This tutorial provides background information on robotic arm technology and practical instructions for building your own. The author includes free-body diagrams, schematic drawings, help with performing force calculations in the joints, directions for setting torque parameters, and detailed explanations of each component in the system. For learners with little background in physics or engineering, the Robot Arm Calculator Tool determines the lifting capability of the robot arm.
This resource is appropriate for courses in introductory physics or applied physics.
Please note that this resource requires
Editor's Note:See Related Materials to quickly build a multimedia module for high school on the physics of a robot arm.

1. The Nature of Science
1C. The Scientific Enterprise
6-8: 1C/M3. No matter who does science and mathematics or invents things, or when or where they do it, the knowledge and technology that result can eventually become available to everyone in the world.
2. The Nature of Mathematics
2B. Mathematics, Science, and Technology
9-12: 2B/H3. Mathematics provides a precise language to describe objects and events and the relationships among them. In addition, mathematics provides tools for solving problems, analyzing data, and making logical arguments.
3. The Nature of Technology
3B. Design and Systems
9-12: 3B/H3. Complex systems have layers of controls. Some controls operate particular parts of the system and some control other controls. Even fully automatic systems require human control at some point.
9-12: 3B/H5. The more parts and connections a system has, the more ways it can go wrong. Complex systems usually have components to detect, back up, bypass, or compensate for minor failures.
11. Common Themes
6-8: 11A/M2. Thinking about things as systems means looking for how every part relates to others. The output from one part of a system (which can include material, energy, or information) can become the input to other parts. Such feedback can serve to control what goes on in the system as a whole.
6-8: 11A/M3. Any system is usually connected to other systems, both internally and externally. Thus a system may be thought of as containing subsystems and as being a sub-system of a larger system.
9-12: 11A/H2. Understanding how things work and designing solutions to problems of almost any kind can be facilitated by systems analysis. In defining a system, it is important to specify its boundaries and subsystems, indicate its relation to other systems, and identify what its input and output are expected to be.
9-12: 11A/H4. Even in some very simple systems, it may not always be possible to predict accurately the result of changing some part or connection.
