1 The Robot control using the wireless communication and the serial communication

Build an RC Plane Finder

The lost plane finder introduced here is a little on board beacon, also known as lost model alarm/crashed aircraft beacon, which helps you find a crashed or downed radio-controlled plane. The concept is to get an alert from a piezo sounder if there are no signals from the associated radio-controlled transmitter. Usually, the radio transmitter provides a set of pulses every 20 milliseconds, which, in turn, sends the radio receiver a separate pulse to each of the servos at the same interval. In this circuit, an alarm will sound when the radio receiver no longer receives the set of pulses from the radio transmitter. Fig. 1: A typical lost plane finder To locate the aircraft, all you have to do is switch your transmitter off and the system will start to beep. The circuit is very easy to build and does not require any special parts like costly microcontrollers. A typical lost plane finder is shown in Fig. 1.

CELLPHONE OPERATED ROBOT

Conventionally, wireless-controlled robots use RF circuits,which have the drawbacks of limited working range, limited frequency range and limited control. Use of a mobile phone for robotic control can overcome these limitations. It provides the advantages of robust control, working range as large as the coverage area of the service provider, no interference with other controllers and up to twelve controls. Although the appearance and capabilities of robots vary vastly, all robots share the features of a mechanical, movable structure under some form of control. The control of robot involves three distinct phases: preception, processing and action. Generally, the preceptors are sensors mounted on the robot, processing is done by the on-board microcontroller or processor, and the task (action) is performed using motors or with some other actuators. Project overview In this project, the robot is controlled by a mobile phone that makes a call to the mobile phon...

Introduction To Smart Wi-Fi

We need faster tools and media to prove our ideas, and this is where ready-to use modules like Smart Wi-Fi enter. Fig. 1 shows the top side of Smart Wi-Fi module. Fig. 1: Smart Wi-Fi module Fig. 2: Block diagram of the introduction of Smart Wi-Fi The module is low-cost and versatile; all a developer needs is a USB cable and it is ready to work. For software developers, working with hardware is always a pain, and this is one of the biggest reasons why many ideas never exit a computer. Smart Wi-Fi enables making a product quickly and reliably. With open software resources and hardware data, moving to the final product after the proof of concept is also easy. One of the major aims for writing this article is to show the versatility of this product and show how quick the development can be. In this article a few tests with Smart Wi-Fi are discussed, which show the applicability of this module for development of the Internet of Things (IoT) products. Fig. 3: C...
