Robot Arm Java

Dears,

i am a student of media art school and looking for a robot arm for my projekt.
The robot arm schould cover an area of 40 * 40 * 30 cm and move quite fast and strong.
i need direct access to the 3d movement functions (like forward kinematics) of the arm
a java api would be great.
My maximum budget for this is 1500 euros.

i would really appreciate your recommendation.

Sincerely,
Ji Hyun Park
