Presentation Transcript

  1. Layout Drawings Presentation ME 4182 Team: 5 Guys Engineering + 1 Nathan Bessette, Rahul Bhatia, Andrew Cass, Zeeshan Saiyed, Glen Stewart YJ Chok

  2. Automatic Whiteboard Wiper • Last Time • Post Midterm Review Presentation • Reviewed comments on midterm presentation and responded • This Time • Layout Drawings • Layout or assembly drawings • How individual parts or subsystems fit together as a whole • Encouraged to use computer modeling software • Drawings for actual design, not prototype

  3. Front View • Uses 5 pulleys • Entire system uses 2 motors • Rack & pinion system utilized for eraser

  4. Side View • Very slim profile • Rack and pinion allows vertical movement of eraser • Does not take up much space above and below whiteboard

  5. Rack & Pinion Subsystem • Utilizes rack & pinion system coupled with electric motor to move eraser up and down • Wheels at top and bottom slide along top and bottom rails placed near whiteboard

  6. Main Motor Drive Subsystem • Motor combined with cable system provides movement for arm frame • Controller and power systems combined in one enclosure

  7. Pulley Details • 3 pulleys have 2 slots for cables • Rotates in clockwise direction to move arm left, counter clockwise to move arm right • Heavy duty axel and mount for prolonged durability, aluminum material to reduce weight

  8. Roller Details • Wheels grip onto guide rail to allow movement while providing stability to eraser frame

  9. Automatic Whiteboard Wiper • Next Time • Engineering Analysis • Determine areas most likely to fail first and show they have been designed properly • Factor of safety • Engineering/ manufacturing problems • Estimate basic features • Address following areas • Power consumption • Strength of materials analysis for fasteners and critical load bearing elements • Fatigue analysis for critical load bearing elements • Stability during operation • Kinematic analysis • Dynamic load analysis • Control methods and algorithms • Material selection • Safety; Human interface • Tolerances • Performance analysis and prediction
