The degree of freedom of S was five, so that the hand posture of S at an arbitrary position was restricted. The degree of freedom V is improved to be six, so the hand of V can move to an arbitrary position with any posture. The structure of the joints nxt 4 axis robotic arm design V is the same as a general industrial 6-axis vertical articulated robot. I aimed to make the shape of the robot slim.

The robot V is easy to build in a smaller size because new Lego parts such as medium-sized servo motors and tooth turntables nxt 4 axis robotic arm design available. The spring balancer is used only at the second joint that is subjected to the heavy duty. I had difficulty in making the turning bearing of V It is subjected to large bending moment when the arm takes a horizontal posture.

It is difficult to bear the moment only by a single turntable part. In order to solve the problem, I added a bearing that is consist of 4X4 size macaroni parts and roller parts in addition to a regular bearing made from a turntable part. A pair of bearings disperse the stress caused by bending moment. The structure achieves both of the strength against large moment and the slim shape of the hip of the robot.

I temporary used two light sensors to enable two EV3 bricks to communicate with each other by synchronizing signal. The EV3 bricks calculate the inverse kinematics of the robot in real time and solve the angle of the each joint from the target position and posture of the hand. In the demo video, the movement from a start position to a target position is calculated in different two modes. In the linear interpolation mode, the movement of the hand draws a linear locus.

In the joint interpolation mode, the movement of nxt 4 axis robotic arm design hand does not draw a linear locus. I am planning to attach a chuck at the tip of the robot and the robot can be used for material handling. Your email address will not be published. Please input characters displayed above.

Educational robotics is a broad term that refers to a collection of activities, instructional programs, physical platforms, educational resources and pedagogical philosophy. There are many schools which are using the robot teacher.

The primary of objective of educational robotics is to provide a set of experience to facilitate the student's development of knowledge, skills and attitudes for the design, analysis, application and operation of robots. The term robot here is used quite broadly and may include articulated robots, mobile robots or autonomous vehicles of any scale. The rigor of the approach can be scaled based on the background of the target audience and may be suitable for students across the entire educational spectrum—from elementary school or graduate programs.

An alternate, or secondary, objective is to use robotics as a tangible and exciting application to motivate and facilitate the instruction other, often foundational, topics such as computer programming, artificial intelligence or engineering design. Robotics engineers design robots, maintain them, develop new applications for them, and conduct research to expand the potential of robotics.

First-year computer science courses at several universities now include programming of a robot in addition to traditional software engineering-based coursework. Since , companies like Cytron Technologies has been making inroads into schools and learning centers with their rero reconfigurable robot. Designed to be easy and safe to assemble and easy to program, robotics became very accessible to young children with no programming skills and even up to advance users at tertiary level.

Robotics education was heavily promoted via roadshows, science fairs, exhibitions, workshops, camps and co-sponsored classes, bringing robotics education to the masses. From approximately though , robotics education at post-secondary institutions took place through elective courses, thesis experiences and design projects offered as part of degree programs in traditional academic disciplines, such as mechanical engineering, electrical engineering, industrial engineering or computer science.

Since , more universities have begun granting degrees in robotics as a discipline in its own right, often under the name "Robotic Engineering". Based on a web-based survey of robotics educators [4] , the degree programs and their estimates annual graduates are listed alphabetically below.

Note that only official degree programs where the word "robotics" appears on the transcript or diploma are listed here; whereas degree programs in traditional disciplines with course concentrations or thesis topics related to robotics are deliberately omitted.

The Robotics Certification Standards Alliance RCSA is an international robotics certification authority that confers various industry- and educational-related robotics certifications. Several summer camp programs include robotics as part of their core curriculum.

Many schools across the country are beginning to add robotics programs to their after school curriculum. From Wikipedia, the free encyclopedia. Teaching Novices Programming using Robots" pdf.
