Cheap1 - A very cheap robot built as an experiment to see if we wanted to do a robot class for high schoolers or beginners (and to learn more about parallel port stuff). Pictures, AVis and a short description __ Designed by DC Reagan
Chloroplast Voltage Controlled Solar Engine - Voltage-Controlled Solar Engine: These designs are based on the Motorola MC34164-* micro power undervoltage sensing IC s. They're pretty efficient, work at higher voltages than most solar engines, and can provide voltages for other logic circuits (say, a microprocessor). This page hosts the original Chloroplast by Craig Maynard, as well as some Chloroplast variants by Wilf Rigter. __ Designed by Craig Maynard
Church Bell Controller - This circuit is a church bell controller. Basic component is an ATmega32 microcontroller. At the circuit 2 24LC32 eeprom memories is being used, the 1st for internal standard melodies and the 2nd one is for user's compositions. This feature will be provided in the future __ Designed by Antonis Pontikakis
Code Provides Adjustable Differential Drive for Robots - 10/16/03 EDN Design Ideas: intelligently modifying the motor-drive commands to a robot can give you control finesse during competitions. Moving a joystick hard right, for example, might have different effects, depending on the robot's speed and direction. So Design by Alton Harkcom, EGO North America, Newnan, GA

Color Sensor for Robot - i'm developing a simple, active, color, object sensor for my robots based on three ultra-bright LEDs. An old-fashioned cadmium-sulfide sensor detects the brightness of the reflected red, green, and blue as each is turned on individually. __ Contact David Cook
Colour-Sensing Robot with MATLAB - A camera is one of the most powerful and accurate sensors if you know how to process the images taken by it for the information you want. You can process subsequent...__ Electronics Projects for You
Controlling a Robotic Car through MatlAB Gui - This project presents the implementation of a MATLAB based graphical user interface (GUi) to control the movement of a robotic car. The commands to move the car in forward, reverse, right...__ Electronics Projects for You
Cricket Chipper Sound Generator - Here is the aluminum "angle bar" I used. it's easy to cut and drill. The size I picked out is 1/16" X 1/2" X 3/4" and the sides are just short of 7". The notch cut on the angle bar is about 2" in from the front (the length of your servo from front to back mounts). Your cross pieces can be any length, but I made mine the size of my IC PCB (standard IC PCB from Radio Shack). __ Credit to Sparky
CW2 Walkers - Slightly more complex than CW1 and will make your walker turn when it encounters an object. __ Contact Nervous nets © and patented Mark Tilden. Content originally developed Ian Bernstein
Cybug-the Solar Fly - This simple robot is a great first kit to build. it's Cybug, The Solar Fly, and he's a real attention-getter.__ SiliconChip
Cyclops Walkbot - A DiY mini desk top bot with a happy hop makes for some good fun. __ Contact Jameco Electronics
D1 SE (Solar Engine) - Charges all day, runs at night. Think noctibot here. __ Contact Nervous nets © and patented Mark Tilden. Content originally developed Ian Bernstein
D1 solar engine solarbotICs - Nocturnal-Controlled Solar Engine: The D1 solar engine is the original nocturnal solar engine design. The design is simple, tuneable, but no longer terribly useful (I include it here just for purposes of education and folks' historical interest). __ Designed by Wilf Rigter
DC Motor-Driver H-Bridge - Physical motion of some form helps differentiate a robot from a computer. it would be nice if a motor could be attached directly to a chip that controlled the movement. But, most chips can't pass enough current or voltage to spin a motor. Also, motors tend to be electrically noisy (spikes) and can slam power back __ Contact David Cook
DI Nocturnal Solar Engine - The D1 solar engine is the original nocturnal solar engine design. The design is simple, tuneable, but no longer terribly useful (I include it here just for purposes of education and folks' historical interest). This design has a number of weaknesses; courtesy of Wilf Rigter, here are a few: __ Contact Eric Seale
Don Roy Robot - what you do with a windfall robot kit that is pretty kewl. Pictures and a Real Movie. __ Designed by DC Reagan
Drink Delivery Vehicle -Inverted Pendulum - 17-Oct-14 -Design News: The DDV-iP is an inverted pendulum driving machine. DDV-iP stands for Drink Delivery Vehicle - Inverted Pendulum. The concept is a two-wheeled self-balancing robot that can deliver cold beverages to thirsty folks on hot summer days. A wireless RF remote enables manual control of the device beyond __ Gadget Freak-Case #264
Driving high-power loads with a microprocessor - This tutorial offers suggestions about controlling large loads with a microprocessor. This is often an issue with those building robots who need to control devices such as lights, motors, vacuums, and other accessories found on robots. We will only deal here with devices that need to be switched ON and OFF - not devices that need the power reversed. Obviously drive motors and other devices need to be switched ON/OFF and also have the power reversed in order to reverse the direction of the motors. That normally requires an H-bridge which is a much more complicated circuit. __ Designed by Roger Arrick
DSSSE - Type 1 (Voltage Controlled) Solar Engine - if you had time to experiment with the ALF type SE circuit you may have discovered some of its shortcomings with regard to a Power Smart Head adaptation. The problem is that HCMOS
gates are power hungry when used as SE voltage comparators when the analog input voltage is near the CMOS
switching threshold. if an HCMOS
gate is used without sampling, the chip supply current can be as high as 70mA with the comparator input voltage near the trigger threshold (Vcc / 2). __ Designed by Wilf Rigter
Dual DC Motor Speed Controllers Navigate Robots - 03/29/01 EDN Design Ideas: Mobile robots need simple and lightweight dc-motor-speed-control hardware that can work with low-power batteries. Flip-flop type navigation systems allow only one motor to operate at a time while the other motor remains off. Navigation direction changes Design by Shyam Sunder Tiwari, Robotics Software Pvt Ltd, Gwalior, India
Dual Fan Controller - A birthday present gone too far. An overengineered temperature-based automatic twin fan controller with brass face to keep a kitchen PC cool. __ Contact David Cook
