Project Proposal: 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: 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. send you previous work before messaging.
