Claim Text:
1. A prediction system comprising: an acquisition device configured to acquire a value of electric resistance of a cable secured by fixing members to a pair of link members configured to rotate relative to each other through a joint; an execution device configured to cause the joint to execute a predetermined operation; and a prediction device configured to predict a service life of the cable based on a change in the value of electric resistance acquired by the acquisition device while the execution device is causing the joint to execute the predetermined operation, wherein when the predetermined operation is changed, the prediction device is configured to predict a new service life based on a new predetermined operation after the change, configured to calculate an elapse of time based on an execution history of the predetermined operation before the change, configured to subtract the elapse of time from the new service life, and configured to set a resulting difference value as a predicted value.
