@palmisano Is there a map I could see or an array where you store the data. Anywhere I get better description of your mapping algorithm? I will build my 1. robot soon and want it to 2d map my room. I would be very interested to know how you do it in 3d.
@palmisano Already did it yesterday :) You write about 2d mapping using array and wave front alg. You write then that 3d mapping is done with expensive 3d LIDARs. Thats why Iam curios how you do 3d mapping with simple IR finders.
@shebotnov Ah! Well, the ERP takes multiple 2D scans and treats each as 2D. But as each scan is at a different head angle, it is in effect a 3D scan. (a 3D scan using a 2D algorithm, if that makes sense)
Excellent hardware platform; I can see you have a CMOS camera on the turrent mount as well as the sharp rangefinder for future machine vision tests. I would suggest using an electronic compass chip (honeywell do a good and not too expensive one) to help constrain the drift of the map as your robot rotates/moves. What do you program the Microcontroller in, C? Also, appreciate it's only a test but a left to right to left and up to down to up scanning motion for the sensor array would be smoother.
@DarkmoonUK nah, a compass is very inaccurate inside like this. Yeap, I program in C. And yea, its very inefficient scanning, but its just a test for something more advanced later on.
Nope, at least not yet. The map badly drifts as the robot rotates, so it recreates the map on every scan. Sharing the map would be pointless. In the long term I plan to add GPS, and that will solve the map drifting problem.
Awesome! I was planning of making something like this in the future.. Once I get better at robotics, I might try to make a faster one than this. (not to say it's bad..)
Why do you call it 3d scanning if its only 2d. Or am I mistaked?

@shebotnov It's taking measurements of 3D space, meaning locating objects in X, Y, and Z.

@palmisano thats what I thought =) Thx. Didnt you write about this algo anywhere? Forums, site etc ?
Iam very interested in it.

@shebotnov Just those links, really. The source code is all available for download.

does it wok for scanning or is it only good for mounting on a bot solid?
cory1915 2 years ago
It works for scanning. Whats a 'bot solid'?

solid mount sorry

If there were any other robots, would you be able to use the data created by this robot for the other ones?
