”AI2 Robot City” is a game-based learning kit for primary and secondary school students, which combines AI image-recognition teaching tool of MIT App Inventor and the computational thinking board game named as "Robot City." Through this learning kit, users will learn to make smart cars, create image-recognition models, write and perform mobile application. Users will learn to write a program to recognize the personal cards in the board game, and furthermore to control the smart cars with blue-tooth and compete in the computational thinking board game.

This invention targets at value-added increase for fish bone/scale by-products through a series of manufacturing units of steaming, pressure/ temperature,drying. The core design of pressure/temperature in terms of powdered machining equipment consists of a high pressure chamber, heating components, superheated steam,operations experiments as well.
