Today, we continued to work on the conceptual design of the robot.  Some ideas we had:

  • It is necessary for the robot to be relatively narrow (<30″) so that it can fit through a standard doorway.  We do not have any real restrictions on the length and height of the robot, but to keep it relatively manageable, we intend to keep it under 42″ long.
  • If we moved the drive gearboxes from the center wheels to the back wheels, we could potentially move the scuba tanks lower to the ground and make the whole robot more compact.
In addition to working on general conceptual ideas, we started on the CAD design.  Several students worked to begin modeling the robot’s drivebase.  The plan right now is to build a custom chassis specifically for this robot but to integrate some of the drivetrain components that we already have.
