These fiber optics use a red light that senses if the light stream is broken which is then sent back to the sensor. The range of the the sensor is 6in but a not optimal voltage (10V {<-- Used} but max was 30V) was used. Obtained for free by a mentor.

Robot Electromechanical Design Features 


DRIVETRAIN

  • six wheel drive
  • four CIM motors, one per side on speed controllers

 

BRIDGE MANIPULATOR

  • bridge manipulator is the same as the guide wings of the ball collector


 

BALL ACQUISITION

  • guide wings plus input roller (beater bar)
  • one motor for roller - reversible and on speed controller?


BALL STORAGE

  • three-stage conveyor system
  • one motor for each conveyor segment (3 total), each on speed controller?
  • four beam-break sensors - one at each conveyor exit "parking" position and one at first conveyor entrance to stop input roller.

 

SHOOTER 

  • two-wheel "pinch roller" shooter on rotating turret
  • two motors for shooter (one for each wheel) so that relative speeds can be varied for backspin.
  • an RPM sensor on each motor so that speeds can be matched, or purposely mismatched a known amount of backspin
  • one motor for turret rotation
  • a sensor for turrent position and flag sensors for endstops

IR Sensors

IR (infared) sensors are phototransistors that are used in conjunction with infareddiodes. They are cheap and can be made with parts that we already have.

Progress Report: A proto-type of the sensor has been soulder to a protoboard. A better design and layout out the sensor will come in the future pending the testing of the current protoboard.

Mounting created for IR semsor (2"x1"x1" aprox.). There are three holes: two for mounting one for the phototransistor to stick out.


Test Leads 

About half a dozen teast leads were made some ends with clips and others with banana jacks. They can be used to test electrical circuits.

Mini Beam Sensors

These fiber optics use a red light that senses if the light stream is broken which is then sent back to the sensor. The range of the the sensor is 6in but a not optimal voltage (10V {<-- Used} but max was 30V) was used. Obtained for free by a mentor.
