which the contestant can choose to “touch.” If they do,
their time is decreased by a fractional multiplier (x. 5, x. 25,
x.1, etc.). However, the robot must touch the Goal Cone to
get a timed score. Otherwise, the score is the distance from
the Goal Cone.
In spite of the rain that was still pouring down, I made
the RoboMagellan map which featured three bonus cones,
with one in the tall grass with a x.1 multiplier (that equates
to 90% off your time, folks!).
Table Top Navigation is an event that was invented by
the HomeBrew Robotics Club. It’s basically a contest where
the robot deposits a block into a shoebox. It’s not timed
and there are no rules about the robot or table or block
(size, shape, color, etc.). In fact, you can bring your own
table, block, and box if you want. It’s all about the show!
Friday evening, the Table Top Navigation event went
smoothly with five contestants: three from Indonesia; one
representing Germany; and one representing the good old
USA (that was me; Figure 3). The Indonesians
are well skilled at this event with robots that
do each distinctive phase of the TableBot
Challenge. On the first run, robots go from
one end of the table to the other. On the
second run, the robots push the block off the
table; then finally, the robot deposits the block
into a shoebox mounted at the end of the
As mentioned, this event is not timed.
Judges can award points just because they like
the way your robot looks or they like your
V16 (Indonesia) which basically won Gold because the
judges liked the gripper so much. Of course, it performed
well too. Another Indonesian entry, Capit2-V16 won Silver
and Marco Walther took Bronze with his entry, Dexter. My
robot, Buggy1 managed to put the block into the shoebox,
but alas, no medal. Guess I need a fancier gripper.
Saturday morning arrived quickly after a long rainy
night. The doors opened at 12 and RoboMagellan started
at 2. I had some time to burn before RoboMagellan started,
so I amused myself by creating a map with my Neato
PiROS, and autonomously navigated from one corner of the
building to the doorway (yes, I’m easily amused). I also
switched on my other robots (Rocky, Homer, Skully,
BlueDog and Caw, the CrowBot) as spectators began to file
through (Figure 4). Springy-Thingy had to stay behind this
year, but hopefully she’ll be back soon.
At this point, it was 1: 30 pm, so I started handing out
the RoboMagellan maps with instructions for the event.
