This is a well-constructed kit with large enough servos to make a robust small to medium sized robotic arm with five degrees of freedom. It includes brackets, fasteners and various servos that can be assembled. The kit also has some software provided to control the robotic arm manually. The instructions for building are online only. If assembled and disassembled, some parts may wear and need to be replaced.--Ministry of Education website.
