Description of motion of a mobile robot...

form of description of the system with non-holonomic constraint imposed on motion. If we assume that q2 = [/?, a]T, system of eąuations (1.10) can be written in the form

1TI4I2[P sin /3 + (P)1 cos P] + (2mi + m^)r[ót cos PaP sin P\ = X\ m^l—PcosP + (P)1 sin/?] + (2mi + m^rfdsinP + d/?cosP\ = A2

(1.11)

(2m\l1 + 7724/2 + 1z4 + 2/xi + 2Iz\h\)p - m^rap =

= (Mi -M2- Ni fi + JV2/2)hi[(2mi + m4)r1 + 2 IzX\a + mil2r(ff)1 =

= M\ + M2 — N\ fi ^2/2

In eąuations (1.11), the right-hand sides are decoupled - such form of eąuations facilitates their solution. In the case of analysis of dynamical converse problem (1.11), they allow for determination of driving torąues a well as Lagrange’s multipliers. In the case of analysis of the direct problem, the solution to these eąuations will allow for determination of kinematic parameters of the analysed model.


where s stands for the number of independent parameters of the system expressed in generalized coordinates qj (j — 1,..., n), the number of which corresponds to the number of the system degrees of freedom. Ali generalized velocities are in this case given by

Qj = Cijći + Gj    (2.2)

i— 1

The variables e; are called the characteristics or kinetic parameters of the system defined in the generalized coordinates. The right-hand sides of eąuations

Maggie’s dynamical eąuations of motion

Motion of non-holonomic systems can be described with the use of ano-ther mathematical formalism, e.g. Maggie’s eąuations (Gutowski, 1971). These eąuations, describing motion of systems in terms of generalized coordinates, are determined in the form
