In this paper, micro controller is used to control the thermal states of Flexinol wires which actuating legs of the insect-like legged robot. The design emphasizes mechanical simplicity as well as power and computational autonomy for lightweight walking robot applications. The kinematics workspace characteristics has been applied on to a test rig to examine and improve the motion feasibility wi...

Today, a highly integrated microcontroller can handle the functional control of these machines. To connect the microcontroller to the Internet, one must implement a protocol stack on the device. To function, this protocol usually requires a powerful processor, a complete operating system, and a large amount of memory. In this case, the implementation of a stand-alone Internet protocol stack cou...

Software simulators that emulate equivalent behavior of physical microcontrollers play an important role in the process of software development for embedded systems from an early development stage (e.g. when no target hardware is available) to the final verification process (e.g. used in combination with formal methods). Thus, much reliance is put on the correctness of these simulators. This pa...

A design of simple hardware circuit with different kind of fire sensors enables every user to use this wireless fire security system. The challenges in designing the nodes with various types of fire sensors are discussed and the methods to overcome design problems are also analyzed. The circuit is interfaced with the different types of sensor to sense different fire sources such as gas leakage,...
