Autonomous RC Car II (with wireless camera!)



I've finally got a nice and cheap wireless camera! It cost me around Rs. 1200 (USD $24). I quickly fixed this camera to my autonomous RC car and now the connection between the RC car and my computer, is completely wireless. As before, the 'brain' of this robot still resides in my computer. If the computer sees the the car approaching an obstacle, it stops it and turns it around. Check out the video above to see it in action!

Hey ashish!
this is Avik...
well, it was nice to hear from you!!!
i would like to suggest a few things to you wihch i have been trying but, have not been able to do...

Try out some joystick programming manuals available on the net...and try to control your RC car by that...
i have been working on this...(but in VB)...
you may also want to program your car to move 5 seconds forward, then turn left, then turn right and so on...For this , you may try out KEMO relais timer and set the timings...
but, i think all these might be use less to you cuz your car is autonomous!!!
if you ever get some time, please make a program to control the car via joystick for me...
and, i tried out your keyboard program...
it is not woking well on my PC.
when i direct it to go forward, it does go forward but, always stays to the left...
thankz...

You are dooing some nice things man!
I have some questions about this project:
At what distance is the car programmed to stop?
Can you determine the distance betwin the car and thestationary object?
What if the car detects an moving object on it's direction of moovement?(the laser is pointing against another toycar).
I'm asking you this because i have a similar project in wich i use a camera for a car to follow another car exactly on the same path and until now i managed to control only the direction of the moovement. I still have to control the distance:) maybe you can help me!
Keep up the good work!

Ashish Derhgawen said...

Hello George,

The computer doesn't calculate the actual distance between the car and the obstacle in front of it. It just determines the position of the laser dot in the webcam's field of view. Based on its position, it determines how far/close the obstacle is.

Can I determine the actual distance between the obstacle and the car? I guess I can: http://ashishrd.blogspot.com/2006/11/obstacle-detector-using-webcam-and.html

If a moving object comes in front of this autonomous RC car...I think it would follow it..without getting too close. :)

Choosing a car is bit difficult , since in the market wide range of cars are available. You need to consult an expert who can compare different branded cars. I prefer Eu Neuwagen to consult and get the right brand.
