Robotics Startup Makes "Lego-Like" Modular Robots

About half-way down, there is some useful information about this SBIR-funded, bootstrapped company:

Personally, I'm most interested in Modular Robotics' back-story -- how they got funding and the trials and tribulations they faced while creating their first product. The story is fantastic, and laid out for everyone to see on their very honest and open blog: From SBIR funding ($100k Phase I and $500k Phase II); to Crowdsourced packaging design (despite their nomenclature misgivings); to hardware design woes; and Chinese production issues

While the HN community seems predominantly software-based, the hardware startup scene seems to have some additional challenges.
