Speak-and-Retreat Interaction
A proven interaction pattern for guide robots that balances information delivery with visitor autonomy:
This pattern avoids forcing visitors into conversations while still providing rich information.
Guide Robot System Architecture
Key modules that enable autonomous museum guide behavior:
Why Some Prefer Robot Guides
Obligation-free
"I may or may not listen. It depends on how well the robot is explaining."
Consistent quality
"Robots don't get tired, so explanations won't become rough."
Steady pacing
"It speaks at the same pace, unlike a person who sometimes speaks too fast."
Relation-Building Behaviors
Repeat visitors felt significantly closer to the robot after their second visit (IOS scale: 4.88 → 5.47, p < 0.001):
"When ASIMO said my name and approached me, I was flattered and surprised, yet happy."
Human Guide vs Robot Guide: Visitor Preferences
Based on 231 visitor interviews
"A person can explain how to do something. A robot can do the same, and it can continue its explanation until I understand."

Design Principles for Museum Guide Robots
Approach When Attention is Detected
If a visitor is paying attention to an exhibit, they're likely interested. The robot should approach to give an explanation, just as human guides do. Use position and body orientation to estimate attention targets.
Position for Optimal Explanations
When explaining parts of an exhibit, the robot must take a position where both robot and visitor can see the target. Use F-formation concepts and define explainable regions for each exhibit part.
Track Interaction History
Never repeat an explanation already given. Build on previous explanations for deeper understanding—start with overview, then add technical details for visitors who show continued interest.
Build Relationships with Repeaters
Treat repeat visitors differently from first-timers. Use faster approach, closer positioning, self-disclosure, and compliments. Acknowledging the relationship significantly increases visitor satisfaction.

Control Approaches for Physical Cooperation
When humanoids physically interact with humans, they need specialized control strategies that balance task execution with human safety and comfort.
Impedance Control
Makes the robot behave like a mass-spring-damper system, allowing compliant interaction with external forces.
Admittance Control
Converts measured force into reference velocities, enabling robots to respond to human guidance.
Whole-Body QP Control
Formulates control as a Quadratic Program, optimizing multiple objectives (balance, manipulation, posture) simultaneously.
Human-Aware Control
Extends controllers to include human state, dynamics, and predictions to plan ergonomically optimized collaborative motions.
Reactive vs Proactive Strategies
Robot estimates human reference task online and reacts accordingly. Highly dependent on sensor quality. Good for following human lead.
Robot predicts long-term human task belief and plans ahead. Can reduce human effort and improve comfort. Used when robot has knowledge of optimal trajectories.
