<tt>Hi Eric, All,<br>
<br>
Gethub has rover plans:<br>

<br>
However, I can't view .IGS or .STEP files. Maybe some PDFs
somewhere? Might be able to work from good JPGs. Looks like a
lot of aluminum channel (</tt><tt>Actobotics channel). Maybe
build it with Lynx Motion parts?<br>
<br>
Rocker-Bogie Assembly 3D View.PDF Ah! But problems with PDFs and
XLSX files. <br>

<div>I have always wanted to build a Rocker-Bogie chassis
Robot. I've got some rough terrain to use for my own version
of RoboColumbus that I thought would be a perfect candidate
for a Rocker-Bogie chassis. However JPL's Open Source Rover
Website hates me!

Maybe rather than $2500 for JPL's Rover build I can get my
kicks out of this PVC Rocker-Bogie build?</div>

<div class="gmail_extra">I noticed David Anderson mentioned
they ruled out Rocker-Bogie chassis when planning jBot for
lack of speed. While it is pretty much true it must come to
complete stop when climbing over a large obstacle, what is
the alternative? </div>
<div class="gmail_extra">Avoidance? Maybe the Boston Dynamics
Sand Flea solution? jajaja.<br>

seems to pretty robustly climb over obstacles although has
a little bit of climbing pause when climbing stairs --
especially the initial step and whenever the front wheels
are not already airborne...</div>
Very nice videos on your jBot page David! Thanks for
sharing.<br class="gmail-Apple-interchange-newline">
