The Ministry of Education has recently organized an invention exhibition that showcases university students' creative designs, including the remote-controlled pet gate and the feeding machine that automatically dispenses food for pets when the owners are away.

Another brilliant invention is a system that can remove the scales of fish, which has become a great helper in the fish factory.

Using this remote sensor system, pet owners can open doors and feed their pets even when they are not at home.

The system was developed by a St. John's University student, and features an electronic feeding dish that opens at pre-set times when pets approach it.

The system can be controlled remotely online, and allows pet owners to monitor their pets when they are away.

Another student invention that received a great deal of attention was an electronic fish descaler that was designed for installation at fish markets.

The mechanism can descale 50 kilograms of fish at once, and is able to remove 100% of fish scales without affecting the meat. The unit can replace ten workers, and is already in mass production.
