Robot platform 0-1000mm range 135° sensor view Example object I The task will involve investigation, selection and evaluation of suitable sensors and development of a processor-based measurement and display system which could be used for obstacle detection/avoidance. Your system must measure and display the sensor information and indicate: if an object has been detected, the location within the 135-degree field of view the distance from the robot.

A differential equation encountered in the vibration of beams is d4ydx4=2D where x = distance measured along the beam; [x]=[L] y = displacement of the beam; [y]=[L] = circular frequency of vibration; []=[T1] = mass of the beam per unit length; []=[ML1] D = bending rigidity of beam; [D]=[FL2] Show that the equation is dimensionally homogeneous. Note that [F]=[MLT2] see Eq. (1.21:).

A(n) ________ displays a magnified image of a part on a screen for conducting measurement.

Using the information in Problem 1.22, estimate the ambient air temperature that could cause frostbite on a calm day on the ski slopes. 1.22 In order to prevent frostbite to skiers on chair lifts, the weather report at most ski areas gives both an air temperature and the wind-chill temperature. The air temperature is measured with a thermometer that is not affected by the wind. However, the rate of heat loss from the skier increases with wind velocity, and the wind-chill temperature is the temperature that would result in the same rate of heat loss in still air as occurs at the measured air temperature with the existing wind. Suppose that the inner temperature of a 3-mm-thick layer of skin with a thermal conductivity of 0.35W/mKis35C and the air temperature is 20C. Under calm ambient conditions the heat transfer coefficient at the outer skin surface is about 20W/m2K (see Table 1.4), but in a 40-mph wind it increases to 75W/m2K. If frostbite occurs when the skin temperature drops to about 10C, do you advise the skier to wear a face mask? What is the skin temperature drop due to the wind?

Describe the two basic types of passenger weight detection sensors used in most vehicles.

The line type used to show edges of an object that can be seen in a particular view is called a(n)______ or_______ line.

What does an X-bar chart track?

What is an MCU and what is its function?

Which of the following statements about zirconium oxygen sensors is not true? The normal operating range for an O2S is between 0 and 1 volt. If the sensors voltage toggles between 0 volts and 500 millivolts, it is operating normally. The voltage signal from an upstream O2S should have seven cross counts within 5 seconds with the engine running without a load at 2,500 rpm. Engine control systems monitor the activity of the O2S and store a code when the sensors output is not within the desired range.

What electronic component is often used to prevent large voltage spikes from being produced when the current flow through an inductor is suddenly terminated?
