Goal: To mutually define the project Self-organized (Agenda and Discussion) A place for the discussion of the most important issues for you Facilitation (Help needed)

Streamline Development

3 iterations 2 weeks each kick-off - next Monday

Research report● generate report in the research phase● help to estimate time

Group Division

● 10 Groups, 6-8 members each● Groups are not component focused● Groups initially have a work package● How to apply?

Groups and the Initial tasksGroup Number Initial task

Alpha (Αα) Build Hovercraft Body

Beta (Ββ) Build Skirt

Gamma (Γγ) Propulsion Module

Delta (Δδ) Control Fan Speed

Epsilon (Εε) Rudder Control Send Command

Zeta (Ζζ) Send/Receive Data on PC

Eta (Ηη) Send/Receive Data on Hovercraft

Theta (Θθ) Basic Instruction Scheduling

Iota (Ιι) Determine Speed

Kappa (Κκ) Measure Pressure

Build Hovercraft Body (Alpha)

● Hovercraft blueprint● List of building materials for approval● Manufacturing the hovercraft body

Build Skirt (Beta)

Build the skirt of the HC prototype Main requirements● Durable and replaceable parts● Fit on HC body

Propulsion Module (Gamma)

● Blueprint of the propulsion module● Material list for approval● Construction and attachment of the module

Control Fan Speed (Delta)

● Hovering fan for controlling hovering ● Propulsion fan for controlling the speed

Rudder Control (Epsilon)

Control the rudder to control steeringTasks● A clearly defined API for all other groups to

use including: center, left and right movements

Send and Receive Data on PC (Zeta)

● message sending and receiving on PC● Select communication interface (WiFi,

Bluetooth, XBee, etc.).

Send and Receive Data on Hovercraft (Eta)

● message sending and receiving on the hovercraft side

● The Arduino should check for incoming messages, have a mechanism to save or use them, and send replies

● Define a protocol, which can accommodate the different data types the hovercraft uses

Basic Instruction Scheduling (Theta)

● implement simple control loop to manage tasks

● every thing that needs to be accomplished should be guaranteed to execute

Determine Speed (Iota)

Measure real-time speed Main Requirements:Measure the speed at an appropriate intervalUse a filter to clean the data (Ex. Kalmer Filter)

Measure the air pressure Main Requirements:Select a pressure sensor that measures the correct pressure rangesThe sensor should be selected from www.elfa.seCompatible with Arduino

Measure Pressure (Kappa)
