Obstacle detection for blind people using ultrasonic sensors in LabVIEW possible??

[8056547145]

I am doing a project using ultrasonic sensors to detect the obstacle and its distance from the blind people and using microcontroller and headphones convey the related information to the blind people.  Before starting with the hardware i would like to know if it is possible to do the same using Labview software and test the solutions??

There is no such thing as doing the same thing in software as you do in hardware.  Ultimately you will need the hardware to interact with the real world.  Fortunately, LabVIEW is a full-fledged programming language that enables easier connections to reworld sensors.

If you don't have sensors yet, then you can certainly try to do more programming in LabVIEW that could simulate the behavior of the sensors.

It would be possible to emulate an environment and determine the emulated sensor input in order to test your obstacle detection vi. This is actually good practice since it provides repeatable sensor inputs for testing or for development when the sensors aren't available.

i would like to know if its possible to fuse the labview and harware microcontroller?? i am new to labview.  Once using sensors in labview, is it possible to use hardware to do further processing of the signal obtained from sensors in labview???

The LEGO MindStorm is a kit that includes a NXT brick, which is a computer in a 5x3x1 (roughly) package, and it includes unltrasonic sensors, motors, other sensors and stuff.

It runs a variant of LabVIEW See here, that is geared toward robotics.

My son (age 11 then) did a project where hebuilt a vehicle that would sense obstructions and stop, then try to avoid them.

He did the programming on his MacBook, it works on Windows too.

I don't know what you mean exactly by "fuse the hardware and software" but that seems pretty close to me.

I'm not sure what you're after here.  LabVIEW is more than just data acquisition. Any processing you can dream up can be done in LabVIEW.

fuse i meant like if i could do a part of project in software and the later part of microcontroller and speakers in hardware??

Have anyone has done this proj using labview previosuly ?
