Spark Activity: Factoring in Friction

Friction can slow down or limit the movement of objects, but friction is also a useful tool when we need traction or gripping power. What we need to find is the right amount of friction for the current use. Do we need wheels and gears that can turn freely on their axes? Do we need wheels that can grip the road to move a robot forward or up a hill? Sometimes we need to both reduce and increase friction! Using simple household items like a small box, cardboard, paper clips, binder clips, clothespins, straws, different kinds of tape, and toy wheels, explore movement and friction by testing a small box on a number of surfaces, looking at static friction and sliding friction. Test rolling friction by adding wheels (cylinders) or rollers as a way to overcome the overall friction of an item. Plan and design a vehicle to maximize its ability to coast based on the effects of friction. You will also consider constraints of capacity, efficiency, complexity, and costs in the design. You will build or assemble a complex “clipmobile” considering and addressing effects of friction and design constraints. You’ll find the answers yourself!

Project Manuals & Exhibit Requirements

Youth Enrolled in Robotics 1, 2, and 3 should use The Robotics 1 with EV3 and EV3NMore ONLY if they have access to an EV3 Robotics kit. For youth looking to use the new Lego Mindstorms Inventor Kits or the SPIKE kits, please refer to the online resources listed below for guidance. For youth competing in their respective county fair, and potentially the State Fair, youth will be required to document their experience in a Robotics Notebook, and select/demonstrate one of the selected tasks used in the State Robotics Challenge. The challenge details will be released in late October with the Robotics Notebook template.  

  • Robotics 1 with EV3
  • Robotics 2 with EV3 N More
  • Robotics 3: with EV3 N More
  • Junk Drawer Level 1: Give Robots a Hand
  • Junk Drawer Level 2: Robots on the Move
  • Junk Drawer Level 3: Mechatronics
  • Junk Drawer: Youth Notebook

Purchase the manuals above on the Shop Illinois 4-H Store
