Gun Turtle

A robot in the Prison Series.

A self-propelled robot soldier that has been officially adopted by the land forces of the Space Federation Army.

When in battle, it transforms into a 150-centimeter-long ball, and attacks with its high-performance blaster while flying at heights of one to two meters.

To control a self-propelled robot soldier, you need a portable control console (like a small laptop computer), from which you send a simple program, and it moves according to the program's commands.

The program can be changed at any time, but only simple and basic movements and rules can be programmed, so the difference between a good Gun Turtle and a bad one is how to change the program according to the enemy's movements and the situation, and how to build a basic behavioral program to deal with complicated situations.

Appearance
150-centimeter-long white ball that can open up.
