Computerized Controlled Robot (CCR)

Trial Version Description: CCR is two stepper motors following the exact motion of the computer’s mouse. The device is comprised of two main parts: An RF transmitter and an RF receiver. The transmitter, which is connected to the computer through the serial port, consists of a PIC microcontroller and an RF transmitter module. A Visual C++ program is loaded on the PC. This program opens a video window or an “avi” file. When the mouse scans this video file, motion is converted into an electrical signal which is sent to the transmitter, and then in turn to the receiver, which drives two stepper motors. Hence the mouse motion is converted into the vehicle motion, and so reproducing the exact mouse pathway.

Applications:

1. Automated cleaning.

2. Archeological exploration.

3. Astronautical exploration.

4. Guidance systems.

Options: Optional program which saves the mouse motion in a file so that it can be retrieved whenever it is required, to eliminate the need for manual mouse movement.

Electrical design , software and Implementation by: Mona Aly Elwy
Mechanical design and Implementation by: Hany George Nasr

Simpler explanation:
You take a photo or a video of the place you want to clean,you upload this photo or video into your computer & just move your computer's mouse on this photo.That's it, the Robot does the rest,it cleans this place that you traced with the mouse.

Multi-Purpose Circuit
Guess , What could be this circuit ???????????????
I made this circuit a very long time ago & I forgot completely about it, & while I was searching for something in my drawer, I found it & decided to publish it although it is very very primitive & simple.
The reason of this decision is that this circuit is multi-purpose.
It can be used to open & close Curtains (pls.visit http://www.forestgroup.nl/products/FMS.html)of course this is not my product but mine is very similar but not with a Remote Control,it has an individual switch for each curtain.
If you need to Relax on a beach ,it can be connected to your Chaise_Longue to move it however you want ,
also it is very useful in Hospitals to lift & move the patient's bed.
I'am sure that you can find many other similar applications.

Temperature Controller

It has been proved that animals are best feeded in a certain range of temperature.If this temperature gets higher or lower,their production decreases.That's why I made this device which is composed of a temperature sensor & a PIC microcontroller.

The device is adjusted at a certain range of temperature.If it decreases, the PIC automatically connects to a heater to raise this temperature to the required range.The same,if the temperature increases,the PIC automatically connects to a cooler to lower the temperature to the required range.
The Display shown in the figure displays an L if the temperature is Low (below the required range),an H if it is High (above the required range) or an A (Average) if it is within the required range

Image Detection

My project is formed of 2 parts:
1) Hardware: It drives a Stepper Motor to which a WebCam is connected. The whole device is connected to the parallel port of PC
2) Software : A visual C++ program works as follows:
a) When you press the driver button a window is opened & shows a video image of the Camera
b) When you Press Capture1,Bitmap1,ShowBitmap1 ,successively an image is captured & is shown on a window opened at the top left corner
c) Move your camera to any place you want
d) Press Start Time button, the camera driven by the Stepper Motor will move automatically until it reaches the same place of the captured image, then it will stop
3) Step 4:
Finally the aim of this project is to capture an image and to let a Stepper Motor detect the place of this image.

JEOPARDY

Do you know what's Jeopardy?
When I was first asked to make a Jeopardy device I had no idea about this game.
Then I kept searching in the Net until I got a full idea & started to design it's circuit.
Again , it's not my idea but the design is mine.
What's Jeopardy ????
Jeopardy ! is a game , covering topics such as history, literature, pop culture, and science.
During the game, a number of competing contestants are asked different questions & the contestant who would attempt to buzz in before the others is the winner.

Clap ON ! Clap OFF !
The Sound Activated ON/OFF Switch

The Clapper

If you can’t stand anymore getting out of bed to turn off the television because you lost the remote control….if you want to turn on the lamp in the middle of the night to drink some water and you don’t want to walk into the dark to find the switch…just clap and your problems are over!

The Clapper is a device that is activated by sound sensory,and will turn On and OFF any appliances plugged into it.
Do you come home sometimes too tired to even attempt to find the light switch?
Sometimes do you wish you didn’t have to get up from the couch to find the remote of the TV? The Clapper does the rescue!
The Clapper can also help physically handicapped people .By Clapping,it may give ON/OFF light or Ring a bell....,indicating the need for assistance .
Dimensions: 9 cm x 13 cm x 4 cm

N.B: I've got many comments accusing me of steeling the idea of this device.
I never said it's my own idea because it already exists but the design of the circuit of the clapper posted in my blog is my own design & no one in the whole world can ever deny this.
