Robot Electromechanical Design Features

DRIVETRAIN

six wheel drive
two CIM motors (maybe 4), 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
wing actuator - motor or pneumatic???

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
one motor for turret rotation
a sensor for turrent position probably not necessary since it's kind of obvious (?)

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.

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.
