Urban Search and RescueCheckpoint Feedback

Carnegie Mellon University

16-311 Introduction to Robotics

March 29th 2006


Checkpoint performance

Checkpoint Performance

  • 5 of 7 teams finished the checkpoint

  • Average:75

  • Median:95

  • Mode:100

  • Final Competition Tuesday April 4

  • Preparation

    • Checkpoint Feedback

    • Presentation of Final Competition.


Checkpoint

Checkpoint

  • General Observations from Checkpoints

    • Incline

      • Nearly everyone was able to complete this obstacle.

    • Bumps

      • Nearly everyone was able to complete this obstacle.

    • Stairs

      • Many teams had difficulty, it is highly recommended this issue be resolved.

    • Rubble

      • Nearly everyone was able to complete this obstacle.

    • Narrow Corridor

      • Nearly everyone was able to complete this obstacle.

    • Low Light

      • No teams attempted this obstacle, highly recommend practice.


Difficulties

Difficulties

  • Low ground clearance

    • Robots getting hung up on rubble and bumps.

  • Center of gravity

    • Robots begin to climb stairs and inclines only to flip over.

  • High torque wheels/treads

    • Torque is good but so is speed.

  • Size constraints

    • If your robot changes dimension be sure you can still fit through narrow corridors.

  • Fragile Designs

    • If you lose any part of your robot during the competition your run is over.

    • Grinding and/or clicking noises are never a good thing.

    • Two words: Drop Test

  • Controllability Issues

    • Low level controls make it difficult to precisely traverse the environment.


What did work

What Did Work

  • Added weights

    • Washers, Pennies, Pad Lock?

    • Change the location of your center of mass

  • Reinforced Robots

    • Zip ties are your friend

    • Twist ties and wires

  • Camera

    • Pan and tilt camera heads are great

    • Zip tying the camera to your robot

    • Visual marker to keep your frame of reference


Advice

Advice

  • Try to drive without looking at the robot.

  • Don’t underestimate the value of sensors to eliminate blind spots.

  • Be conscious of size and speed of the robot.

  • The world will get worn down – be prepared for it.

  • Clicking, whining is a bad sign.


This just in

This just in…….

  • Hurricane has hit a remote site

    (Scaife Hall)

  • Rescue teams will be:

    • arriving onsite Monday April 3rd

    • commencing operations Tuesday April 4th.


Victims

Victims

  • These individuals have been identified as being in the building at the time of eruption:

    • Howie

    • Geist

    • Avi

    • Linda

    • Brandon Boyd

    • Dakota Fanning

    • President Bush

    • Johnny Depp


Satellite images

Satellite Images

  • These images of the disaster area have been gathered from satellite information:

    • Zone 1

      • Stability: High

    • Zone 2

      • Stability: High-Medium

    • Zone 3

      • Stability: Low

    • Zone 4

      • Stability: Low-Medium

    • Zone 5

      • Stability: Low-Medium

Goal

  • Your mission is to send your robots into these areas and using teleoperation to guide them through each zone identifying individuals and clearing zones.


Scoring

Scoring

  • Victims found in each zone are worth 7 points each.

  • An additional 5 points will be awarded if the team can determine who the victim is (pictures will be provided).

  • When a group is done with a zone, they have the opportunity to say whether they have cleared it or not. “Cleared” means they have found all victims in that zone. If a group claims they have found all victims, and they are right, they earn 5 points. If a group claims they have found all victims, and they are wrong, they lose 5 points. No points are awarded for a group “knowing” that they have not found all victims in a zone.

  • Zone 5 is the upper level of the world.


Demo times

Demo Times

  • The demos will be held on Tuesday April 4th in the REL

  • Each team is allotted a total of fifteen minutes for their demo

    • Five minutes for set up

    • Ten minutes to search for victims

  • A sign up sheet will be available immediately following this presentation at the front desk.

  • Random lottery will determine order.
