This activity pairs with the Programless Drivetrain Build Activity to introduce the challenge of utilizing gears to modify the drivetrain’s speed and torque. Students will have to adjust their gearing to accomplish their goal as the servo’s output cannot be modified!
Students will take advantage of the extrusion frame to slide their hex shafts, wheels, servo, and gears into different places to adjust their gearing. Additional hex shafts can be added to expand the gear train.
This activity includes two challenge options: a short version (SV) and a longer version (LV)
