في عصر التكنولوجيا الحديثة، ظهرت الروبوتات وكان صنعها قليل ومحدود ، ومن ثم بدأ الموضوع في الانتشار ، وأصبحت الدول الأوروبية هم الأكثر استخداما للروبوتات، بالطبع ان التكنولوجيا تمدنا بالأشياء النافعة لكن لكل شيء يوجد مخاطر وتحديات ، في هذا التحقيق سنعرض هذه الظاهرة ونتناول تأثيرها علي مستقبلنا ، لنفهم كيف يمكننا التصدي لهذه التحديات .
كشفت صحيفة ديلي ميل البريطانية عام 2023 ان احد روبوتات شركة تسلا قام بمهاجمة مهندس داخل المصنع بولاية تكساس الامريكية حيث استطاع الروبوت تثبيت الرجل ثم غرس مخالبه المعدنية في ظهره وذراعه تاركا سيلا من الدماء علي أرضية المصنع .
والسؤال الان الي أي مدي يمكن ان يتكرر هذا العطل ؟
وضح” د/ احمد سعيد “، معيد في كلية حاسبات ومعلومات ، ان هناك العديد من حالات تعدي الروبوتات علي البشر ، وقال ان هناك تقارير عن استخدام الروبوتات العسكرية في النزاعات ، مما ادي الي وقوع إصابات بشرية ، وأضاف ان الأسباب المحتملة تشتمل أخطاء في البرمجة ، وعدم وجود معايير صارمة في تصميم الروبوتات، كما أشار الي ان الروبوتات قد تتصرف بشكل غير متوقع اذا تعرضت لأحداث غير متوقعة او ظروف غير عادية .
كما تحدثت “المهندسة سارة يوسف” ، مبرمجة في شركة تكنولوجيا ، ان الأخطاء البرمجية مثل عدم معالجة الاستثناءات بشكل صحيح او وجود ثغرات في تعليمات التحكم يمكن ان تؤدي الي تصرفات عدوانية ، هذه الأخطاء تجعل الروبوتات تتجاهل أوامر السلامة .
وأشار المهندس ” كريم حسن ” ، خريج كلية حاسبات ومعلومات ويعمل في مجال البرمجة ، الي ان هناك عدة تدابير امنية يمكن اتخاذها ، مثل تطوير بروتوكولات امان صارمة ، واستخدام أجهزة استشعار لتقليل التفاعل غير المرغوب فيه مع البشر ، وتطبيق تقنيات التعلم الالي لتحسين سلوك الروبوتات .
كما اخبرتنا المحامية “نجلاء عبد الرحمن ” ، ان القوانين الحالية لا تغطي بشكل كافي اعتداءات الروبوتات ، وأكدت ان هناك حاجة ملحة لتطوير تشريعات جديدة تركز علي حقوق الافراد و تحدد مسؤليات الشركات المصنعة .
ومع استمرار تقدم التكنولوجيا، يبقى التحدي الأكبر هو ضمان أن تكون هذه الآلات أدوات لخدمة البشرية، وليس تهديدًا لها. من خلال العمل الجاد والالتزام بالمعايير العالية، يمكننا بناء مستقبل آمن ومشرق حيث تتعايش الروبوتات والبشر بسلام.
