As per your ask , here is my understanding from the background level.
You need to make RPA s/w solution on your final project.
There can be two solutions :
1. If you project comprises on RPA s/w , then you need to create a new tool from scratch.
2. If the project demands RPA solutions, then pick up any of the RPA tool which is available free of cost from the market and train your BOT.
But I believe since there are so many tools available in the market your project criteria should meet training the bot , i.e RPA tool , mimicing any human activity followed by creating the tool from the scratch.
You can even implement AI ,if you want to show it dynamic and vast.
