<p>Karim,</p>
<p>I think 2003 was when the nBot was first published. Looks like
this fellow has a very robust platform. Kudos to anyone who can
make a robot balance. <br>
</p>
<p>I will say there are now lots of two wheel balancers out there.
Most seem to be content to get the platform to balance and they
are done. Most of the videos, like these, are just of the
platform balancing. Not many take the next logical step and add
sensors and behaviors. (You know, like nBot). <br>
</p>
<p>My experience has been that introduces a whole new level of
challenge.</p>
<p>cheers!</p>
<p>David</p>

<div dir="ltr">My youtube binge on harmonic and cycloidal drives
eventually let me to the GearDownForWhat channel where I
stumbled over this:

<div>This video is of a 2 wheel balancing "car". It's not brand
new, but it was new to me. The guy does share a simple
overview of the control theory. </div>
<div><br>
</div>
<div>Anyhow, this video made me think of nBot and how different
a mindset this guy's approach seems to be. If David's is a
closer-to--NASA (or really any kind of professional
engineering mindset), then this fellow is more like an extreme
sports enthusiast or toymaker. Both are interesting
approaches, and sometimes a free-for-all attitude can push the
envelope of what is considered reasonable or useful.<br>
<br>

<div>And if you're not familiar with David's nBot:<a

nBot is around 18 years old now? I remember when it was just a
baby - David demoed the inverted pendulum bot at the Bill J.
Priest Institute back in the day. Time to head off to
college...<br>

<div>David, consider yourself poked for a response.<br>
