Voice Controlled Lights using Raspberry Pi Voice controlled home application Today we are building a very useful project in which we can control the LED lights using our voice through Smart Phone. In this project, we will send voice commands from Smart Phone to Raspberry Pi using Bluetooth Module and Raspberry Pi will receive that transmitted signal wirelessly and will perform respective task over the hardware. We can replace the LEDs with the AC home appliances using relays and can build a Voice Controlled Home Automation Project. Components Used: ·          Raspberry Pi 3 (any model shall work) ·          Bluetooth Module HC-06 ·          Bread board ·          100 ohm Resistors (3) ·          LED’s (blue, red, green) ·       ...

Automated Portable Hammering Machine Hammering is the most widely used industrial as well as construction activity. Hammering or screws, metal sheets, parts etc requires a lot of time and effort. So here we propose an automated hammering system that allows for fully automatic hammering process. This allows for accurate, fast and automated hammering wherever and whenever needed using a 12V battery. The person just needs to insert workpeice and start the hammering machine. This machine can be used for automatic hammering work as and when needed. We here use a dc motor in order to move the hammer. The DC motor consists of a pulley attached to it which is connected to a larger pulley for efficient power transfer and to increase torque. This large pulley is connected to a shaft that has a connecting rod attached to it. This rod is used to achieve lateral motion from the spinning shaft. We now connect the other end of hammer to this connecting rod through a mid swinging arrangement i...

Robotics in Security and Military Applications Robotics have been a staple of advanced manufacturing for over half a century. As robots and their peripheral equipment become more sophisticated, reliable and miniaturized, these systems are increasingly being utilized for military and law enforcement purposes. “Military and battlefield applications continue to grow at an accelerated pace due to demand fueled by government investment. Over the past decade, we have seen increasing levels of investment in autonomous vehicles used for surveillance and security,” says Rush LaSelle, Vice President and General Manager with Adept Technology Inc. (Pleasanton, California) “Applications range from monitoring perimeters of secured areas such as airports to acting as a night watchman.” 1. Robots go to War Mobile robotics play an increasingly important role in military matters, from patrol to dealing with potential explosives. “With suitable sensors and cameras to perform different missio...
