with an instrumentation amplifier,
using the schematic shown here.
The net result is that the Melty
bot controller no longer needs to be
recalibrated with a new r1 every time
a part shifts slightly. In fact, this
implementation never needs to
know the actual distance to the
center of mass. By removing this
unknown as a factor in the control
system, your bot will no longer lose
tracking after the first hit takes a
notch out of the weapon. It’s a
major step towards making a Melty
bot robust enough for a combat
application.

GREATEST HITS
● by Kevin Berry
This month, only one builder submitted to
Greatest Hits. Going by the
mystery handle “kkeerroo,”
this Australian fighter
highlights his bot —
“Vendetta” — competing at
Robo Wars 7 in a semi-final
fight against a spinner call
Bender.
Get your greatest hit in
print! Before and after photos,
a brief description of the fight,
and the builder’s name can be
submitted to me at Legendary
Robotics@gmail.com. Or, if you have
Vendetta before.
an action shot that clearly shows
what’s going on, those are welcome
too! These don’t have to be current.
You can (legally) submit anything,
Vendetta after.
clear back to the good old days,
when bots were made out of
wood and builders were made out
of iron. SV
