I am assuming you don't want to buy a ready made robot, but instead you want to build a prototype robot from scratch for launching in market. I can help you with that. I have good knowledge with algorithms which you can see from my resume. And I will be hiring electrical and mechanical engineers along with me to build it. Please let me know if you would like to hire me.
I can design a 3d printed robot programmed with arduino capable of doing what you need or a more advanced robot using a Raspberry pi. I can develop a GUI to program it. I would like to talk more about your project if you like. Regards.
