Tasks Completed:

• Discussed the pros and cons of mounting positions--transmission/chassis or hopper

Pros on Chassis --> (Over CIM motors)

• Better protection
• Less pain!!!
• More secure

Cons on all Chassis

• 3" marker limit - which makes our first design fail.
• Difficult access
• Less clearance and more cramming
• Difficult wiring
• Larger chance of shorts

Pros on Mounting on Hopper

• Lots of space
• Small chance of shorts because of space
• 
  

Cons for Mounting on Hopper

• Weight concerning large guage wire
• If mounted on lexan, unstable
• If tipped, electronics could get damaged
  

Height of CRio

• Need 6.5" minimum - 8" maximum Data cable from CRio Digital Side car
  

Sensors at Top of conveyor and bottom of conveyor

Currently have 1

Banners are functional - Can be used.

To do - Investigate OMRONs (Order from Digikey?  16.81 in onsies) - 11mm sensing distance - Is this good enough?

Detectable distance (See Note.) 11 ¦ 2 mm (Black paper and OHP paper) 11 ¦ 8 mm (White paper)
Non-detectable distance (See Note.) 20 mm (Black sponge) 45 mm (White paper)

Helpful Links to Sensor pages, ect.

Digikey Omron Reflective Sensor

Above Sensors PDF info

Talked about photoreflective vs. Photo "beam break" sensors

How a reflective Sensor functions

Tasks In Progress:

• Process on choosing mount locations-- Chassis or Hopper
  

---

Tasks to Complete:

• Talk to Mechanical 1/2 for status on Chassis, do we still have a 3" limit? WE NEED DIMENSIONS.
  
• Aquire transmission dimensions
• Hybrid design..? Some on Chassis and some on Hopper?
