Interior-point methods require strictly feasible points as starting points. In theory‚ this requirement does not seem to be particularly restrictive‚ but it can be costly in computation. To overcome

Fig. 4.13: The Robert’s Mechanism Robert‘s linkage is another four-bar approximate straight line generator mechanism with coupler point C. Good results can be obtained with construction parameters d = 1‚ b = 0.538 ‚ a = c = 0.530 e = f = 1.04. Robert‘s mechanism generates a curve which has a linear part parallel to the base link. Links and coupler curve are symmetric.[20] The limitation of this mechanism is that the straight line path is very short. So whole wall cannot be covered while painting
