Enhanced Mounted Crane
Pros and Cons
MANUAL CRANE CONTROL
Operator is mainly near it (wired). Cranes are moved at low speed.

Enhanced Mounted Crane
You’re not like every one
Proposed ENHANCEMENT
ADDING PID TO AXIS MOTION
reducing position and speed control
And hence cutting down transportation delay
ADDING GESTURE CAPABILITIESBY ADDING MACHINE VISION TECHNOLOGY TO UTILIZE
OPERATOR GESTURES FOR MOVING CRANES EVEN WHEN
NOT IN SAME LOCATION
