Introduction Impulse-momentum contact Point contact Friction forces Contact in robot dynamics modelling Conclusions Limitations Not useful for prolonged contact Cannot solve for contact or reaction forces May not be very useful in robotic or other multibody systems While simple impulse-momentum models may not be useful, the concept of a coefficient of restitution may still be important in other models.
