Free, useful videos related to robotics as there is no method of earning the robocoins as high as 5,000. So, unfortunately, I cannot learn anything with Robociti! I thought it would help me but it didn't and I am sad about it and now, I am going to look for some other website for learning. Please do as I have suggested. Please keep some 5-6 courses related to AI and robotics free, so that I can get my basics right and participate in competitions and earn many robocoins for other courses. Please bring this to reality. I hope this suggestion will lead to some development of the website www.robociti.com
