Scope

Note

Dear reader. This page can be seen as a journey that shows my progress related to my final project; more or less seperate from my weekly assignments. This page started out as a kind of schedule but basically it has alsways been about scope. I tried to us it as a schedule but was never happy about that. So I changed that in week 16.

Last update: week 16

From a functional milestone perspective (spiral design) I want to accomplish:

  • a platform that floats (with batteries, motor); no water coming in; motors run
  • duck is attached on top with magnets; it's balanced
  • duck is able to move autonamously to centre of geofenced area
  • duck is able to follow a preprogrammed route of waypoints (within the geofence)
  • duck is able to detect a human head in the water; move towards it and store the image

From a finished perspective "make it nice" I want to accomplish:

  • hull is smooth, waterproof
  • the duck can be opened and closed to reload the power bank
  • electronic boards/ pcb are in a casing to protect against water
  • power lines are marked 5V / 12V with nail polish
  • make a stand to keep the hull and duck in place
  • optional: pogo pin can be used on the outside to turn on/off the 12V circuit (to the motors)
  • optional: hull sprayed with lak
  • optional: 12V wires to both motors are shielded/ grounded to prevent noise from the PWM

Remark: below are older ideas about my scope

Updated week 11

From a milestone perspective (spiral design) I want to accomplish:

  • a platform that floats (with batteries, motor) can be moved using RC
  • extension: duck can be attached on top, no water comes inside the duck
  • extension: duck is able to move autonamously according to a pre programmed route
  • extension: duck is able to take/store picture when it has reached a way point
  • extension: duck is able to take/store picture when it detects a boey
  • extension: duck is able to randomly move within geofenced area
  • extension: duck is able to move towards a boey autonomously and take/store a picture at 8 meters
  • extension: duck is able to detect a duck, move slowly towards it and take/store a picture at 5 meters
  • extension: duck is able to detect a human head in the water; move towards it and take/store picture at 2 meters

Updated week 12/13

Basics

  • [10] a platform that lets the duck float and is water tight; duck is attached with tie wraps to the platform
  • [11] add waterjet thruster and steering of the thruster; still water tight
  • [12] add battery inside the platform; doesn't sink; doesn't flip over
  • [13] add DC motor inside the platform and attach it to the impellor; doesn't sink; doesn't flip over; is in balance
  • [14] connect the motor to the battery and 'feel' the thrust in the water; holding it with both hands
  • [15] add servo inside the platform attached to the steering; doesn't flip over; is still in balance
  • [16] loosely add RC receiver, servo and DC motor controller and try out the movements

Location awareness

  • extension: duck is able to move autonamously according to a pre programmed route
  • extension: duck is able to take/store picture when it has reached a way point
  • extension: duck is able to randomly move within geofenced area

Intelligence

  • extension: duck is able to take/store picture when it detects a boey
  • extension: duck is able to move towards a boey autonomously and take/store a picture at 8 meters
  • extension: duck is able to detect a duck, move slowly towards it and take/store a picture at 5 meters
  • extension: duck is able to detect a human head in the water; move towards it and take/store picture at 2 meters

Schedule

April 22 - 28: I'll use my individual assignment to create the platform that can also hold the waterjet outlet and steering of the thruster

April 29 - 5th May:

  • I'll use my individual assignment to write an application that interfaces a user with an input &/or output device that you made
  • I'll create a 3D design to be used inside the platform that holds

May 6 - 12: use it to Design and document the system integration for your final project

May 13 - 19: wildcard week

May 20 - 26: plan final masterpiece

May 27 - 3th June: finish the final project

Updated week 15

Adjusted based on first trial with a 3D printed hull.

From a milestone perspective (spiral design) I want to accomplish:

  • a platform that floats (with batteries, motor) can be moved using RC
  • extension: duck can be attached on top, no water comes inside the duck

  • extension: duck is able to take/store picture when it has reached a way point

  • extension: duck is able to randomly move within geofenced area
  • extension: duck is able to detect a boey, move towards it and take/store a picture at 8 meters

Build/design steps

  • [15a] copy cat the way steering works with RC boats without water coming in
  • [15b] add servo inside the platform attached to the steering; doesn't flip over; is still in balance
  • [16] loosely add RC ~~receiver~~ to control servo and DC motor and try out the movements

Location awareness

  • [17] extension: duck is able to move autonamously according to a pre programmed route
