Autonomous Trunk Jui-Shan Grace Hsu· Andrew Ko · Ken Murray Nathan Ng· Prashant Tatineni· David Yamagata April 27, 2006 ME 102 Group 10 – The Loggers
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
