Team Foliarrrr Conceptual Design

Problem Statement Collect samples from the third whorl of the tree, which is generally 8-10 ft. from the top of the tree using a portable device that is easily operated. The normal operating heights are in the range of 75-85 feet and can reach heights of 120 feet. The baseline for our machine to beat is 45 minutes, which is the time it takes to climb and retrieve one sample currently.

Time line of tasks Project Learning Conceptual Design Researched as many ideas as possible for For Reaching And Grabbing/Cutting Compiled it all onto boards Conceptual Design Simple modeled some of our ideas like the boom Functionally broke down the problem further Narrowed down our focus to just four concepts Conceptually worked out how each would work

Conceptual Reaching Designs Trailer With A Telescoping Boom Mechanically Driven Feller Buncher Mechanically Driven/Human Driven Power Ascender Human Driven Mark

Trailer/Boom Mark doesn’t climb the tree Boom sets up outriggers Boom extends to length and latches to tree Top end articulates to obtain sample

Trailer/Boom Trailer attached to ATV Self-leveling outriggers Telescoping boom Attaches to tree with one arm Reaches further to collect the sample Similar overlapping sections that telescope Trailer/Boom

Feller Buncher Mark may climb the live section of the tree Device climbs up the dead section the tree Shears any dead limbs off Winches Mark up to the live section Telescoping boom moves up the live section

Feller Buncher Advantages Relatively Quick Hydraulic or Electrically Driven Simple Operation Disadvantages Complex design Expensive Cost Quite Dangerous Feller Buncher

Power Ascender/Grappling Hook Mark still climbs the live section of the tree Power ascender moves him up the dead section Rope is hung from the live section using a Grappling hook launcher Potato gun Sling shot Potato gun or sling shot has a fishing real attached to it

Power Ascender Atlas- climbs 10ft per second ActSafe- climbs 72ft per minute Gasoline can only go one direction Rental Cost $300 a day Purchasing Cost Unknown Power Ascender

Grappling Hook/Potato Gun Grappling Hook used to put a rope in a tree Sling shot puts the bean bag over the tree attached to fishing line and the rope is tied to the fishing line and pulled over the top. Potato cannon will do the same task as the sling shot of shooting the bean bag over a tree limb. Grappling Hook/Potato Gun

Mark Mark still climbs all of the tree Has a new lopper to allow him to cut samples quicker and easier

Mark Advantages Already can reach the sample Simplified Design Consistent Results Disadvantages Speed Inability to Fly Not Disposable High Repair Costs Mark
