Hello

I am looking for fully autonomous robotic platform with navigation software carrying out loads up to 10 kg. The main requirement is that the navigation platform has to be low cost. The budget is up to 2000 Euro. The robot has to execute the control trajectory according to desired coordinates set by the operator. Could somebody send any link of companies offering such navigation platforms of give me an advise how to proceed? I see a lot of robotic platforms using ROS technology for control. May I use ROS for creation of GUI for control or I can send instructions for control via the terminal?

Thank you
