Structure of presentation
Structure of Presentation

  • Outline of tasks

  • Introduction of team members

  • Sensors & Actuators

  • Initial Ideas

  • Testing

  • Development & Adaptation


Tasks
Tasks

  • Cans need to be removed from an arena

  • Cans need to be removed from an arena whilst navigating around obstacles

  • Hunt a prey robot and avoid a predator robot


Team roles

Alex - Structure and design testing

James - Programming and Sensors

Michael - Programming and Testing

Sam - Design and Construction

Team Roles


Sensors and actuators
Sensors and Actuators

  • 1x Touch Sensor (bumper)

  • 1x Light Sensor (boundary detection)

  • 2x Motors (movement)


Initial ideas
Initial Ideas

  • Front & rear bumper

  • Light sensor to detect can

  • 6 wheels connected with gears

  • Slow but high torque & traction


Testing
Testing

  • Tested boundary awareness

  • Sensitivity of bumper to differentiate between cans/obstacles/robots

  • Gearing & sizes of wheels

  • Field of view of IR emitter/receiver


Development
Development

  • Blocked off IR receiver to limit FoV

  • Front bumper for objects & cans

  • Vertical light sensor to detect boundary

  • 4 wheels connected with gears

  • Small and compact chassis


Program
Program

  • All objectives in one small program

  • Initial setup

  • Sensor readings & logical comparisons

  • Variable display



Evaluation
Evaluation

  • The project has gone well overall

  • The objectives were completed

  • Some small problems occurred during development

  • Our ideas were on the whole fairly good ones

  • We tried to use simple solutions where possible
