Compact Drone 3D Conceptual Design (Only for Korean Company)

Project Proposal Only for Korean Company: Integrated 3D Design and Magnetic Docking Station for a Compact Drone
This proposal defines the scope, deliverables, timeline, and key assumptions for delivering a fully integrated 3D model of your compact drone and a matching bowl-shaped magnetic docking station with charging and guided-movement features.

1. Objectives
Design and deliver:

A detailed 3D CAD assembly of the drone, including all internal components fixed within its shell

A complementary bowl-shaped docking/charging station that magnetically latches, aligns, charges, and permits limited yaw/roll movement

Daily video recordings of the modeling process for documentation

2. Drone Design Specifications
Derived from your image, targets are:

Maximum diameter/height: 23 cm (smaller preferred)

Total mass: ~450 g

Propulsion: single shielded propeller beneath a protective skirt, with four adjustable vanes for attitude control

Payloads & subsystems:

Single Board computer and Flight controller

Wi-Fi module

Dual-core onboard computer

HD downward camera

Sonar sensor

Bottom-facing navigation camera

3. Docking Station Features
3.1 Guide & Alignment
Tapered bowl shape with smooth, inward-sloping walls or spiral guide to funnel the drone into ±2 cm lateral tolerance

Hall-effect sensors at three equidistant points confirm correct seating before charging

3.2 Magnetic Latching
Flush-mounted electromagnets in segmented “petals” around the bowl perimeter

Ferrous plates on the drone’s skirt engage the magnets to pull it flush

3.3 Power Transfer
Three spring-loaded pogo pins on the station contact matching pads on the drone belly (12 V/10 A capacity)

Overcurrent protection via on-pad fuse and current-sense resistor

3.4 On-Pad Mobility
Low-friction nylon rollers inside the bowl allow the drone to yaw or roll once magnets disengage

Controlled-release detent springs hold the drone steady during charging but yield under ~2 N lateral thrust

3.5 Control Logic Sequence
Drone descends into the bowl guide

Hall sensors verify seating

Electromagnets energize and charging begins

Upon full charge or command, magnets de-energize

Drone uses thrust to pivot off rollers and depart

4. Scope of Work
3D Modeling

Drone external shell, internal mounts, and each component housing

Docking station bowl, magnet pockets, pogo-pin block, roller mounts, and sensor cutouts

Component Placement

Placeholder geometries for Wi-Fi module, computer board, camera, sonar, propeller, battery, etc.

Process Documentation

Daily screen-recorded videos capturing key modeling milestones and decisions

5. Deliverables
3D CAD Assemblies

STEP (.stp)

STL (.stl)

Native CAD files (e.g., SolidWorks or Fusion 360)

Technical Drawings & BOM

Basic exploded views and parts list

Process Videos

Daily exported video files (screen captures, narrated as needed)

6. Timeline & Budget
Duration: 2 weeks from project start

Budget: $200 for the conceptual design and station concept above with daily video documentation

Notes: Any additional engineering analysis, detailed simulation, or manufacturing-ready drawings would require a separate agreement.

7. Information Needed Before Kick-Off
Please provide:

Exact dimensions or CAD models for the Wi-Fi module, dual-core computer, HD camera, sonar unit, motor/propeller, and battery (size, weight, mounting interfaces)

Preferred chassis material (e.g., ABS, PLA, carbon fiber)

Once these details are confirmed, work will begin immediately.
