Drone Safety Cage Electrical Design

# Freelance Electrical Engineer Needed – Electrical Design and Control Cabinet for Drone Safety Cage ## Project Overview I have already completed the mechanical design of a protective cage (approximately 2.5 × 2.5 m) in Autodesk Inventor. I only need the complete electrical part of the project. I am looking for a freelancer who can design the electrical system, select and integrate all electrical components, and create the control cabinet design. **The mechanical cage does not need to be redesigned. Only the electrical components and their integration into the existing Inventor project are required.** ## 1. Existing Project - Protective cage already designed in Autodesk Inventor. - One access door. - Drone operated inside the cage. - Drone power supply: 24 V DC / 10 A. - Separate 24 V DC power supply for the safety control system. ## 2. Required Electrical Components The electrical design must include: - Safety controller (Pilz PNOZmulti 2 or suitable alternative). - Safety door switch with electrical guard locking. - Multiple safety contact mats (Sicherheitskontaktmatten) inside the cage. - Manual reset button (Reset-Taster) outside the cage. - Two redundant safety contactors for the drone power supply. - Contactor feedback monitoring. - Main switch. - Power supplies (24 V DC). - Fuses and circuit protection. - Relays, if required. - Terminal blocks and wiring accessories. ## 3. Required Work ### A. Electrical Circuit Design - Complete electrical schematic (Stromlaufplan). - Safety circuit for the door and contact mats. - Reset and control circuit. - Contactor circuit with feedback monitoring. - Component selection and compatibility checks. ### B. Control Cabinet Design (Schaltschrank) - Select and arrange all electrical components. - Position safety controller, relays, contactors, power supplies, fuses and terminals. - Create a complete control cabinet layout. - Show component mounting positions and wiring connections. ### C. Autodesk Inventor Integration - Use my existing Inventor project. - Add only the required electrical components. - Integrate the control cabinet and its internal components into the existing CAD assembly. - Provide a 3D representation of the electrical installation. - Do not redesign or modify the mechanical cage. ### D. Technical Documentation - Electrical circuit diagrams. - Control cabinet layout. - Terminal connection diagrams. - Cable and wiring list. - Bill of materials (BOM) with manufacturer names and part numbers. - Editable CAD files and PDF documentation. ## 4. Required Experience - Electrical engineering. - Industrial automation. - EPLAN Electric P8 or AutoCAD Electrical. - Autodesk Inventor. - Control cabinet design. - Safety controllers and safety relays. - Safety contact mats and door interlocks. - EN ISO 13849-1 knowledge. ## 5. Deliverables The freelancer must deliver: 1. Complete electrical design. 2. Electrical component integration into the existing Inventor project. 3. Complete control cabinet design. 4. Electrical schematics. 5. Terminal and wiring diagrams. 6. Bill of materials. 7. Editable source files and PDF documentation. ## 6. Budget and Proposal I am looking for a cost-effective freelancer, preferably based in India. Please provide: - Fixed-price quotation. - Estimated completion time. - Examples of previous electrical cabinet designs. - Examples of similar safety-system projects. - Confirmation that you can work with Autodesk Inventor. I am looking for someone who can complete the electrical engineering and CAD integration, not just draw a basic electrical diagram. The design must be suitable for review by a qualified machine-safety engineer before construction and operation.
