The Roboteq Calculator applies fundamental laws of physics to estimate the torque needed to drive your vehicle, based on a specified acceleration profile. You can adjust various parameters, including the vehicle's weight, desired acceleration, number of drive motors, inclination, and more. Ultimately, the calculator determines the required current for each wheel. This calculated value is essential for sizing the motor or motor drive in your application.

Important Note 

Always include a margin for error in the calculated values, as not all system aspects can be accurately modeled.

Disclaimer

While we have tested the calculator and found it to yield realistically close results, we cannot guarantee absolute accuracy in all applications. Therefore, the values provided should be used only as a starting point for your development. Roboteq is not liable for any discrepancies between the theoretical calculations and actual outcomes.

The movement of an Automated Guided Vehicle is influenced by three key physical factors: inertia, rolling resistance, and gravitational force due to weight. Inertia, which is a property related to the AGV's mass, primarily impacts the vehicle during acceleration and deceleration. Rolling resistance arises from the deformation of the wheels and continuously opposes the AGV's movement. The gravitational force due to the AGV’s weight becomes a significant factor on inclined surfaces.

The equations to calculate the torque required to overcome the vehicle's rolling resistance, the traction torque needed for acceleration, and the gravitational torque necessary to counterbalance the vehicle's weight on inclined surfaces are as follows. The final required torque per wheel can be determined by summing these three torque values.
