Advanced Robotics Week 8 NPTEL Assignment Answers 2025
1. A stepper motor is normally not very accurate as it is operated in
- closed loop
- uncertain environment only
- open loop
- variable loading conditions only
Answer :- c
2. The main difference between a brush type DC motor and a Brushless DC motor is that
- rotor of a brush type DC motor is made of thin magnets
- rotor of a Brushless DC motor is made of thin magnets
- a brush type DC motor implements commutation through a software
- Brushless DC motor has mechanical commutator
Answer :- b
3. A disadvantage of a brush type DC motor is that
- its rotor is light and hence difficult to control
- there are permanent magnets in the rotor which is difficult to manufacture
- it is slightly more expensive as compared to Brushless DC motor
- its brushes wear out
Answer :- d

Answer :- d
9. When a robot picks up or drops an object, the change/effect in the link inertia is minimal because
- it is multiplied by square of gear ratio
- it is divided by gear ratio
- it is divided by square of gear ratio
- it is multiplied by gear ratio
Answer :- c
10. If a system is asymptotically stable and it is subjected to disturbance then
- it will return to the origin
- it will move around the origin in repetitive cycles
- it will stay at its initial condition
- it will move away from the origin in the direction of disturbance
Answer :- a
