Course Description

This course covers robotic systems, engineering design, and mechanics. Students will learn to use the engineering design process to define a problem to be solved, establish requirements and specifications, and brainstorm solutions. During Lab, students will build robotic mechanisms, assemble robots according to instructions, and learn to solder. The course culminates with students prototyping the mechanical mechanisms for a robot of their design. Formerly known as ELEC A101. ADVISORY: ELEC A100 or concurrent enrollment. Transfer Credit: CSU.

Course Level Student Learning Outcome(s)

Lab Content

Safety and Lab Familiarization Lab Procedures Tools Equipment Supplies Electromagnet Project Students use motor wire and a core to build a simple electromagnet. Students use benchtop power supplies to supply current. DC Motor Project Students use motor wire and a permanent magnet to construct a simple DC Motor. Soldering PCB Component Soldering- Kit Joining wire by soldering and heat-shrinking Winch Project Students build a winch to use a small motor to lift a 20lb weight. Report- Sketch of design Calculation of Gear Ratio Calculation of Torque at each stage Calculation of motor current/torque Theoretical vs. Actual Power- Calculate Actual Efficiency Vehicle Project Students assemble a simple robot from a kit. Instructions are provided and students assemble the robot to exact specifications. Students establish a wireless connection between the robot and a controller for verification of robot functions. Students demonstrate proper cable management for moving vehicles- Strain relief Proper use of zip ties vs. electrical tape Cable protection and avoidance of pinch points Group Capstone Project Students progress through the engineering design process in small groups to build a robot to solve a specific need. Students produce documentation throughout the process and implement project management strategies learned in lecture. Students culminate by prototyping the mechanical mechanisms and testing their designs. This project is intended to be primarily a mechanical design project, with minimal time spent on controls and automation. Report- Working in groups, students produce a final report documenting all steps of their design process.

Instructional Techniques

Lecture Detailed whiteboard lectures with opportunity for student engagement. Independent in-class problem solving assignments with immediate review. Group based in-class problem solving assignments with immediate review. In-class review of previously assigned homework. Discussion of media provided and assigned via LMS. Review of material prior to exams. Lab Students complete projects individually and as groups.  Lab projects reinforce lecture topics and are paced to coincide or lag the lecture content. Lab projects generate content that students use to generate reports and documentation, enhancing writing and critical thinking skills.

Reading Assignments

Students will spend approximately 2 hours reading from the textbook and instructor material provided via LMS.

Writing Assignments

Students will spend approximately 1 hour per week on writing assignments, including: Keep a journal of chronological notes taken during research, lecture, and laboratory experience. Author a technical report for each project written to industry standards for technical reports.

Out-of-class Assignments

Students will spend approximately 3 hours per week on out-of-class assignments, including: Researching topics as assigned. Preparing technical documents prior to laboratory projects. Completing technical reports after each project. Maintaining a portfolio of projects throughout the semester.

Demonstration of Critical Thinking

Students execute the design of a robot using the engineering design process. Students work individually and in groups to solve challenges presented in a project based form. Quizzes administered at the end of each topic to demonstrate mastery of the specific objective. Midterm and final exam administered to test ability to retain problem solving skills.
