The Challenge: Putting it All Together

Manufacturing makes everything we touch, use, eat, buy and sell. Because of modern manufacturing processes we can make one or one million items with consistent quality. 

This challenge focuses on the key techniques of manufacturing. The challenge is designed so a few well-designed mechanisms can be used on the entire table. You will be moving elements from the supplier, placing them in storage, moving them to the assembly area for completion, packaging the items, and transporting them to the customer. Plus there’s a bonus challenge that will spin your mind!
