Question

Which of the following terms are related to active compliance provided in a robot to correct lateral and angular errors? A. Controller
B. Remote Centre Compliance
C. Software
D. Sensors

• A. A, B and C only
• B. B, C and D only
• C. C, D and A only
• D. A, B and D only

Hint:

Active compliance = Sensors + Controller + Software; Passive = RCC.

Answer 1

The Correct Option is C

Concept: Compliance in robotics refers to the ability of a robot to accommodate positional errors during assembly or interaction. There are two types:
• Passive compliance → mechanical devices (e.g., RCC)
• Active compliance → achieved using sensing, control, and software

Step 1: Understanding Active Compliance.
Active compliance involves:
• Sensors → detect errors (force, position)
• Controller → processes feedback and generates corrective action
• Software → implements control algorithms

Step 2: Evaluate option A (Controller).
Controller:
• Essential for processing feedback signals
• Adjusts motion dynamically Hence, A is correct.

Step 3: Evaluate option B (Remote Centre Compliance).
RCC:
• Mechanical passive device
• Works without sensors or control Thus belongs to passive compliance → not active.
Hence B is incorrect.

Step 4: Evaluate option C (Software).
Software:
• Implements algorithms for correction
• Controls motion based on feedback Hence C is correct.

Step 5: Evaluate option D (Sensors).
Sensors:
• Detect misalignment, force, or position error Essential for active compliance → correct.

Step 6: Final conclusion.
Correct components: \[ A, C, D \] \[ \boxed{\text{Answer: C, D and A only}} \]
