- Many handicapped individuals struggle using electric wheelchairs. Researchers used Bayes' rule to assess a “intelligent” robotic controller that attempts to record a wheelchair user's intent and assist in navigation. Consider the situation below. A wheelchair user may either (1) turn abruptly left and approach a door, (2) go straight to the opposite side of the room, or (3) turn slightly right and halt at a table. D (for door), S (straight), and T (for time) (for table). P(D) = 0.4, P(S) = 0.25, and P(T) = 0.35. The wheelchair has a joystick operated by a robot. The user directs the joystick straight 50% of the time while going through the door, 30% of the time when going straight, and 25% of the time when going to the table. What is her most likely destination, calculate based on P(D|J), P(S|J) and P(T|J)?arrow_forwardAfter a ball rolls off the edge of a horizontal table at time t = 0, its velocity as a function of time is given by v=1.2i9.8tj where v is in meters per second and t is in seconds. The balls displacement away from the edge of the table, during the time interval of 0.380 s for which the ball is in flight, is given by r=00.3803vdt To perform the integral, you can use the calculus theorem [A+Bf(x)]dx=Adx+Bf(x)dx You can think of the units and unit vectors as constants, represented by A and B.
