How does inverse kinematics differ from forward kinematics in robotics?
  • A. Inverse computes joint angles from end position; forward does opposite
  • B. Inverse encrypts control data; forward decrypts it
  • C. Inverse is used for wheels; forward for arms
  • D. They are the same
Correct Answer: A
Explanation:
Inverse kinematics calculates joint parameters for a given end-effector pose; forward kinematics computes end pose from joint angles.

What is the purpose of inverse kinematics in a robotic arm?
  • A. To compute the joint movements needed for a desired end-effector position
  • B. To encrypt robot control signals
  • C. To linearize sensor inputs
  • D. To measure force and torque
Correct Answer: A
Explanation:
Inverse kinematics calculates how to move joints so the robot's end-effector reaches the target position.

What is a characteristic of soft robotics?
  • A. Use of rigid steel frames
  • B. Built from flexible materials allowing safe interaction
  • C. Operate only underwater
  • D. No sensors
Correct Answer: B
Explanation:
Soft robots use pliable materials and can adapt their shape for safer human interaction.

What does the term 'manipulator' refer to in robotics?
  • A. A software robot
  • B. A robotic arm or mechanism for moving objects
  • C. A sensor type
  • D. An algorithm
Correct Answer: B
Explanation:
A manipulator is the robot arm or mechanical unit used to move and manipulate objects.

What is the Denavit-Hartenberg (DH) convention used for in robotics?
  • A. Standardizing robot kinematic parameters for link transformations
  • B. Encrypting robot control signals
  • C. Actuator design
  • D. Mapping workspace coordinates
Correct Answer: A

The DH convention is a standardized method for assigning coordinate frames to robot links for kinematic analysis.
Related Question 5
How does edge computing differ from cloud computing?
  • A. Edge computing processes data close to the source, reducing latency
  • B. Edge computing requires no security measures
  • C. Edge computing is only for mobile devices
  • D. Edge computing uses infinite storage
Correct Answer: A
Explanation:
Edge computing processes data close to the source (at the network edge), which reduces latency compared to sending everything to the cloud.
