Softer tires will typically grip better increasing friction. However, softer tires will also squish
down more easily and at some point they won't be able to support the weight of the robot.
Our 10in. Pneumatic tires (https://www.superdroidrobots.com/shop/item.aspx/atr-wheel-and-
shaft-set-pair-8mm-bore-10-inch-pneumatic/1131/) are the heaviest duty standard option.
They have steel rims and steel shafts but since they are bigger in diameter, the motors need
to be geared down so you will have the power to turn. For extreme duty robots we have 13
inch tiller tires (https://www.superdroidrobots.com/shop/item.aspx/robot-drive-wheel-traction-
lug-wheel-13-x-5-00-6-tiller-tire-discontinued/1602/) (see our snowplow robot
(https://www.superdroidrobots.com/shop/item.aspx/new-custom-rc-6wd-robot-with-snow-
plow-sold/1612/)) however they are not a standard option due to their size and weight. If you
would like to put these tires on an ATR please fill out our custom robot request
(https://www.superdroidrobots.com/shop/Custom_Request.aspx) form. We also offer 4 inch
Omni wheels (https://www.superdroidrobots.com/shop/item.aspx/omni-wheel-and-shaft-
assembly-double-row-discontinued/383/) which will eliminate the skidding torque issues with
a pivot turn since they roll sideways. The downside is that they are only 4 inches in diameter
and are not good on side slopes or in outdoor or dirty environments. Another option is our
mecanum wheels (https://www.superdroidrobots.com/shop/item.aspx/4-inch-nexus-
mecanum-wheels-high-capacity-set-of-4/1352/), which are comprised of a series of rollers
mounted so that their axis of rotation is 45 to the axis of the main wheel. These wheels allow
your robot to drive forward and backward as well as vector side to side.
Most of our ATR kits use a single axle that is supported with a bearing, then coupled to the
gear motors. See mechanical descriptions below. The DB ATRs use a shaft that is supported
with two bearings, then chain driven. Using this method removes all the dead load from
weight off the motors.
Another factor to consider is how the robot is going to be used with regards to duty cycle. A
robot controlled by an RC controller for fun is far different from one that used for industrial
applications. In industrial settings, our robots motors are run 100% and often autonomously.
If running autonomously, stalling conditions must be taken into consideration. If a motor is
held in a stall condition for too long the motors will burn up. If you are running a heavy duty
cycle you will want the robot to be on the lighter side of its limits and use higher torque
motors so they will not overheat and wear out prematurely.
