VI for autonomous vehicle

[Kujooz]

Hi,

We are building an autonomous vehicle. Since it is much costlier, we will be implementing it in a prototype vehicle, capable of carrying a laptop on it.It is run by a dc motor and steering is governed by stepper/servo motor. The front panel of the VI is displayed in the laptop as dashboard of the vehicle. Features of the vehicle are line tracing and obstacle detection (using webcam). By pressing the left-right switch in the laptop display(front panel), the vehicle should turn left-right at junctions. Also there are some provisions for monitoring certain internal parameter like fuel level, temperature, seat belt, door lock etc. We are using NI USB DAQ 6009 for data acquisition. Can anyone help us in building the VI?

What kind of 'help' are you looking for? If you are looking for suggestions to improve your code, or find better ways to program, go ahead and post your questions on the forums and we should be able to help you out.

Similarly, if you are looking for someone to write the code, you should look at the listings for the Alliance members. Autonomous vehicle control is a Very Non-Trivial project, otherwise the US DARPA agency wouldn't have offered large prizes in their competition to achieve that.

As the previous poster indicated, if you want recommendations on code you have written, this is the place.

Thank u for your response...

We are actually implementing it on a toy car...we just want it to detect obstacles using camera (we are using a USB webcam) and avoid it...but the problem we are having is that we are new to labview and we dont know how to process the image using the labview vision assistant...so can u help with how to acquire and process the image to find obstacles...it will be more helpful if the system shows the obstacles highlighted in any colour...

There is a "Machine Vision" forum on this site where you might have better luck getting the answers you need

You may also want to check out the activity related to FIRST. FIRST is a robotics competition and one aspect of it is an autonomous mode.

You might check this out. Probably doesn't help but from your project description it is probably of great interest to you.

Hello sir,

I am trying to implement GPS based Navigation system on my scale robot, I am finding difficult to route the information through the USB GPS receiver, can u send me a sample VI for GPS based autonomous systems?

Not to discourage anyone from taking on tasks such as this but we had the same project and 5 of us spend day and night for 6 months to implement it. It is not a project that you can be done through forums and over night. I'd be more than glad to help, but you need to be more specific. For example let us know if you need help with a specific pressure sensor, or Laser/sonar object detector, IMUs or steering.

As far as receiving GPS Data, I need to know which receiver you are using and whether it decodes the message or not. If the receiver does not decode the message, writing code to do so is not very trivial specially if you are looking into filtering them.

yes, definitely i recognize the magnitude of designing such a system, but my case of building a VI for small servo steering consisting JUST two inputs,

one is the SONAR(left and right) sensor other one is an GPS reciever.

do u think we can build a control system VI under shorter period of 1.5 months? using these two inputs?
