Webots Robots Catalog

Webots Robots Catalog

Use this skill to quickly select pre-built robot and vehicle models from the Webots PROTO library.

Scope

• Focus on cataloging available robot models, PROTO names, and practical starting points.
• Use references/robots_reference.md for detailed device-name maps and high-frequency robot details.
• Exclude custom robot authoring workflows.
• Exclude low-level sensor and actuator API tutorials.

Other Notable Robots

• Aibo ERS7 (Sony dog robot)
• Spot (Boston Dynamics quadruped)
• Salamander (amphibious)
• Blimp (lighter-than-air)
• Sojourner (Mars rover)
• PR2 (Willow Garage)
• Shrimp (climbing rover)

Example: Using an E-puck

# The E-puck has these device names:
# Motors: "left wheel motor", "right wheel motor"
# Distance sensors: "ps0" through "ps7"
# LEDs: "led0" through "led9"
# Camera: "camera"
# Accelerometer: "accelerometer"

from controller import Robot
robot = Robot()
timestep = int(robot.getBasicTimeStep())

# Get motors
left = robot.getDevice("left wheel motor")
right = robot.getDevice("right wheel motor")
left.setPosition(float('inf'))
right.setPosition(float('inf'))

# Get distance sensors
sensors = []
for i in range(8):
    s = robot.getDevice(f"ps{i}")
    s.enable(timestep)
    sensors.append(s)

while robot.step(timestep) != -1:
    values = [s.getValue() for s in sensors]
    # Simple obstacle avoidance
    if values[0] > 80 or values[7] > 80:
        left.setVelocity(-2.0)
        right.setVelocity(2.0)
    else:
        left.setVelocity(6.28)
        right.setVelocity(6.28)

Usage Pattern

• Identify robot class first: mobile, manipulator, humanoid, drone, or vehicle.
• Select PROTO by model requirements (DOF, locomotion, payload, sensor suite).
• Add robot via PROTO tree and confirm device names from references/robots_reference.md.
• Implement controller logic using exact device identifiers.
