2. Available at: www.etcurr.com Lesson 4.1, Build a Conveyor Feeder Build a Conveyor Feeder  Performance Objective: Given VEX parts build a conveyor feeder that can move a block six inches horizontally and then 12 inches vertically.  Enabling Objectives:  identify the parts of a conveyor feeder  explain the role each part plays in a conveyor system  explain the purpose of a conveyor feeder

3. Available at: www.etcurr.com Lesson 4.1, Build a Conveyor Feeder Conveyor Feeder  In VEX competitions it may be necessary to pick up an object and move that object horizontally and/or vertically  For example, VEX Elevation

5. Available at: www.etcurr.com Lesson 4.1, Build a Conveyor Feeder Solution  One solution for this task was to build a conveyor feeder using a tank tread kit  A tank tread kits contains: tread links, tank tread drive/idler wheels, double bogie wheel assemblies, single bogie wheel assemblies

6. Available at: www.etcurr.com Lesson 4.1, Build a Conveyor Feeder Tank Tread Kit  Tank Treads are in contact with the object being moved with the conveyor

7. Available at: www.etcurr.com Lesson 4.1, Build a Conveyor Feeder Drive/Idler Wheels  The drive wheels are connected to the motors and are used to drive the tank treads  These wheels may be used as idler wheels if the tank tread is too loose

8. Available at: www.etcurr.com Lesson 4.1, Build a Conveyor Feeder Bogie Wheel Assemblies  Bogie wheel assemblies are used to give the tank tread system its shape  The double bogie wheel assembly is used to support the tank treads while moving across a surface

10. Available at: www.etcurr.com Lesson 4.1, Build a Conveyor Feeder Conveyor Feeder  The conveyor feeder may not require all of the parts necessary to drive a tank robot  It may be beneficial to have the top and bottom of the tread system to be parallel and not trapezoidal like to example shown on the previous slide

11. Available at: www.etcurr.com Lesson 4.1, Build a Conveyor Feeder Conveyor Feeder  To use the tank tread kit as a conveyor feeder to move a block, it may be necessary to have two tread systems parallel so the block is placed in between the two treads  When both treads move, the block will be moved as well and not rotate
