Original Project Objectives
• The ShelfStocker will be a robot that
reads in a bar code label and then stocks
the item in a particular location based on
that label.
• Automates a lot of shipping and receiving
work in a general way.
• Can be scaled to any size product using
different bodies.

Problems Encountered
• Mechanical
– How to pick up an item
– How to steer
• Event Handling
– DataEvent functionality was not implemented
Problems Encountered (2)
• Scanner
– Mechanical limitations
– Serial port issues
– Voltage levels
• Navagation

– How to go straight
Final Project Results
• Success!
What We’d Do Different
• Get help from a mechanical engineer
• Don’t ever unhook the JStamp from the
ShelfStocker
• Get a better bar code scanner sooner
• Use super glue
