Verbal Skills and NLP

I'm starting this forum for discussing verbal skills in robots including but not limited to natural language processing.  I'd like this to be a place to discuss conventional and out of the box ideas for improving verbal skills in robots.  This could involve:

Simplified occupancy grid mapping

I have a setup, where a distance sensor, such as sonar or IR, rotates about 180 degrees and takes a distance measurement every few degrees. What I would like to do is to create a occupancy grid out of these measurements on an Arduino or, more specifically, I would like to compare two different algorithms, which create the grids.
One of these algorithms would be made by myself, but in order to make a solid comparison, I would like the other algorithm to be the one which is mentioned in occupancy grid materials and research papers, which utilizes a binary Bayes filter.
All my project ideas needed CNC motion, which was due, at least in my shop, for a standardized approach which will hopefully classify the extruder, laser diode, and … Read more

How to make a medium size robot. Let's make a guide!

Now we have wonderful tutorials for making beginners and small robots, but bigger robot need stronger frame, motors, bigger batteries and can do much more work.

There are good examples of medium size robots here, but it would be useful to me and maybe others if there is a good comparison of various motors and drivers, how to get them and what to care about to avoid crashes and dangers.
