Various shapes of TrashCans in UC Berkeley Campus

Several Boxes look like flocking.

what would move? trash boxes and cleanerswhy? to clean up UC Berkeley campus

How should it feel? dynamic flock like “boid” simulation

How should it feel? People wants to going into the flock of cleaning boids and interact with them.

Flocking TrashCan Robot

• With Only 3 rules, dynamic behavior emerges.

• Separation: steer to avoid crowding local flockmates

• Alignment: steer towards the average heading of local flockmates

• Cohesion: steer to move toward the average position of local flockmates

Flocking TrashCan Robot

• Team of TrashBox robots and Cleaner robots

• one flock? or two flocks?

• ratio? : 50:50? 30:70? 70:30?

• Interaction with People

• going away from people?

• coming near to people?

• what is good balance?

Flocking TrashCan Robot

• Adding only one rule brings dynamic behavior of stopping at a person and backing to the flock.

• Just changing flocking parameters brings the balance.

• dynamic movement of “boid” flocking

• Human2Robot

• adding only one rule

• the body works not only as a trash box but also as a cylinder display for Processing.
