This tutorial details the construction of a simple and low cost robot.
The robot is mainly a line follower but can also be used as a photovore,
a photophobe, and obstacle avoider!And all this for less than 40$. The
best part is that the robot does not use any microcontroller, which
means you need no expensive programmer or even a computer to program
your robot. This tutorial is mainly aimed at beginners, hence I have
tried to keep the robot as simple and cheap as possible. With only a few
parts you can get this robot up and going.
Here is a video of the robot following black line.
4. Identify colors to be able to locate green and aluminum victims.
VIDEOS OF THE ROBOT IN ACTION
GOAL: This robot will be
built to compete in the 2008 Robocup Junior Rescue competition. In this
competition the robot must " follow a black line which twi

After three years of robot building and still having to learn
more and learning day by day I can say that I gathered enough experience
to build a robot out of a toy. All I needed was some basic tools (screw
driver, driller, e.t.c.) a toy, to be used as a base some electronics
(Two OEM Basic Stamp chips, photoresistors, IR leds and decoders e.t.c.)
some plastic sheets and some metal stand offs...
The basic idea
was building a almost totally autonomous robot capable of recharging
itself by a top-level solar panel but not having enough money is a
serious problem (I have already gone over-budget but it was worth
trying). The solar panel needed for recharging the NiMH battery in a
reasonable time (4 hour charge aprox.) costed 60Euro ( 12V @ 5W). Also
by the end of the month a change in prices is expected in my country
(Hellas - Greece). But even without having a solar panel the proccess
can by analysed (program code - video cover - algorithm) and it will be

Objective: To create from scratch a working robot that is able to avoid walls and obstacles.
Ever wanted to make a robot that could actually do something, but never
had the time or knowledge to do it? Fear no more, this instructable is
just for you! I will show you step by step how to make all the necessary
parts, and programs to get your very own robot up and running. I was
first inspired to build a robot when I was ten, and saw Lost in Space,
with that famous B-9 robot, I wanted one! Well six years later I finally
built a working robot, its name- Walbot of course!
Plastics
It should not be hard to convince anyone the benefit of using plastics
instead of metals for so many applications. Cars, clothes, food containers,
toys - these are all items that have been revolutionized by the invention
of plastics.
Plastic is cheaper, lighter, more corrosion proof, easier to cut and shape
and drill, has a very low thermal conductivity, and a higher strength to weight
ratio than metals. So why isn't your robot made of plastic already?
It is probably because you do not know where you can get large cheap
quantities of the stuff, nor have you actually realized the advantages of it.
HDPE, or High Density PolyEthylene
The type of plastic I will talk about is HDPE. The reason why I choose this
particular white colored plastic over any other is because it is the cheapest,
and yet still has all the good propert

The forest robot, R-8 is a remote controlled robot
that is capable of scouting a forest environment and taking high
resolution images of what it finds.
It has a video and remote control range of over 1000 feet in a dense
forest. It has a transmitting video camera and a high res still camera.
It has a
roaming time of about one hour. The wheels are 1/2" plywood wrapped with
wire and powered by four 12v gear motors. Their traction on dirt and
rocks is quite impressive.
Details:
Mobility: 4 gear motors- 4 wheel drive with two motors pivoting to allow it to clear 3 inch obstacles.
