Dear Sir or Madam,
I am an Electronics Specialist working on Arduino Systems for at least 3 years now. My current projects include several robotics projects. For example, I am working on a prototype for a medical technology company, which includes working with Arduino-based microcontrollers and the control of electric motors. Other projects are an intelligent robot (similar to yours) and an electric bicycle which uses a high-powered DC motor.
If you are interested in accepting me to work on your project, let's discuss on the details in the chat! It would also be lovely if you provided me with some more information like schematic drawings or pictures, so I can start with the work right away.
Best Regards,
Florian Saurwein
