4. A single joint robotic arm is moving from 0∘ to 90∘ in 5 seconds and is at rest at start and stop. Fit a cubic polynomial and find the third coefficient (a2) corresponding to the term a2t2.
- 10.8
- 1.08
- 108
- 1.8
Answer :- a
5. The practical problem of using a cubic polynomial to represent a trajectory is that
- their is discontinuity in velocity
- acceleration has constant value throughout the motion
- acceleration is zero at start and stop
- acceleration is not zero at start and stop
Answer :- d
6. The basic definition of a sensor and actuator is they
- convert energy from one form to another
- convert position to electric signal
- filters the electric signals
- amplifies the electric signal
Answer :- a
7. The resolution of angular position measurement by an incremental encoder can be increased by using
- two encoders and a NOR gate
- two encoders and a XOR gate
- an encoder and a XOR gate
- an encoder and a NOR gate
Answer :- b
8. A hall effect sensor senses an object by detecting the change in
- capacitance
- eddy current
- inducted EMF
- magnetic lines of force
Answer :- d
9. The force measurement by a force/torque sensor always has some error because
gain matrix is non – square
gain matrix is semi positive definite
gain matrix is singular
of inefficient energy transfer
Answer :- a
10. Although stepper motors can provide large torques they are not normally used in robotics due to their weight. Stepper motors are heavy because they are made of
- paramagnetic materials
- non conductive mnaterials
- semi conductor materials
- ferromagnetic or magnetic materials
Answer :- d
