Cobol to Java Converter - A translator project that converts cobol code to java

Hi

We are trying to make an initiative to make a Java Project that convert Cobol code into Java.

The project on going one

so the latest code will be updated in the repository

https://github.com/konzerntech/CobolToJava



Thanks

Artificial Intelligence Robot prototype in Java

Developed a prototype of Artifical Intelligence robot, that can walk a maximum of 5 kilometer on battery charge
For each 1 kg of weight additional charge is used.
