      Cám ơn chị Clytie đã thông báo.
Nếu có trục trặc xảy ra thì có thể chuyển đoạn mã sang Pyhthon cho robot chạy, tuy nhiên mong rằng không có chuyện này xảy ra, vì tiêu bản vẫn chưa sửa hết lỗi. Từ ngày mai (12/08) đên hết tháng 8 em đi chơi, nên sẽ có ít thời gian vào mạng; hy vọng khi về thì sẽ thấy mọi chuyệnôổn thỏa.
Trung.
