To investigate the instantaneous properties of a planar motion, Roth and Bottema [1] obtain the instantaneous invariants of a planar motion using Veldkamp’s canonical frame [7]. We investigate the derivatives of time-independent planar motions with respect to the fixed frame up to thrid order and their instantaneous invariants are obtained by using the Lie algebra to the planar motion group near identity element.
