The Autonomous Trunk System addresses the common issue of items sliding around in vehicle trunks, leading to potential damage. This innovative design accommodates various object sizes and fragility levels while securely holding them with adjustable tension nets. Featuring a three-location anchoring system and motorized positioning for easy access, it utilizes encoders for precise tension control. The solution is flexible, affordable, and lightweight, ensuring safe and efficient loading and unloading of a wide range of items without compromising their integrity.

Introduction • The Problem • Objectives • Project Design • Components • Mechatronic Integration • Advantages
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
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
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 • 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
Mechatronic Integration • Encoders are used to determine when proper tension has been reached • Based on speed of spool rotation and voltage
Advantages • Keeps objects secured in a confined area • Flexible enough to handle multiple objects • Relatively inexpensive and lightweight • Allows easy loading and unloading
