I know that a redundant link is a link that doesn't affect the motion of the mechanism even if it is removed . But how could we recognize these links ?
I was solving a problem abuout finding the mobility of a mechanism. I have noticed that the mechanism is negative , although the configuration of the mechanism appears as if the mechanism is able to move , so this is a contradiction. Is this method used to investigate if there are redundant links ? (By finding the mobility first and checking whether the mechanism is able to move or not )
After this step , I think we must recalculate the true mobility , by first removing the redundant links . How could we determine these links ? Is there a certain method ? or I must check all the links , by imagining what will happen to the motion of the mechanism if each link was removed ?
