16. You are asked to design a mobile robot Items 19–21 refer to the following scenario.
for the fire department capable of
automatically identifying a fire and Mr Brown is an elderly carpenter who was
extinguishing the flames. Which of the recently diagnosed with a back problem. In his
following core sensors should the robot small workshop he works around a 4 ft table
have? where he cuts the wood, and a 2 ft table where he
carves his design in the board. Mr Brown would
I. Temperature sensor like a chair designed to prevent him from
II. Motion sensor standing for long periods around the 4 ft table and
