PowerSmart Solar Speeder, V2 - This must be the most efficient bipolar transistor motor driver design for this application and I recommend it for the solar roller competitions. A 1381E is used to trigger at 2.4V. While it takes a total of 10 components plus motor compared to the stock circuit's 6 components, you will clearly get better performance compared to a stock Solar Roller/Speeder circuit. __ Designed by Wifl Rigter
Printed Board for Sandwich - Stuffing instructions for a professional, double-sided, printed circuit board for Sandwich. The board has silkscreened part numbers and a solder mask, making it a fast, easy, and reliable way to build. __ Contact David Cook
Programmable path navigator Robot - The project achieves complete concept, design and development of a programmable path grid navigator robot. The project deals with the design and development of the mechanical, hardware, embedded software and the user interface (for path feeding) aspects of the robot. The developed robot is a fully functional wireless robot. __
Programmable Robot - Here's a great school project! This robot features full manoeuvrability, speed control, bump-and-respond logic and programmable sound and light sensing. Turn it loose and watch it head for the light.__ SiliconChip
Puff1 - A steam powered robot! __ Designed by DC Reagan
Pummers - The PowerSaver Flasher uses capacitive output coupling to produce brighter shorter flashes and has a much lower average current drain than standard bicore or 74HC14 flashers. The PS Flasher with one LED circuit (2 LEDs) runs all night from a 1F capacitor charged to 5.5V. Up to 12 LEDs can be controlled with __ Designed by Wilf Rigter
Pummers - The PowerSaver Flasher uses capacitive output coupling to produce brighter shorter flashes and has a much lower average current drain than standard bicore or 74HC14 flashers. The PS Flasher with one LED circuit (2 LEDs) runs all night from a 1F capacitor charged to 5.5V. Up to 12 LEDs can be controlled with one 74HC14 flasher and probably would run for 2 hours from a full charge. Use a range of timing resistors between 1M and 4.7M for each oscillator to give a random light show appearance. __ Designed by Wifl Rigter
PWM PIC with Direction Pins Latched - Scroll down for this project. ____ Designed by Dennis Clark
Repairs & Improvements - Visit Sweet, Roundabout, Hard2C, and Chicago for a weekend of simple fixes for line following, mini sumo, and solar power. See how different types of screws can help a robot slide, hide, and hold onto a gear. __ Contact David Cook
Reversing H-bridge - This H-bridge variant was one of the first in which the reversing circuitry is built into the driver, rather than (as is more-commonly done) into the control circuitry upstream of the driver. This is a handy circuit, though, for 2-motor walkers -as all that is required to reverse one is to reverse the phasing of one of the motors. __ Designed by Wilf Rigter

This is a handy circuit, though, for 2-motor walkers -- as all that is required to reverse one is to reverse the phasing of one of the motors. it is built from 4 transistors and a mux. __ Designed by Wilf Rigter
RF Control for a Robot - Controlling a robot with RF from a PC __ Designed by DC Reagan
RF Modem RobotICs Project - 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 receivers. When I started out I didn't realize that the larger breadboard I was working off of was causing a lot of the signal deviance because the metal traces on the breadboard worked like small capacitors and changed my circuit Dynamics. So after much research I found the Reynolds Electronics RWS and TWS 434 RX/TX pair __ Designed by Rob Arnold
RF Remote Control System - With a handful of inexpensive components, a little creativity, and the power of PicBasic, you can build some pretty outstanding robotics creations as Rob Arnold proves with his Ruf-Bot project. __ Designed by Rob Arnold
RF-Based Dual-Mode Robot - Here is a dual-mode robot that can be operated manually using an RF-based remote control and can also move automatically avoiding all the obstacles. The robot has some inbuilt intelligence to...__ Electronics Projects for You
Robocar with Wireless Steering - We have seen many projects where a robot is controlled by a remote controller. Here we describe a robot that can be steered in any direction just like you drive your...__ Electronics Projects for You
Robot Beacon - One of the biggest hurdles to overcome is the "image" of the PIC 12C508A chip. We tend to think of it as a single chip, just like any other 8-pin chip. But it's not. it's really equivalent to 5, 6, 8 or even more chips in a single package! And each chip can be programmed to do almost exactly what you want! __ Designed by Collin Mitchell
Robot Beacon rotating light using PIC12C508 - Robot Beacon uses a PIC 12C508A OTP (One Time Programmable) 8-pin microcontroller. There is a lot of controversy over the type of microcontroller that should be promoted in a project such as this. There are at least three manufacturers of microcontrollers suitable for this application and it's a nightmare trying to work out the best type to promote. __ Designed by Collin Mitchell
Robot Voice Generator Project - Those of you who imagine that a robot voice generator box would require a whole heap of ICs are mistaken; the iSD2500 ChipCorder family of ICs from Winbond contains almost all the necessary hardware in a single IC to record and playback audio messages. included on the IC is a microphone preamp and AGC suitable for a low-cost __ Designed by Popescu Marian
Robot wars: start here! - We get quite a lot of of enquiries from would-be contestants for Robot Wars who don't know where to start building their robot. I sometimes get the impression that they are starting with the controller - which is the wrong end of the design chain. As a general rule, when designing a machine, you should design a mechanism that will do exactly what is required before you start working out how to control it __ Designed by Richard Torrens

Robot-JavaBot1 - 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 curves. The software still has lot's of room for improvement but works well as is. __ Designed by Peter Jakab
Roundabout - This is an all-in-one intermediate-level robot that can explore rooms, avoid obstacles, follow lines, and compete in mini sumo (see the movies). The robot can be made in a variety of body styles with either a logic chip or microcontroller brain. __ Contact David Cook
