1. Soccer Robot
This soccer robot can move forward, reverse, forward-left, forward-right, reverse-left and reverse-right with the help of an Android phone. The speed of its movement is controlled by the angle of rotation of the phone. The robot also kicks a ball when the phone is shaken. Click here to read the full article.
2. Smart Solar Charger
Here we present the circuit of a highly efficient, automatic solar charger based on PIC16F877A microcontroller. It shows the system status on an LCD and can trickle charge. Click here to read the full article.
3. Wireless Gesture-Controlled Robot
In this project we are going to control a robot wirelessly using hand gestures. This is an easy, user-friendly way to interact with robotic systems and robots. An accelerometer is used to detect the tilting position of your hand, and a microcontroller gets different analogue values and generates command signals to control the robot. This concept can be implemented in a robotic arm used for welding or handling hazardous materials, such as in nuclear plants. Click here to read the full article.
4. XBee-Controlled Aircraft
This is a remote-controlled aircraft project based on Arduino and XBee modules. The aircraft’s movement is controlled through a brushless DC motor and three servo motors. It has an XBee-based remote control at the transmitter end and an Arduino-based aircraft at the receiver end. The aim of this project is to develop a 4-channel wireless remote control (RC) system with one XBee each in transmitter and receiver. Click here to read the full article.
5. Transformerless Power Supply: A Cost-effective Power Solution
If a circuit requires very low current of a few milliamperes, transformerless power supply is an ideal solution. Here is a guide to designing your own transformerless power supply. Click here to read the full article.
