This program, robot_kinematics, requires the Eigen library in order to compile. Note that the downloaded library might have a different folder name from what was written in the code (Eigen), therefore make sure the two names are the same, otherwise the compiler will throw you an error.
A sample command for compiling the source code is g++ -std=c++11 ./src/arm.cpp ./src/kinematics_calculator.cpp -I /usr/include/ -I ./include/ -o robot_kinematics assuming the Eigen library is installed under /usr/include.
This program is to be used in conjunction with philos_project to reflect the robot design.
