An 8 bits absolute binary encoder is used to measure the distance traveled by the material in the conveyor. It is connected in the shaft (d=40cm) where the belt rotates. In the initial location of material the encoder reading is 11010110 as the conveyor rotates, the encoder created 2 complete rotation clockwise and end up with the value of 10001101. What is the distance travelled by the material.

Required information A model of a person's arm is used for ergonomics studies. Distances are rAB = 30 cm, BC = 28 cm, and rCD = 19 cm. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. y D C25° 30 Determine the position vector TAD and its magnitude rAD· The position vector TAD 1i)cm and the magnitude rAD is cm.

23. The programmer used three-point method to set up an accurate UF[3] on the part reference surface by sequentially recording points 1, 2, and 3 that are specified on the part reference surface for the three-points method in the robot system. If the programmer recorded three points used by the three-point method in the sequence of points 1, 3, 2 rather than point 1, 2, 3, then (a) the direction of x-axis is not changed (b) the direction of z-axis of UF[3] is changed (c) UF[3] setup is not accurate relative to the part reference surface (d) the origin of UF[3] is changed 24. The programmer preciously recorded all robot points P[n] for a robot task program. However, it is found that during the execution of the robot program, the robot TCP can't always precisely reach to each recorded point. Which of the following statements is correct: (a) The robot has poor accuracy (b) the robot has poor repeatability

Let E, B, and S be respectively the Earth-, body-fixed, and sensor frames. These frames are related through the following rotation vectors: B [ABE]" = (1/3,0, 0) rad [ASB]° = (0,0, T) rad Using the Euler symmetric parameters, compute the rotation vector [ASE]°.
