<p>I just posted your competition on my Autonomous Robot
Competitions Facebook page. The page is a closed group so you
shouldn't get bombarded with spam, but may get some competitors
from other locations. The page is at

you don't want this. <br>

<p>Sample Retrieval is like the NASA Sample Return I did back in
2013 but in a smaller area. It's a nice challenge. I think you
need a time limit on how long a robot can attempt to retrieve the
items.</p>
<p>My personal feeling is that Four Corners is an outmoded
competition, although I can see the interest. When it was started
the only way to navigate for hobby level robots was dead reckoning
so precise odometry was necessary. Today's navigation is vision,
IMU, etc and the precision measured by Four Corners isn't
necessary. Correction and adjustment of position is done through
other sensors. <br>

<div dir="ltr">-All,
<div> I am preparing the announcement of Roborama 2019, and
am trying to sort the contests by difficulty. How would you
gauge the Four Corners competition vs. Table Top - Classic?</div>
<div><br>
</div>
<div>To refresh your memory, Four Corners, the robot drives
around a large square course and attempts to end at the same
location that it started. In Table Top - Classic, the robot
is placed on a table and must do 3 tasks: drive to the
opposite edge of the table with some part of the robot over
the edge and return to the start area, knock a soda can off
the table, and lastly, push a soda can to edge where a box
is located so the can falls into the box.</div>
<div><br>
</div>
<div>I initially thought that being successful in Four Corners
is harder, than doing the tasks in Table Top - Classic. My
thought was the robot needed to be more precise and capable
in Four Corners, where in Table Top - Classic there are many
ways to solve the problem. With this in mind, I gauged Table
Top - Classic to be a high level beginner contest and Four
Corners to be an intermediate level contest. </div>

<div>What do you guys and gals think?</div>
