        Deploy the Robotic Arm. 

      The  robotic arm will be needed at the waste dump-site  for 
sampling  barrels  of nuclear waste. Due to the amount  of  power 
consumed by the arm, it is necessary to turn off some instruments 
in  the sub and the outside light if it is on. This will be  done 
for  you and the instruments will automatically return after  the 
arm has retracted, but the outside light may have to be  recycled 
to get it on again.
