Human-Robot Team Interaction Through Wearable Haptics for Cooperative Manipulation

Area of Science:

• Robotics
• Human-Computer Interaction
• Control Systems

Background:

• Teleoperation enables humans to perform tasks in remote or hazardous environments using robotic systems.
• Cooperative tasks involving human-robot teams, especially with large or heavy objects, present control challenges due to differing degrees of freedom.
• Asymmetry in control, where robots have more controllable degrees of freedom than human operators, is a key challenge in human-robot interaction.

Purpose of the Study:

• To propose and evaluate a control scheme for human-robot team interaction in teleoperation, addressing control asymmetry.
• To assess the suitability of wearable haptic fingertip devices for multi-contact teleoperation tasks.
• To determine if the proposed control approach and haptic devices enhance cooperative manipulation.

Main Methods:

• A novel control scheme was developed to reduce the dimensionality of the interaction space, accommodating limited human command and feedback signals.
• Wearable haptic fingertip devices were utilized to provide feedback and enable multi-contact interaction during teleoperation.
• A user study was conducted to evaluate the effectiveness of the proposed control approach and haptic devices in cooperative manipulation tasks.

Main Results:

• The proposed control scheme effectively manages the asymmetry between human operators and robot teams in teleoperation.
• Wearable haptic fingertip devices proved suitable for multi-contact teleoperation, providing valuable assistance.
• User study results indicated that the control approach and haptic devices are appropriate for human-robot team interaction in cooperative manipulation.

Conclusions:

• The developed control scheme is effective for human-robot team interaction in teleoperation, particularly for cooperative tasks.
• Wearable haptic fingertip devices offer significant assistance in cooperative manipulation, enhancing the capabilities of human operators in telepresence.
• This research advances the field of human-robot collaboration by providing a practical solution for controlling complex robotic systems with human operators.
