What is robotics kinematics primarily concerned with?

• robotic control systems

• motion and position of robots

• sensors used in robotics

• programming languages used in robotics

In robotics, what is meant by the "end effector"?

• A sensor that detects obstacles in the robot's path

• A software program that controls the robot's movements

• A device used to control the robotic arm

• Device or tool attached to the end of a robotic arm or manipulator

Forward kinematics in robotics is used to:

• Determine the position and orientation of the end effector based on the joint angles and lengths of the robot's links.

• Control the robot's gripper to pick up objects.

• Determine the speed and acceleration of the robot's end effector.

• Calculate the joint angles and lengths of the robot's links based on the position and orientation of the end effector.

What does the term "joint space" refer to in robotics?

• Set of all possible positions that a robot's joints can take

• The space where robots are stored

• The space between two robots

• The space where robots are assembled

Inverse kinematics in robotics is used to:

• Control the motion of a robot based on sensory feedback.

• Calculate the forward kinematics of a robot.

• Determine the position and orientation of the end effector given joint angles.

• Determine joint angles for a desired end effector position and orientation.

Which of the following is an important aspect of positional analysis in robotics?

• Determining the position and orientation of objects

• Calculating the speed of the robot

• Identifying the color of objects

• Analyzing the weight of objects

In robotics, the term "workspace" refers to:

• The place where a robot is stored.

• The area in which a robot can operate or move.

• The power source of a robot.

• The programming language used in robotics.

Which type of joint is often used in robotic arms to provide flexibility and maneuverability?

• Spherical joint

• Prismatic (linear) joint

• Revolute (rotational) joint

• Fixed joint

What is the term for the study of how robots can move safely in their environment, avoiding obstacles?

• robotics avoidance

• robotics path planning

• robotics obstacle detection

• robotics navigation

When studying positional analysis in robotics, what does the term "singularity" refer to?

• A configuration where the robot's end effector loses one or more degrees of freedom.

• A configuration where the robot's end effector becomes more stable.

• A configuration where the robot's end effector becomes more flexible.

• A configuration where the robot's end effector gains additional degrees of freedom.
