Robotpark 6 DOF Aluminium Robot Arm Kit is a robotic arm system that has six degrees of freedom and a gripper to manipulate objects in the environment. The servo motors that control the arm links are included in the pack. To start using the robotic arm, the only thing you have to do is to use a microcontroller system like Arduino and write a program that controls the servo motors.
The mechanic links of the robotic arm is built using hard aluminium brackets in different shapes. It is pretty easy to connect servo motors and brackets together to build the robotic arm.
Note this is a kit - assembly required.
