Design Method and Example of a Simple Educational Robot

Abstract

Nowadays educational robots have begun to walk into campuses and households, changing the traditional way of teaching and learning. There are many physical or virtual robot education platforms on the market now, whose perfect systems and mature hardware or software not only reduced the difficulty of learning but also limited the creativity of users. Taking this as a starting point, this paper proposed a method of designing a simple robotic arm system, including motion analysis and control algorithm design, and verified it through an example. Generally, the method proposed in this paper can help robot enthusiasts, especially beginners, to explore and practice the process of building robots just with simple materials.

Design and Fabrication of a Manually Controlled Electro-Mechanical Manipulator for Educational Purpose

“…Tan α = = 0.0637 (8) Ø1= virtual friction angle, tan Ø1= µ1 µ1= (9) where µ (coefficient of friction between screw and nut) is taken as 0.15 [13] β= semi angle of the ACME thread.…”

“…Like the human arm, a robotic arm mechanism or manipulator consists of arms (links) and joints (steering gears). The modelling and kinematics analysis of the manipulator structure studies the mapping relationship between the end position of the arm and the output of every joint [9].…”
