UNIVERSITY OF BALTIMORE DEPARTMENT OF HOMELAND SECURITY PROFESSIONAL DEVELOPMENT PROGRAM
TEACHERS: MR. MARVIN T. MARTIN AND MS. WILLIETTE HARBOR 5E LESSON PLAN TOPIC: ROBOTIC TECHNOLOGY AND HOMELAND SECURITY APPLICATIONS FOCUS: USING ROBOTS TO DIFFUSE HAZARDS OF DANGEROUS CHEMICALS, CHEMICAL SPILLS OR EXPLOSIVES.
FOCAL POINT: STUDENTS WILL APPLY CONCEPTS OF ENGINEERING PHYSICS TO DEVELOP SIMULATED CO NCEPTS OF ROBOTS TO RESPOND TO CHEMCICAL SPILLS OR CHEMICAL EXPLOSIVE.
Target Grade Level: 10th -12th grade
Lesson Objectives
Students will explore the concepts of Robotics subsystems and understand the engineering concepts of designing robotic prototypes. Students will design robots and build robots to meet specific obstacle tasks that would allow robots to response to chemical hazards and potential chemical explosives. Students will develop the engineering process for the development of the robots Students will develop robotics prototypes, test prototypes, develop the prototypes, prepare for design review, receive feedback, choose a solution, design model, and test the model
Students will develop a master schedule for engineering design and prototype model constructions Students will develop and master the design process for gear ratio for speed and mechanical advantages for robotics functions Students will be able to calculate the gear ratio for torque using the appropriate physics formulas Students will be able to calculate rpm for speed, acceleration and potential motion capacities for robotics to perform specific tasks
Materials Needed: VEX Robotics Kits Complete Parts
ENGAGEMENT: Capture of Student Interest. Students will review a series of short video clips on Robots used in military applications and law enforcements that includes removal of threats of chemical hazards. Observation of Student Built Robots performing obstacle tasks
Engagement questions
Explain why robots would be a resource to provide defensive and offensive tactics to prevent harm to people from potential chemical hazardous situation. List examples of the challenges that scientist and engineers would have in developing idealist robots that meet the engineering specifications to offset the harms of chemical hazardous. Elaborate on the cost factors on engineering robotic endeavors.
Exploration: Hands-on/minds-on activities. o Focus Points and Engineering Challenges. Students will construct the following system Students will be given the obstacle challenges.

CURRICULUM PLANNING YOUR PROJECT TEACHER CURRICULUM Planning Your Project / Note to Teacher 1 Vex 1.0 © 2006 Robotics Academy Inc. Note to the Teacher Planning Your Project: Technical Sketching The Planning Your Project section of the curriculum introduces students to technical sketching, a fundamental tool of engineers. The Background section is divided into the following sections: 1. Introduction to Technical Sketching 2. Drawing Conventions 3. Pattern Developments 4. Pictorial Sketching 5. Precision Measurement 6. How to Make Things Move 7. Vex Solid Models The Lesson section consists of a variety of hands-on technical sketching exercises for a variety of parts.
Description.
It will depend on the teacher s point of emphasis, but this section of the course Could take anywhere from one week to a couple of weeks. Introduce students to sketching early, challenge them with a design problem that involves building a working model. Have them plan their project before they build it. This process Involves sketches, dimensioning, and design reviews. Team members share ideas, and then make improvements based on testing and feedback. Students are required to sketch and dimension any non-Vex parts that they need to fabricate. Introduction to Technical Sketching consists of a PowerPoint presentation that the teacher can modify to introduce the topic, three short videos that demonstrate sketching technique, a set of handouts that explains sketching technique, and multiple sketching exercises.
Drawing Conventions consists of two printable PDFs illustrating technical sketching line conventions and general dimensioning rules. Pattern Developments
is a handout that introduces the topic of pattern development and provides several examples of student-designed manipulators that use pattern developments.
Pictorial Sketching consists of a PowerPoint presentation that reinforces
crating technique when sketching pictorial drawings, a pictorial sketching handout, and a pictorial sketching step-by-step video, which illustrates isometric drawing, oblique drawing, and the crating technique.
Precision Measurement consists of a PowerPoint that explains how to read a
dial caliper, micrometer, and engineering rule, a worksheet that involves accurately measuring a couple of Vex components, and a handout on units of measurement. How to Make Things Move consists of two PowerPoint presentations that explain how common moveable parts work and how to design moveable parts for various applications.
Vex Solid Models consists of a printable PDF Vex parts library, and both
Solid Works and Autodesk Inventor models of these parts. Note that your computer must have either or both of these programs to use these models. Designing & Building the Chassis System for the Robots ( Prototype) VEX robotics Parts and Equipment
Lesson Activity Science of Lever & Arm
Lesson Activity ( Gear Ratio) Power transmission is the movement of energy from its place of generation to a location where it is applied to performing useful work A gear is a component within a transmission device that transmits rotational force to another gear or device Gear Ratio Presentation
Lesson Activities should include testing, developing, programming and applying the use of sensors the small prototype robotics technology. Larger and more advance robotics can be built from prior FIRST robots no longer in use. However, the key to independence is the development of robotics brain or comptroller for an individual project.
