Hello,
I've been working with Robotics for 3 years and I've done Humanoid style robots, Auto navigation robots, Line following robots, Robotic Arms, and various other automation related projects I can't go into details about. With this amount of experience I already have a list of parts ready for you that can be used to build a robot for this functionality and if you would be kind to award me the work we could get start talking about it right away.
Thanks.
