| Step | Action | Reason | |------|--------|--------| | 1 | Verify source – download only from the official VEX community site, a trusted GitHub repo, or a direct link shared by the project owner. | Prevents malware and respects intellectual‑property rights. | | 2 | Check the file hash – the provider may list an MD5/SHA‑256 checksum. Run certUtil -hashfile venx267upart04.rar SHA256 (Windows) or shasum -a 256 venx267upart04.rar (macOS/Linux) and compare. | Guarantees the file wasn’t tampered with. | | 3 | Scan for viruses – run the file through Windows Defender, ClamAV, or an online scanner such as VirusTotal. | Extra safety net against hidden threats. | | 4 | Extract – use a modern RAR extractor (WinRAR 6+, 7‑Zip, PeaZip, or the built‑in macOS “Archive Utility”).

    • | Symptom | Likely Cause | Fix | |---------|--------------|-----| | Robot never lifts | Motor ports mismatched in code vs. wiring diagram | Double‑check motor_port assignments in main.cpp against the wiring diagram PDF. | | Jittery arm movement | PID D term too high or sensor noise | Reduce D or add a low‑pass filter (filter = 0.1 * new + 0.9 * old). | | CAD parts don’t fit | Different VEX part revisions (e.g., 2022 vs. 2024 chassis) | Verify part numbers in parts_list.csv; download the correct CAD library from VEX’s site. | | Compilation errors | Missing PROS SDK path or outdated compiler | Re‑run the PROS installer; ensure PATH includes $PROS_HOME/bin. | | Simulation diverges from hardware | Friction coefficients or motor specs differ | Adjust simulation_params.yaml (e.g., motor_max_rpm, gear_ratio). | venx267upart04rar link
