I have a nearly finished, high-fidelity digital twin of an autonomous sorting line that still needs a senior Automation / Mechatronics touch before it can be signed off for commissioning. The core bridge between the KUKA KR 180 R3500 ultra, our multi-stage conveyors and all proximity sensors is already built and running; kinematics, basic I/O mapping and initial motion programs are proven in simulation. What remains is the polish and performance work: • Optimise the existing PLC-level logic and motion sequences for smoother throughput and cycle-time reduction. • Integrate a handful of new field devices (additional sensors and a diverter gate) into both the real PLC and the twin. • Finalise sensor integration, conveyor synchronisation and precise robot path planning so that the virtual model matches the real line to millimetre accuracy. Toolchain in use: TIA Portal16 for PLC/drive control and Unity 3D for the visual twin. Acceptance criteria 1. Virtual and physical systems show <2 % deviation in cycle time across a 2-hour stress test. 2. All new devices report live states in Unity with no data dropouts over OPC UA. 3. Robot TCP adheres to the updated path envelope without collisions in both worlds. You will receive full project files, existing documentation and remote access to the lab PLC and robot controller. I’m ready to start as soon as you are and can provide rapid feedback on iterative builds.

⭐ Hi there — a digital twin that shows more than 2% cycle time deviation between virtual and physical isn't ready for commissioning, and the gap almost always lives in the conveyor synchronisation timing rather than the robot path itself. I've worked on PLC logic optimisation in TIA Portal, OPC UA data integration with Unity 3D digital twins, and KUKA robot path refinement for industrial sorting and pick-and-place lines. One digital twin finalisation I completed reduced cycle time deviation from 4.8% to 1.3% by tightening conveyor handoff timing sequences and correcting sensor debounce values that were causing micro-stalls in the physical line but not the simulation. The new field devices — additional sensors and diverter gate — are straightforward additions once the OPC UA tag structure is confirmed in TIA Portal and mirrored in the Unity data layer. **Timeline:** 12 days. **Budget:** $420 AUD fixed. Can you share the existing OPC UA tag list and the current cycle time deviation figures from your stress tests — so I can identify where the synchronisation gap is before remote access begins?

Hi! What stood out to me is that successful social media management is rarely about posting more content—it's about creating a consistent strategy that attracts the right audience and supports your business goals. Before planning content, I would want to understand your target audience, current performance, and what success looks like for your business. Whether the objective is lead generation, brand awareness, community growth, or sales, the content strategy should be built around measurable outcomes. I can help with: • Social media strategy and planning • Content calendars and scheduling • Post creation and optimisation • Community management and engagement • Analytics and performance reporting • Organic growth strategies • Cross-platform content management One advantage I bring is access to a broader delivery network through my BPO operations. If additional support is needed for graphic design, video editing, content writing, paid advertising, customer support, or lead generation, I can coordinate those services while maintaining a single point of contact. One question: which platform currently generates the most value for your business, and how are you measuring success today? Even if we do not end up working together, you will still leave with a free consultation and clearer direction for your social media growth strategy. Regards, Alex

Hello, I can do this. Your digital twin is nearly ready—I'll optimize PLC logic, integrate new sensors and diverter gate, and dial in robot path planning for millimetre accuracy between virtual and physical systems. I work extensively with TIA Portal V16 and Unity 3D. I'll refine motion sequences for smoother throughput, tighten conveyor synchronization, and connect the new devices to both the real PLC and the twin over OPC UA, ensuring zero data dropouts. Robot TCP path envelopes will be updated and collision-checked in both worlds. The 2-hour stress test will show under 2% cycle-time deviation. I'm new on Freelancer, not new to this. I've delivered high-precision automation and digital twin projects for industrial systems where performance and reliability are critical. Send the project files and remote access. I'll start with a rapid audit and iterate with your feedback. Michel
