We decided to design and build a robot capable of vacuuming the floor of a room or area without any human interaction other than just starting the unit. We realized the need for a cheap and convenient product that can be easily used to vacuum a room on its.... -
After testing the motors I found current draw as high as 1. 3Amps. So I stuck 2 of the SN754410 H-Bridges on top of each other, and then built a heat sink from an aluminum can. Should be OK for 2Amps or more. The heat sink is just the aluminum can bent into.... -
This circuit controls the switching of the street light or porch light and it will be automated. This circuit of automatic lamp controller using 7806 regulator IC can be used to automate street lights, tube lights or any other house electrical lightning.... -
The stoboscope tube needs about 250-400V DC to operate. This aerial voltage is generated application simple voltage footfall up ambit congenital from transistors Q1, Q2 and agent T1. This ambit gives out about 230V AC voltage which is again rectified with.... -
Large Dancing Robot Build a large dancing robot. This was supposed to be a walking robot, but it more kinda beebopped around. video on last step. Build a P.... -
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 c.... -
RF is just way too cool not to use in your designs. But if you`re a newbie like me it is difficult to successfully build solid RF transmitters and receiver.... -
The Tiny Remoteis a very compact infrared remote control with only two buttons to control an iRobot Roomba. It produces three different infrare.... -
K`nexapod is a hexapod robot built with K`nex building toys and controlled by a PICAXE microntroller. Propelled by small hobby servos it can move forward, backward, and make turns. It is equipped with an ultrasonic sensor and follows a simple algorithm to.... -
To get a good voltage swing, the value of R1 must be carefully chosen. If Rsensor = a when no light falls on it and Rsensor = b when light falls on it. The difference in the two potentials is: in presence of light and a very large resistance in absence of.... -
The headlights and photo cells will face the ground, so I find it easiest to imagine that the whole circuit is upside down Why 3 LEDs per side As far as I can tell, because you can`t power three in series from a single 9V battery without a little help, and.... -
Mostly everything has been put together for the electrical portion of the project. Serial communication is almost working and will be used in conjunction with a Teensy 2. 0 chip to communicate through serial USB and the mega128. A TTL UART serial driver such.... -
I hacked together a quick and dirty Arduino MIDI-to-DMX control for our robot band Science Fiction Children. It`s really simple! And here`s how I did it. I have two really cheap LED Par56 from Stairville (DMX controlled), a simple DMX-Dimmer pack and use.... -
A prototype model of Agriculture Based Robot . Till recently the farmers were using age-old instruments in cultivating their lands. They themselves were putting the manuallabor. Hence there was thelabor problem. Farmer`s facing this type oflaborshortage..... -
This page contains circuit diagrams and code for a walking robot I made using Mark Tilden`s nervous network along with my own tinkerings like the reverser and brain circuits. Construction is a bit odd, chips with pins bent flat with wirebits and parts.... -
A hexapod walker robot that uses three servos. It uses a Parallax Basic Stamp I for its brains, and let me tell you, its all this controller can do just to make the bug walk! Walking is MUCH more complex than just rolling! I will have more details and pics.... -
I decided to build an infra-red object detection system using High Output IR LEDs. For the controller of the robot I used the Parallax BASIC Stamp I. The latest greatest version of the software, at least as of 10/9/98, gives IRBOT three modes of operation..... -
A model boat that can sail autonomously along a course planned in advance. This explains the meaning of "Roboat" that is the short form for "robot boat". The core is the controller M68HC908GP20 (the quad flat plastic pack version) that stores the coordinates.... -
This Line Following Robot sensor or surface scanner for robots is a very simple, stamp-sized, short range (5-10mm) Infrared proximity detector wired around a standard reflective opto-sensor CNY70(IC1). In some disciplines, a line following robot or an.... -
It is based on the Miller solar engine and has no digital electronics involved. But before we get started, it must be said that a robot is defined as "a mechanical intelligent agent which can perform tasks on its own". Note that the definition does not state.... -
Constructing a robot or should i say a vehicle dat uses 2 motors. I managed to get sum referance regarding d schematics for the circuit design but the current schematics uses a smaller motor. which draws less power and uses a much less power supply. the.... -
This project was completed during a course on robotics taught by Prof. Dave Barret at Olin College. The final project for the course, the goal of the project was to navigate a maze using a Surveyor robotic platform. As part of this project, additional....

This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is.... -
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to.... -
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This.... -
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the.... -
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
