JavaBot1……….. A line following robot

Design Goal:   The JavaBot1 is a small line following robot designed to follow a black line drawn on a dry erase board. It is designed to follow very tight curves. The software still has lot's of room for improvement but works well as is. Motive Power: The JavaBot1 uses 2 Cirrus CS-70 servos that have been modified for full rotation and have had their controller boards removed to convert them from serv ...

The Glowing Green Robot

Robots look cooler when they have a sinister green glow. Better yet, when that glow exists for a functional purpose it's even better! Here I show how to make a custom robot and use LED's to not only enhance line following, but also make it work in the dark too. Step 1: The Mechanical Design First you need to design your robot. I designed mine using CAD, planning out the locations of all the parts carefully. ...

The Rock

This robot is controlled by a visual basic program (through the serial port), and can move in three different velocities by a pulse width modulated (PWM) signal generated by a PIC microcontroller (16F877). The robot can be operated in two modes, "normal control" and "light tracker" modes. In the normal control mode, the robot can carry objects sized from 3 - 18 cm from place to another within 150 m. whereas ...

Cheap Easy Solar Powered Robot

Make a very cheap, relatively easy to construct robot which will wake up any time you shine a desk lamp on it. There are no sensors on it, although I suppose the solar panel can be called a sensor. I plan on adding solar panels and another motor, and making it controlled by a PIC microcontroller in the future. Step 1: The Circuit The circuit for the robot is very simple, it has no digital electronics. It's ...

Infrared Remote Controlled (RC) Steerable Vibrobot Created by Naghi Sotoudeh

Vibrobots (and bristlebots) are simple robots that use a tiny pager / cellphone vibrator motor (with an eccentric weight) to randomly bounce around -- they are the subject of many Maker / DIY projects as well as some well-known commercial toys (such as the $7.00 Hexbug Nano).  Naghi Sotoudeh, a Hizook reader from Iran, contacted us about his latest project: a remote controlled micro-scale vibrobot (measurin ...

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  ...
