  Mobility, which is a basic property for a mechanism has to be analyzed to
find the degrees of freedom. A quick method for calculation of degrees of
freedom in a mechanism is proposed in this work. The mechanism is represented
in a way that resembles a zebra crossing. An algorithm is proposed which is
used to determine the mobility from the zebra crossing diagram. This algorithm
takes into account the number of patches between the black patches, the number
of joints attached to the fixed link and the number of loops in the mechanism.
A number of cases have been discussed which fail to give the desired results
using the widely used classical Kutzbach-Grubler formula.
