need help with the $40 robot

[hate_forever143]

cut five 5 cm long wires and add molex connectors to each
are these molex connectors necessary..
and how does the robot avoid obstacles and then detect the line again..

[Admin]

Connectors aren't really neccessary, but they make your wiring easier to modify and work with. You can just solder the wires in if you really want.

the rest is explained in the tutorial . . .

the robot does not detect obstacles AND go on the line

it does only one at a time

cannot do both

my robot can do both

The $40 robot can do both obstacle avoiding(can avoid shadows cast by objects) and black line following at the same time.
To use the robot as a obstacle avoider and black line follower follow the method given at http://www.societyofrobots.com/member_tutorials/node/66

Really?

It can follow a line, avoid an obstacle on the line, and retake the line again?

Still very cool stuff.

How is this only $40s?There is so much stuff!

[Pratheek]

The $40 robot does not use any microcontroller, which cuts down the cost of a programmer and the microcontroller itself.

Actually, the DC motors are the most expensive parts of the robot. More than half of the money is spent on the motors. So if you already have DC motors, you will only need another $20 to build the robot.

do u think u could make it even less expensive?

[Pratheek]

Yes of course. I purchased all the parts from a local hobby shop and the whole robot costed around 600 Indian rupees, which is almost $15.
