Why must the robot and conveyor be homed before operation?

Joint motion differs from linear motion because it:

Consider a system in which 4 feeder lines feed a final assembly workstation. The assembly station can only start processing once all the feeder lines have completed their task. Processing times for the feeder lines and the assembly station are random with the same coefficient of variation. Suppose that the total work content to produce a unit is 1 hour and you are free to allocate the work any way you want among the assembly workstation and the 4 feeder lines, as long as the sum of work equals 1 hour. To maximize productivity, should the assembly station have an average work content of (a) 12 minutes, (b) more than 12 minutes, or (c) less than 12 minutes?

Consider the set of 6 jobs with processing times (21.4, 5.7, 16.2, 8.4, 9.0, 11.2) waiting to be processed on a single machine.  (a) (7 points) Determine the sequence of jobs that minimizes the average number of jobs at the machine. Sequence = ([seq]) (b) (5 points) Calculate the average number of jobs at the machine. Round to 1 decimal place. Average number of jobs = [jobs]

Consider a system of 10 components in series. What reliability must each component have to produce an overall system reliability of 0.75? Round answer to 3 decimal places.
