Abstract
In the fields of robotics and mechatronics, the use of an experimental platform in the
learning process to allow for practical experience and demonstration of the core concepts cannot
be overemphasized. A real-life mini robotic arm is indispensable to the learning process in these
fields of study. There are commercially available robotic manipulators designed for educational
purposes. However, majority of commercially available robots applicable for undergraduate or
graduate levels learning are very expensive or have a closed hardware and software architecture. To
this end, an easy to fabricate and inexpensive three degrees of freedom electro-mechanical
manipulator is hereby presented. Sufficient information and design methodology employed in its
fabrication is succinctly detailed including working drawings, components materials specifications
and design calculations so that any student can reproduce the manipulator in the laboratory or
workshop. In terms of performance, the manipulator gripper successfully lifted differently shaped
payloads of 150g each of the test weights without slipping through the gripper jaws both when
stationary and when in motion. For the repeatability test, the calculated repeatability was ±0.088
mm this is within the range for common commercial robotic manipulators. The overall cost of
materials and standard components was NGN 38,000 (USD 77.00). The produced manipulator is
relatively cheaper compared to commercially available educational robotic manipulators.
