Biologically Inspired Robotics Drexel RET Summer 08 Ari Ford Define Learners This Unit is designed for 8th grade students at Woodbury Junior-Senior High School. The students from Woodbury are a heterogeneous group of suburban students. Lesson groupings during the unit vary on a continuum between individuals, group and whole class. Standards – New Jersey State Technology Standards 8.1.12.9 - Create and manipulate information, independently and/or collaboratively, to solve problems and design and develop products. 8.2.12.3 - Develop methods for creating possible solutions, modeling and testing solutions, and modifying proposed design in the solution of a technological problem using hands-on activities. 8.2.12.6 - Create a technological product, system, or environment using given design specifications and constraints by applying design and engineering principles. Topic Students will use LEGO Mindstorms, NXT robots or K’Nex to design, build and program a robot that models the movements of a biological system (i.e. a fin, arm, leg, neck joint, ect.) Curriculum Links The units students studied prior to this unit are basic robot construction and programming. The main concepts students acquired from the programming unit were how to build simple robots and incorporate time, motor speed and sensors into basic programs. For example students would program their robots to navigate a cave on mars using an ultrasonic sensor or clear a Moon base of rocks using time and speed as dependent variables. The unit that will follow this is a Sumo-Bot unit. Students will compete to design, construct and program a robot to push an opponent out of the ring. Students will be given size, weight and part constraints. Objectives The students will be able to describe biological systems and biologically inspired robotics The students will be able to design, construct and program a biologically inspired robot The students will be able to summarize and analyze the design, construction and programming process. Materials LEGO Minstorms NXT LEGO Robots K’Nex RoboLab software Mindstorms NXT Education software Lego Digital Designer software Procedures Introduction: Big Ideas – Recognize a biological system and biologically inspired robotics Students will view RET Fellowship biologically inspired robot data and media Students will be broken into groups of 4 Students will investigate other biological systems and biologically inspired robotics Students will choose a biological system to represent robotically Students will record daily progress in their Engineering Notebook Procedures Implementation : Big Idea – Design, Construct and Program a robot Students will design a biologically inspired robot Students will construct a biologically inspired robot Students will program a biologically inspired robot Students will be encouraged to use Lego Digital Designer Students will be encouraged to use Lego NXT software Students will record daily progress in their Engineering Notebook Procedures Conclusion: Big Ideas –Summarize the design, construction and programming procedure Students will review their Engineering Notebook Students will summarize their procedure Students will identify their successes and failures in the process Time Line The time anticipated for students to fulfill the objectives of this unit is 8 days. Each class period is a block of time 89 minutes in duration. Introduction - 1 day Implementation - 6 days 2 days of research and design 2 days of robot construction 2 days of programming Conclusion – 1day Supplementary Materials Videos of Biological Systems Centipede Spider Fish Videos of Biologically Inspired Robots Centibot Spiderbot Robotic Fish Tale Robotic Fish Tail Fin Robo-Salamander Assessment of Students Students will be assessed on their Engineering Notebook, robot performance and unit summary. Evaluation The most important concept from this unit for students to demonstrate mastery is describing the procedure followed for designing, constructing and programming a biologically inspired robot. The lesson will be deemed successful if all students adequately describe a solid knowledge of this procedure and reflect upon it, pointing out both successes and failures.
