Scope of Robotics and Artificial Intelligence:

• It involves a lot may activities like maintenance and designing. Along with it the programming of the hardware and software is also an intrinsic role one who has done this course plays.
• It is always suggested that one does a postgraduation specialization after their Bachelor's, this will give them not just extended knowledge but also an edge over other aspirants. Going for further study options will also help you in getting better jobs and opening many other opportunities.
• Education is another field which is vastly affected by artificial intelligence. With changing times, classrooms are becoming smarter and in order to follow this trend mechanisms need to be developed. AI will enable the delivery of education in a personalised style suiting to the student's needs and interests. 
• They can work in the gaming industry where they can use their gained knowledge about artificial intelligence and robotics and put them into games in the X-Box and Playstation. Many innovations and evolution await in the gaming industry.
• You can get employed in companies like Google, Ola, Uber etc. which deal autonomous AI guided transportation. Algorithms and equations are deigned for effective functioning of these set ups. 
• International organisations like ISRO and NASA recruit individuals with wide knowledge about this field. These organisations make effective and innovative use of artificial intelligence and robotics.
• The vast knowledge in this field will also open jobs in the investigation departments. Police departments and intelligence agencies of the nation are in need of these technological advancements for their proceedings like bomb defusing, explosive situations, spying and investigation. 
• Robotics is a field which gives you a chance to serve in the medical department by providing it with certain devices and advancements which help doctors successfully perform surgeries for diseases which previously had no treatment. 
• Major job roles after this degree include those of robotic scientist, robotic engineer, robotic technician, software engineer, gaming developer, automation, computer scientist etc. 

All the best!
