I send them a linecheck field to help me solve it and it is around 200 USD. The solution is fast as the field is 10 square meters long but the robot they created can solve it in 42 seconds! It requires three days for them to send the program and ldd file to me. But there is a problem to me is that this doesnt work on similar fields. The program only works for the specific field that i sent to them. Fortunately, it is easy to tune as they used english myblocks which is easy to understand. If you want to get an efficent, faster way of solving your field, do not hestitate to give it a shot!
