BaneBots Large Wheels
Diameter: 2-7/
8-4-7/8 inches
Tread Width: 0.8
inches
Weight: 62 g-143 g
Cost: $5.30-$6.80
Comments:
These wheels are
often found on 12
and 30 lb robots.
The range of
available durometers
(Shore A 30, 40, and
50), size options,
low cost, and easy
mounting make them a fantastic option for large bots.
The 30A wheels have the best grip, but tend to wear out
very quickly if you're trying to put a lot of power through
them. The 40A wheels have a bit more longevity without
sacrificing much traction.
The 50A wheels (which can be bought at www.
banebots.com) are the hardest of the bunch and are
durable enough that even aggressively driven robots can
often go a full event on a set of wheels. The ease of use
and near disposable price range make them one of the
better 12-30 lb robot wheel options. The large BaneBots
wheels are available with a range of mount
options including two hex bores, two keyed
bores, and two plain bores.
BaneBots
Small Wheels
With Hex Hub
Diameter: 1-3/8-2-7/8
inches
Tread Width:
0.4 inches
Weight: 11. 4 g-28.4
g (wheel and hub)
Cost: $6.50-$7.69
(wheel and hub)
Comments:
The smaller BaneBots
wheels are essentially
the same as the larger
wheels. The primary difference is that the small wheels
are designed to use a separate aluminum hex hub. With
bots weighing 3 lb or less, the 30A tread doesn't have
nearly the issues with wear that it does on a 12 lb+
robot. You can use the higher durometer treads, but
there's not much point.
These wheels give fantastic traction, but the design
does have a drawback when compared to its
competitors: The solid wheel and hub results in higher
forces being transmitted to the shaft. If you use these
wheels, make sure to support them well and —
if possible — isolate them from the output shaft
of the drive gearbox.

The Colson
Performa is one of the longest used wheels in robot
combat. It's a durable caster type wheel with a
reasonable amount of grip, with a very long useful life.
The BattleKits wheel provides the only ready-to-install
chain driven wheel on the market. This wheel is designed
to be mounted on a dead axle and driven by roller chain.
This arrangement makes it easy to build a 4WD bot with
only two drive gearboxes, or to build a drive system that
protects the gearbox shaft from direct weapon impacts.
(For example, the front wheels have the sprockets toward
the robot body; the rear ones are away from the robot
body with two sprockets on the gearbox shaft.)
One way to get extra life out of the wheel and hub
combination is to buy extra casters and use a broach to
cut the matching keyway in them. This can be done
properly with an arbor press or (lacking that) a drill press
and some creativity. Short of taking damage in
combat, you can expect these wheels to last a
long time.
