A Versatile PIC16F876A Based Robot

Design   Summary: Our group designed  and  manufactured a  miniature  robotic  vehicle  that  conquers  various terrains.    The  vehicle  was designed  with  a  track system  which is  powered  by  two  DC motors. The  motors   use a  Quadruple half  H ‐Driver in  order to  drive the  motors  in  both  directions.   The track system  incorporates a  four  bar linkage  for each  tread.    These two  linkage ...

Pingbot – Micro RC Rechargable Musical Robot Pal using PICAXE

Pingbot is a very small (38mm diameter), usb rechargeable, programmable, musical, remote control robot designed for maximum fun and danceability. I've built a few experimental robots in the past and, to be honest, they all looked the part. They were nothing more than circuit boards with wheels glued on.They did help me learn, but they just didn't feel like completed robots. The main purpose of this project ...

TechBot line following robot using PIC16F84

Design Goal: The TechBot1 is a small line following robot designed for for the 1998 Embedded Systems conference in San Jose California. It was built by Jerry Merrill and myself and was designed as a promotional robot that would follow a black line drawn on a dry erase board.   Motive Power: The TechBot1 uses 2 Cirrus CS-70 servos that have been modified for full rotation and have had their controller boards ...

Line following robot using PIC16F84

Design Goal: 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. Motive Power: The JavaBot1 uses 2 Cirrus CS-70 servos that have been modified for full rotation and have had their controller boards removed to convert them from servos to g ...

Wifi robot vehicle controlled by PIC16F628A

Introduction Wifi Robot: A remote control car that can be driven over the internet or with a laptop wirelessly from up to 500m away. It has a live-feed network camera so that it can be driven without line of sight and a horn so that you can honk at people. A while ago I discovered the Linksys WRT54GL router. It's very hacker-friendly in that it runs Linux and some of the hardware has been reverse engineered ...

RF Modem Robotics Project using PIC16F84 microcontroller

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 ...

Small Virtual Wall for iRobot Roomba using PIC12F629

The Virtual Wallis a circuit to mimic the behaviour of the iRobot Virtual Wall/Lighthouse, provided with the robot. It produces the same infrared pattern and the robot sees it as another virtual wall, blocking its path, while vacuuming. This circuit was built mostly using SMD components to reduce its size, nearly to the size of a 9V battery (PP3/6F22/6LF22/etc). Design Considerations After examining the ori ...

Tiny Remote for iRobot Roomba using PIC12F629

Description The Tiny Remoteis a very compact infrared remote control with only two buttons to control an iRobot Roomba. It produces three different infrared control signals that the robot interprets as Clean, Spot and Virtual Wall/Lighthouse. The circuit is built mostly using SMD components to reduce its size, nearly to the size of a keychain and is powered by a CR2032 coin battery.   Design Considerat ...

Large Dancing Robot using PIC16f877A microcontroller

Large Dancing Robot Build a large dancing robot. This was supposed to be a walking robot, but it more kinda beebopped around. video on last step. Build a Prototype First, The _Prototype_: Before you make a large, high power robot, it's good to make a smaller scale prototype. I made a simple walking robot using = Brains: PIC16f877A, = Actuators: two small geared pager motors (http://www.solarbotics.com/produ ...
