SolidProfessor Pre-Labs

Each lab session has an associated Pre-Lab assignment that consists of a specified set of material from the SolidProfessor site. You are expected to complete all of the Pre-Lab with a focus on learning and becoming competent in the concepts and techniques that are introduced in the video tutorials. Each Pre-lab includes a set of exercises that you are expected to complete. These exercises will not be collected.

Most Pre-labs will have supplemental materials in the form of extra modeling suggestions that you can use to gain more practice in the concepts covered in the Pre-lab. These materials will be located under the Assignment Add-ons tab in the Solid Professor interface.

The Pre-lab grade is based upon your completion of the Pre-lab. The percentage of each Pre-lab that is completed is available to the course instructors through a SolidProfessor reporting tool. The Pre-lab grade is “all or nothing” – you must complete the entire Pre-lab assignment prior to your weekly lab meeting for you to receive any credit for this work.

The Pre-labs will include materials from the SolidProfessor SolidWorks 2013 Course List the primary modules to be covered are:

·         2013 SolidWorks 101 – Academic

·         2013 Core Concepts

·         2013 Drawings

·         2013 Advanced Parts

Arduino Pre-Labs

The Sparkfun Inventor’s kit includes a Guide book that contains 15 exercises. Prior to each lab session you will be assigned one or more of these exercises to complete. You will also be assigned a number of video tutorials to watch. This Pre-lab information will be listed on the course blog.

Lab Quizzes

Each lab session will begin with a short quiz that allows you to demonstrate competency in the concepts and techniques that have been introduced in the Pre-Lab. This will typically include both a SolidWorks exercise and some questions that cover the Arduino topics.

 

 

 

Mini-Projects

Most lab sessions will introduce mini-projects that are meant to provide you with a means to expand your ability to both create solid models and use a microcontroller. These projects will also provide you with the ability to create a physical object using a 3D printer. Some of these mini-projects will be individual efforts and some will be collaborative. 

Group Design Project

The group design project is an opportunity to work in a team environment to design, build and test a device. The device will be designed in SolidWorks, contain parts that have been 3D printed (and possibly laser-cut) and be designed to interact with its environment via sensors and actuators.
