The present disclosure may relate to a computer readable medium containing instructions that include obtaining a first signal corresponding to an idler roller guide speed, obtaining a second signal corresponding to a tire speed, and obtaining a third signal corresponding to a motor speed. The instructions may also include comparing the idler roller guide speed to an idler threshold based on a relationship between the idler roller guide speed, the tire speed, and the motor speed and comparing the motor speed to a motor threshold based on the relationship. The instructions may additionally include, based on one or both of the idler roller guide speed exceeding the idler threshold and the motor speed exceeding the motor threshold, determining that a slippage has occurred, and in response to the slippage, initiating a corrective action.

1. A method comprising: driving a wheel, the wheel including a drive roller guide, an idler roller guide, and a centerless rim, the drive roller guide and the idler roller guide configured to roll along the centerless rim, driving the wheel including: operating a motor coupled to the drive roller guide;by operating the motor, rotating the drive roller guide to cause the centerless rim of the wheel to rotate based on friction between the drive roller guide and the centerless rim;monitoring a motor speed of the motor with a first sensor, an idler roller guide speed of the idler roller guide with a second sensor, and a wheel speed of the wheel with a third sensor;determining, based on a numerical relationship between the motor speed, the idler roller guide speed, and the wheel speed, that slippage is occurring between the drive roller guide and the centerless rim; andbased on slippage occurring, taking a corrective action to increase friction between the drive roller guide and the centerless rim. 2. The method of claim 1, further comprising: based on a numerical relationship between the motor speed, the idler roller guide speed, and the wheel speed, determining that the slippage has ended; andbased on the end of the slippage, stopping the corrective action. 3. The method of claim 1, wherein the corrective action comprises activating a mechanical device to push the drive roller guide towards the centerless rim. 4. The method of claim 3, wherein the mechanical device includes a spring-loaded pivot such that as the mechanical device is activated to push the drive roller guide towards the centerless rim, a spring is compressed. 5. The method of claim 4, wherein deactivation of the mechanical device causes the spring to push the drive roller guide away from the centerless rim. 6. The method of claim 1, wherein the corrective action comprises activating a pneumatic device to inflate the drive roller guide. 7. The method of claim 1, wherein the numerical relationship correlates a rotational speed of the motor with a rotation speed of the drive roller guide, correlates the drive roller guide speed with idler roller guide speed, and correlates the drive roller guide speed and the idler roller guide speed with the wheel speed. 8. The method of claim 7, wherein determining that slippage is occurring between the drive roller guide and the centerless rim includes determining that the idler roller guide speed, the drive roller guide speed, or both, are faster than a relative threshold speed based on a correlation between the drive roller guide speed and the idler roller guide speed and the wheel speed.
