Mission Statement

Design and prototype a robotic device to transport a low energy tablet to charging station for reenergizing.

Milestone

• Finish PDS Document• Decide final concepts• Finish BOM

Product Design SpecificationTraveling over hard surfaces and carpet.Ability to turn up to 180°Wirelessly travel up to 40 ftEasy to maintainEasy to interface the tablet to the robotCharge the tablet when docked

External ResearchRoomba Robot

Pros Auto navigating system Auto detect docking and recharging 40ft wirelessly travel and 180 degrees turn

Cons High cost ($350) Require extensive modification

External ResearchLine following technology

Pros Low price Easy to build

Cons Require specific route Not appropriate in room

with many objects

External ResearchEZ – Robot Kit

Pros Easy customize Friendly interface software Affordable ($218)

Cons Require additional board

to control motors

Internal ResearchChassis Designs

Design Pros Cons

Chassis – A Extremely stable Light weight

Limited turning Radius Extensive manufacturing Elaborate steering

mechanism

Chassis - B Stable Tight turning radius

Difficult to manufacture Too many parts Solid axle produces

turning issues

Chassis - C

Tight turning radius Light weight Simple

manufacturing

Possibility for instability

Internal ResearchTablet Holder

Design Pros Cons

Holder – A

Easy to manufacture No moving

components

Weight Lack of adjustability Height

Holder - B

Adjustable height Lowered center of

gravity during

transport

Difficult to manufacture Too many parts
