In order to reduce the harm to workers in handling chemical raw materials, a logistics company introduced robots. A robot can carry $420kg$ more per hour than a worker. The time it takes for a robot to carry $900kg$ is equal to the time it takes for $10$ workers to carry $600kg$.  
$(1)$ Find out how much chemical raw materials one robot and one worker can carry per hour respectively.  
$(2)$ Now, $3600kg$ of chemical raw materials need to be transported. If three robots are involved in the transportation, how many additional workers need to be arranged to complete the transportation within $2$ hours at least?
