Master Task List
High Priority
- Design layout for Electrical components (where side car, jaguars, etc, goes).
- Come to agreement with mechanical on layout/placement
- Position sensors '('and sensor flags) in inventor model
- Collaborate with mechanical on the position and mounting of these sensors (need to know range of motion for mechanical actuators)
- Should think about how big the flags have to be
- Should think about how we couple together potentiometers, encoders, etc
Medium Priority
- Homebrew sensor layout
- Homebrew sensor construction
- Once electrical layout & position/robot complete in inventor we can rough out wire lengths
- Custom I/O board (for pullups, current limiting resistors, signal light drivers, etc).
Low Priority
- Design/Build LED/Light driver board
- Inventory current items

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.
