 +===== VEX Gear Types ===== 
 +VEX gears come in 2 types: standard/​normal strength and high-strength. As shown in the diagram below, high-strength gears have number of features that make them an improvement over the "​standard"​ (thinner) gears. 
 +{{ :​robot_design:​gears-normal-vs-high.jpg?​nolink&​600 |Normal vs. High-Strength gears}} 
 +  * High-strength gears are about **twice as thick** as standard gears, meaning they are unlikely to crack, and the teeth are less likely to break off. (Everything does have its limits, however; high-strength gears do not come with magic included.) 
 +  * The center of the high-strength gear, out of the box, is just a big square hole, and the user chooses which of 2 inserts to put in the middle (or no insert, in the case of high-strength shafts): 
 +    * one insert (not shown) makes the center a **round hole** in which a shaft can spin freely; this is useful for idler gears whose shafts are not driving a mechanism, but rather just there to hold a gear; 
 +    * the other, shown in the image above, is a **metal insert** that has a square hole that a standard shaft then fits through. These metal inserts are really snug; sometimes they need to be wedged in with a screwdriver,​ pliers, etc., but once they'​re in, they'​re not going anywhere, and they'​re not going to strip. One insert goes on each face of the gear. 
 +  * The smallest (12-tooth) gear is **solid metal**, and is not going to crack, even under duress.
  
 +For a **competition robot, high-strength gears are recommended** for their reliability and durability.
