"Yoshihito is an amazing LEGO builder and it is truly a gift that he is sharing these ideas with the global LEGO community!"
Milluzzi Labs

"Each model is built with pieces in a wide range of colours, making it easier to see what parts are used and how they are connected. Pictures from different angles of each build provide enough information to reverse engineer all of the contraptions for even the most inexperienced builder."

Yoshihito Isogawa's books are a wonderful learning guide for young mindstorm and/or lego technic enthusiasts. I have used his series for years to train my First Lego League teams on simple machines.
