navigation

Last week my Rover 5 completed his first tour in our living room avoiding obstacles / no bumping ;-).

The Rover has the following sensors / inputs:

I just found an interesting article that has me very intrigued. Time to order a compass.

Hi, I am willing to built a stereoscopic navigation system (which will have 2 paralel webcams to capture images every X second and compare images with each other to find depth)  just for fun and coding challenge(more challenge actually) but i have no idea how to do that, i am searching and reading sources with all kind. however since i have no idea where to start more i read it makes me feel more confused and i cannot find a complete guide to follow.

Hello All

Me again, flogging a (hopefully not) dead horse.

I wonder if anyone can provide links/guidance/code/insight into dead reckoning programming using the various (relatively) low cost components available to us.

I am thinking of things such as gyroscopes, accelerometers, magnometers etc. At this point I am excluding wheel encoders (since my vehicle is tracked and suffers from slipping tracks) or any form of external input such as beacons or gps etc.

Hi All

It must be that my previous question https://www.robotshop.com/letsmakerobots/node/28808 was wrongly phrased as I am sure there are plenty of knowledgable people here. Anyway, I will try re-phrase my question.

Could anyone be so kind as to tell me what components would make for a complete navigation module. ie. a module that knows where it is.

I am asking in terms of a small household or garden robot so GPS is probably not relevant.

We are so dead

Hi, just got this idea, and thought perhaps it would interest one of the clever guys out there. Hope is that a vendor will take this up, after a couple of clever LMRians have talked more about the details that I am too stupid to get into :)

Another XMOS robot I have found, made by people at University of Denver.

Demonstration of XMOS real-time ability. This test is running 8 independent tasks: gps task, ultra-sonic task, compass task, wifi receive task, wifi transmit task, pwm output task, behavior task, status led task:

Hi,

Im new to this forum, and new to robotics in general. The same could be said abou my knowledge about microprocessors and programming language (other than .html notepad stuff).
 I have some basic knowledge about electronics, but nothing worth braging about.

But, i have been thinking about starting on a new project soon (I'm currently in the finishing stages of a little cnc project i have for cutting out rc airplane foamies...) which i would like to start this fall, and hopefully be done with before next summer.

I am still wondering if it is possible to create a simple, cheap, fairly accurate, directional beacon for outdoor use. And I keep thinking I should try to re-purpose an RC transmitter. So here it goes:

Would you deem it possible to create a directional antenna for an RC transmitter?

Would this antenna be able to rotate? Fully continous, or just 360 CW followed by 360 CCW?

Which RC system would you consider? There are so many frequencies in use. And modulation types.
