DIY Muscle Sensor / EMG Circuit for a Microcontroller

Measuring muscle activation via electric potential, referred to as electromyography (EMG) , has traditionally been used for medical research and diagnosis of neuromuscular disorders. However, with the advent of ever shrinking yet more powerful microcontrollers and integrated circuits, EMG circuits and sensors have found their way into prosthetics, robotics and other control systems. Yet, EMG systems remain ...

Fire Fighting Robotic Vehicle

We all are well aware of the major fire accidents that frequently take place in nuclear power plants, petroleum refineries, gas tanks, chemical factories and other large scale industrial units and result in very serious consequences. Thousands of people have lost their lives due to such hazardous accidents. Therefore, the main objective of this project is to develop a robotic vehicle capable of fighting the ...

Interfacing LM35 Temperature Sensor with PIC Microcontroller.

The are many cool sensors available now a days, ranging from IR distance sensor modules, accelerometers, humidity sensors, temperature sensors and many many more(gas sensors, alcohol sensor, motion sensors, touch screens). Many of these are analog in nature. That means they give a voltage output that varies directly (and linearly) with the sensed quantity. For example in LM35 temperature sensor, the output ...

Digital Barometer using PIC Microcontroller and MPX4115A Pressure Sensor – XC8

The Motorola MPX4115A is an atmospheric pressure sensor powered by 5V and delivers and output from ~0.25V to ~4.75V based on the pressure detected at room temperature (25°C). The device provides a linear output based on pressure. As the pressure rises, the output voltage of the sensor rises as well with ~0.25V represents <15 kPa pressure relative to a vacuum and ~4.75V represents >115 kPa. Note that  ...

Fire Fighting Controlling Robots Used in Dangerous Situations

Robots can be used in many applications in industries, military, domestic. One of the major uses of Robots is an asset to human beings. Whether it is any kind of hazardous situations like a fire breaking out or a place full of landmines, Robots can easily work out a way out of these problems. So let us see these two types of Robots – A Land mine sensing Robot and a Fire Fighting Robot Land Mine Sensing Robo ...

IR Remote Controlled Tracked Robot

Step 1: Assembling the Double Gearbox A basic hobby motor turning at 12,300 RPM is basically useless without a good gearbox. Just touching the shaft will stall the motor. I obtained a Tamiya double gearbox kit for under $10, which through a series of gears provided a ratio of 114.7:1 at 115RPM. There were a lot of small parts in this kit; and it looks a little intimidating; but the pictorial instructions we ...

Line following Robotic Vehicle using Microcontroller

The project is designed to develop a robotic vehicle that follows a specific path. This project uses a microcontroller of 8051 family for its operation. A pair of photo sensors comprising IR transmitter and photo diode is interfaced to the controller to detect the specified path for its movement. Line follower robot is a useful robot that is used in ware houses, industries, and stores etc, where it follows ...

A Versatile PIC16F876A Based Robot

Design   Summary: Our group designed  and  manufactured a  miniature  robotic  vehicle  that  conquers  various terrains.    The  vehicle  was designed  with  a  track system  which is  powered  by  two  DC motors. The  motors   use a  Quadruple half  H ‐Driver in  order to  drive the  motors  in  both  directions.   The track system  incorporates a  four  bar linkage  for each  tread.    These two  linkage ...

Pingbot – Micro RC Rechargable Musical Robot Pal using PICAXE

Pingbot is a very small (38mm diameter), usb rechargeable, programmable, musical, remote control robot designed for maximum fun and danceability. I've built a few experimental robots in the past and, to be honest, they all looked the part. They were nothing more than circuit boards with wheels glued on.They did help me learn, but they just didn't feel like completed robots. The main purpose of this project ...
