circuit Hardware Description Language) is used to design a counter-based architecture of motion and sensing controllers to gain the lowest possible implementation cost. Then a deep study of the designed architectures proved that it produces an economical use of hardware resources when implemented in XC3S1000 FPGA (Field Programmable Gate Array) device using ISE 14.1. The designed controllers worked successfully after implementation in XC3S1000 with 34 Slices cost only.
