Autonomous Trunk
The Problem


Items placed in trunks can slide around
and are easily damaged
Basic nets help but are limited


Usually span the middle of the trunk, getting
in the way
Often not the
appropriate size
Autonomous Trunk
Design Objectives



Accommodate objects of different sizes
and fragility
Apply enough force to secure the object
without damaging it
An “out of the way” system that allows for
easy loading and unloading
Autonomous Trunk
Project Design


Net that covers and tightens around the
object
Two settings for different sizes

High tension



Secure heavy items
Prevent from moving and damaging smaller items
Low tension


Autonomous Trunk
Hold light objects in place
Fragile items might otherwise move around and be
damaged by sides of trunk
Components


Net anchored at
three set locations
in the rear of the
trunk
Connected to a
rope that allows for
adjustable
positioning in the
front by motor
Autonomous Trunk
Mechatronic Integration


Encoders are used to
determine when
proper tension has
been reached
Based on speed of
spool rotation and
voltage
Autonomous Trunk
Advantages




Keeps objects secured in a confined area
Flexible enough to handle multiple objects
Relatively inexpensive and lightweight
Allows easy loading and unloading
