RelativeAccelerationSensor ​

Ideal sensor to measure the relative angular acceleration between two splines

This component extends from PartialRelativeSensor

Usage ​

RelativeAccelerationSensor()

Connectors ​

  • spline_a - (Spline)

  • spline_b - (Spline)

  • a_rel - This connector represents a real signal as an output from a component (RealOutput)

Variables ​

NameDescriptionUnits
phi_relRelative angle between two splinesrad
w_relRelative angular velocity between two splinesrad/s
