Human Robot Interaction — Quiz

Test your understanding of human robot interaction with 5 practice questions.

Practice Questions

Question 1

Which of the following advanced control strategies is most critical for achieving seamless shared autonomy in complex human-robot collaborative tasks, particularly when human intent is uncertain?

Question 2

Consider a scenario where a collaborative robot is assisting a human in an assembly task. The human's desired trajectory is given by $\vec{P}_H(t) = \begin{pmatrix} 0.5t \\ 0.2t^2 \end{pmatrix}$ and the robot's nominal trajectory is $\vec{P}_R(t) = \begin{pmatrix} 0.4t \\ 0.3t \end{pmatrix}$. If a shared autonomy system aims to minimize the positional error between the human and robot, what is the instantaneous velocity difference vector $\Delta\vec{v}(t)$ between the human and the robot?

Question 3

In the context of designing intuitive human-robot interfaces, which cognitive principle is most effectively leveraged by providing immediate haptic feedback for robot actions?

Question 4

A human operator is controlling a robot arm with a force-feedback joystick. The robot's end-effector applies a force $\vec{F}_R = \begin{pmatrix} 10 \\ 5 \end{pmatrix}$ N, and the human applies a force $\vec{F}_H = \begin{pmatrix} -3 \\ 8 \end{pmatrix}$ N. If the shared autonomy system is designed to achieve a resultant force $\vec{F}_{resultant} = \begin{pmatrix} 8 \\ 15 \end{pmatrix}$ N, what additional force $\vec{F}_{add}$ must the robot apply to reach the target resultant force?

Question 5

In a human-robot interaction system, the human's trust in the robot is modeled by the function $T(t) = 1 - e^{-kt}$, where $t$ is time and $k$ is a constant representing the rate of trust development. If $k=0.5$ and the desired trust level is $0.8$, how long will it take to reach this trust level?
