Two servos are connected Rangefinders are being added Xbee communication is in the development stage Integration between Car/Crane/ASV on the way Fabrication of Car

Logic for all the systems is still in the development phase. – Logic paths are ready for programming. – Need to learn the syntax of arduino to complete coding. Logic of the Car/Crane

Initial Search Pattern Car rotates 360° Duel sensors recognize if object is in front of car Car drives straight to object

Failsafe Search Grid Car drives straight until edge Car follows edge On reaching a corner car follows a sweep pattern

Current Status on Retrieval Mechanism Due to no funding the work on this area has been postponed The work already done will be a good basis for future semesters to work with.

Crane Progress Most of the structural material has arrived. Still waiting for the motors and belts/gears.

Displacement Analysis A CAD analysis has been conducted. Each design has benefits and disadvantages. We need to have the least weight possible while keeping rigidity.
