Tahoe-II Development Board

Finnaly i got Tahoe-II Development Board today, thanks to my boss
Dr. Ahmed Javad, who has alway encouraged me to
welcome the new technology. Next couple of weekends will be very
interesting working on it.

The Tahoe-II development platform is the ideal place to start when developing small, smart, connected devices. Featuring the .NET Micro Framework, you have the hardware and software tools to get your project done faster than ever before.   Through its fully integrated Visual Studio experience, the .NET Micro Framework brings a reliable and productive development environment to the world of embedded development. Complex applications can be developed and debugged faster by leveraging the powerful emulator and Visual Studio’s debugging capabilities. The familiar development environment also enables .NET  desktop programmers to work easily on embedded projects. The Tahoe- features a 3.5” touch-screen LCD, wired and wireless networking, USB function for interfacing to PCs, an accelerometer for innovative sensing and user interface applications. When you need to prototype a new device, the Tahoe-II has easy access to an array of expansion options; including serial ports, I2C, SPI and plenty of GPIO.    The Tahoe-II is built around the Meridian CPU, while features a Freescale i.MXS ARM9 processor, 4Mbytes of Flash, 8Mbytes of RAM. Moving from prototype to production is simple with the Meridian CPU. The Meridian CPU and the .NET Micro Framework are ideal for applications such as; industrial automation, home automation, healthcare, consumer devices, retail point-of-sale, PC peripherals, and automotive applications.

Specifiaction of Tahoe-II

• Meridian CPU (ARM920 @ 100MHz, 4Mbytes Flash, 8Mbytes SDRAM)
• 3.5” Landscape TFT LCD with touch-screen
• 9 user input buttons
• RS232 serial (DB9)
• USB Function
• Ethernet
• Accelerometer, with support for event notification including free-fall detection
• SD Card interface
• Temperature sensor and 2x ADC channels
• Interface for XBee wireless module (and additional ADC channels if fitted)
• PWM output
• Expansion connectors that expose GPIO, I2C, SPI and UART signals

The Tahoe-II supports version 3.0 of the .NET Micro Framework.  A Board Support Package (BSP) for use with the Porting Kit is under develpment for advanced users.

Meccano Spykee Wi-Fi Spy Robot

I heard of this robot few month earlier and it really attracted me.

You all know about good feature of skype and if those are plugged into robot you can imagine how 

interesting it would be. Many people have Wi-Fi network at home now a days, and this robot is connected to Internet using your home or office Wi-Fi, you can remotely operate this robot via internet and talk to you your family, kids especially.

The Spykee Robot is spy robot kit that stands at approximately 1 foot tall. 

Once built, this remarkable robot acts as your walking, talking spy, a wireless VOIP phone, 

a webcam, a digital music player for your MP3s, and personal video surveillance thanks 

to Spyke's motion detector. The Spykee comes with 210 parts and is compatible

 with other 

Meccano sets for customization.

Characteristics:

• Spy robot - Spyke moves, watches, speaks and listens 

• VOIP phone - Use your Spyke as a wireless VOIP phone (compatible with Skype 3.0 PC technology) 

• Digital Music Player - listen to your own music over Wi-Fi with Spyke 

• Video Surveillance - When a movement is detected, Spyke activates an alarm on your computer or sends you a picture by email

• Other play functions include snapshot, sound and video recording, light, voice and sound effects and video filters 

• Wi-Fi card included 

• Motion sensors activate automatically when something happens 

• Returns to recharging station automatically when battery is low 

• Control on local Wi-Fi connection or remotely via internet 

Run the comprehensive software and you have a Wi-Fi enabled robot that can be controlled on a 

local connection or remotely from the Internet on a well-crafted and easy-to-navigate MMI or 

Machine Man Interface. This page can be opened using the CD ROM provided.

See how it looks like before you purchase.

Need Robot Parts

There are lot of online stores from where you can get the robot parts but i really like the www.robotshop.ca for this purpose, they support variouse payment methods including money order and wire transfer. you can also use paypal. Following are some caretories fromar robotshop.ca.

iRobot Roomba Parts Microcontrollers Sensors Motor Controllers Motors and Actuators Communication and Control Power Systems Software LCD and Display Interface Adapters and Converters Cables, Wires and Connectors Components

There are also lot of sotres in UK but if you live in Ireland, you can 

get some electronic items from Peats and Maplin, 

but they dont have a wide range of robotic items. so you many need to order online.

Boe-Bot Robot with Bluetooth

There are 3 types of Boe-Bot avilable with USB, Serial and Blue tooth version. But blue tooth version is realy rocking one. This Boe-Bot robot is paired with the eb500 Bluetooth  Transceiver AppMod, a

 winning  hardware combination to use with your PC as a base station. When used in conjunction with other PC programming environments,  tremendous opportunities exist for large-vo

lume datalogging, remote operation, web monitoring, real-time data analysis, and more. The choice is yours!

Sensors to make your Robot more intelligent
Boe-Bot come with all necessary items you require to built a bot. Additionally you can get sensors to have more experimeno ts.

2. CH4 Gas Sensor Module
3. Digital Thermometer
4. Flexiforce Sensor Kit
5. Tri-Axis Accelerometer
6. Compass Module

Crawler Kit
You can make your Boe-Bot Robot a Crawler by adding Boe-Bot Crawler kit, which can be additionaly purchased. The Crawler runs on standard Boe-Bot source code with only minor adjustments for ground speed. Sample PBASIC code is included in the documentation.

Gripper Kit You can covert your Boe-Bot Robot in a lifter by Gripper Kit. Gripper Kit adds pick-up and carry capability to your Boe-Bot Robot. The Gripper features parallel plates that open, clamp onto and lift objects all with one cleverly utilized Parallax Standard Servo. Since the Gripper's servo plugs right into a servo port on the Board of Education, no additional battery pack is needed. The lightweight but sturdy aluminum, brass and plastic Gripper hardware weighs less than 7 ounces. Sample Programme of Boe-Bot... This program will prompt you for the number of pulses to send to the servos, and then the pulse width to transmit to each servo.  The program sends about 43 pulses per second, so 43 pulses would give you 1 second of run time, 86 would give you 2 seconds, and so on.  For speed control, 800 is about full speed counterclockwise, 700 is full speed clockwise, and 750 is stop.  If you want a wheel to go half speed counter clockwise, try about 775.  Half speed clockwise, would be about 725, and so on.

RFID (Radio Frequency Identification)

RFID has become very popular now a days, it being used as auto data collection (ADC) technology in many fiel

ds for example Passports, Libraries, School, Universities, Hospitals, Stores and Museums.

RFID is way of tracking objects using the radio waves typically called an RFID tag. Some tags can be read from several meters away and beyond the line of sight of the reader.

There are two major parts, One is an integrated circuit for storing and processing information, modulating and demodulating aradio-frequency (RF) signal, and other specialized functions.The second is an antenna for receiving and transmitting the signal.

On the other hand some say that using this technology for identification is a security threat, for example countries that put RFID in passports include Norway, Japan, most EU countries including Ireland and UK, Australia and the United States, Serbia, Republic of Korea.
