DreamMaker Overlord sneak preview

Well, it's time to inform you that the DreamMaker Overlord is launching on Kickstarter soon. 

What is the Overlord? 

Overlord is a FFF (Fused Filament Fabrication) delta 3D printer with a build volume of 150mmD x 160mmH (OverLord) or 170mmD x 260mmH (OverLord Pro). The 3D printer is capable of printing PLA or ABS, uses automatic leveling for precise printing, pause/resume function and many other new features.

inspired by BOB by badji here at LMR, i wanted to build my own four servo biped walker after i kind of failed on the rather complicated 12 servo ROFI. i love BOB's … Read more

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
