BeagleBot - Beagle powered robot

"For measuring distances I chose to use SRF08. It is an ultrasonic ranger with I2C bus and measure range from 3 cm to 6 m. The sensor has a beam width of 55 degrees (-6 dB points) and when mounted on top of one of the servos it can be used for covering well over 180 degrees."

BeagleBot - Beagle powered robot - A small experimental robot with Beagle Board as it's heart.

Servo System -Double Hitec HS-422 servos mounted on a special two axis brackets. - 5 pcs of normal RC servos with 50 Hz PWM control. ATMega16 at the expansion board creates the PWM for all of the servos and provides an I2C control interface for them. User space application running on beagle board can thus control the servos just sending only a simple I2C message.

GloLab - Electronic Kits and Modules

GloLab - Electronic Kits and Modules

Digital Infrared Motion Detector Module

Miniature micropower motion detector module uses a digital pyroelectric infrared sensor to detect a moving human or animal, operates on 4 to 15 volts and can directly drive a LED or relay. This module can be used with a FL40 or FL65 Fresnel lens or other types of lens.

A Glolab KIT consists of a PC board and parts that must be mounted on the board and soldered in place by a user. A manual with assembly instructions, schematic diagram and physical layout diagram is included with a kit. Other user supplied parts may be required in order for a kit to perform a specific function after it is assembled.

Basic Four Channel Wireless Transmitter and Receiver

These basic kits include the components needed to build a functioning wireless remote control system with only the addition of power sources and some wires. 

Basic Four Channel Wireless Transmitter and Receiver
The kits uses RF transmitter and  receiver circuits that operate at 418 MHz with a range of up to 1000 feet. Thanks to these new modules  the problems associated with building your own transmitter and receiver such as tuning by adjusting capacitors and inductors are things of the past.
