3. Two Robots Sent In Mine conditions too dangerous for rescuers Both were controlled by lengthy and delicate tethers Mine rescue robot
4. But it was too late Second Explosion on November 24 Authorities concluded that no one could have survived
5. Cave Crawler Robotics Institute Sponsor Red Whittaker Chuck Whittaker Aaron Morris Uland Wong “Advanced Reconnaissance Scout” Gas readings, structural map and images Semi-Autonomous Wireless
19. Foci Understand how a remote operator tracks, monitors, and directs a semi-autonomous robot to accomplish a task. Understand what information a mine rescuer needs from the mine and its priority. Understand the physical and environmental limitations placed on a mine rescuer’s ability to use an electronic device.
20. Foci 1) Robot ControlUnderstand how a remote operator tracks, monitors, and directs a semi-autonomous robot to accomplish a task. 2) Sensory Information and Decision MakingUnderstand what information a mine rescuer needs from the mine and its priority. 3) EnvironmentUnderstand the physical and environmental limitations placed on a mine rescuer’s ability to use an electronic device.
29. Consolidation Problem: Tested on different users on every CI - Artifact - Sequence Success: Affinity Diagramming was effective - Got all team members on same page - Enabled team with walk data with client
30. Visioning Problem: limited knowledge of technical limitations -1st session (within team): get ideas out and get familiar with the process - 2nd session (with client): get their ideas and implications for technical constraint
47. Paper Prototype Overcame a complex and dynamic interface with sliding paper widgets and replaceable screens. Paper artisans Nisha, Justine and Tim Completed Paper Prototype
The only cultural implications we say were related to the mechanics and abilities of the robot, which was out of our hands. So, we decided not to model any of our CI’s with the Cultural Model.NOTE TO PRESENTER: DO NOT waste time reading them the contents of this table. Just talk about why we didn’t do cultural, and why we didn’t model Danny or Bruceton.
Our story begins anew
One high-level screenshot of our interface. I will now describe some of the main points in detail.
We chose a tablet with stylus for several reasons: BO station always there, worker may have gloves / mask, and almost always more than one person viewing it.The manual controller contains functions from our consolidated models.
MSHA – Robot Operator asked to perform 3 jobs: Driving, taking notes, relaying notes to command.Mine Comp – Different numbering system between the BO and Command led to a team “blowing up” the mine by moving explosive gas over a glowing battery. A map breakdown led to this.Robot Driver and Command
When interviewing and consolidating, we were searching for what information is important when operating a robot.
Gas Readings are extremely important to mine rescuers. We wanted to make this as clear, easy and understandable as possible. Automatically placed on map. Placard symbol used at the competition.Red coloring for explosive gas mix.
