a hex mover coupled to the input hex, wherein the hex mover includes following teeth and driving teeth; a following ring gear in contact with the following teeth; a driving ring gear in contact with the driving teeth; one or more gear pinions in contact with the following ring gear and the driving ring gear; one or more gear rods configured to support the one or more gear pinions; and a gear holder coupled to the one or more gear rods. ## Claims ### Claim 1 A rotation converter configured to convert an alternative clockwise-counterclockwise rotation to a single rotation direction, comprising: a hex shaft comprising an input hex, an output hex, and a gear contact, wherein the input hex and output hex are separated by the gear contact; a hex mover coupled to the input hex, wherein the hex mover comprises following teeth and driving teeth; a following ring gear in contact with the following teeth; a driving ring gear in contact with the driving teeth; one or more gear pinions in contact with the following ring gear and the driving ring gear; one or more gear rods configured to support the one or more gear pinions; and a gear holder coupled to the one or more gear rods. ### Claim 2 (depends on 1) The rotation converter of claim 1, wherein the driving ring gear is configured to be coupled to a rotation input; the driving ring gear is configured to rotate in a clockwise direction in response to the rotation input rotating in the clockwise direction; and the driving ring gear is configured to rotate in a counterclockwise direction in response to the rotation input rotating in the counterclockwise direction. ### Claim 3 (depends on 2) The rotation converter of claim 2, wherein the driving gear comprises driving gear inner teeth. ### Claim 4 (depends on 3) The rotation converter of claim 3, wherein the driving gear inner teeth are configured to engage with the driving teeth when the driving ring gear rotates in the clockwise direction, causing the hex mover to rotate in the clockwise direction; and the driving gear inner teeth are configured to disengage with the driving teeth when the driving ring gear rotates in the counterclockwise direction. ### Claim 5 (depends on 2) The rotation converter of claim 2, wherein the following ring gear comprises following gear inner teeth. ### Claim 6 (depends on 5) The rotation converter of claim 5, wherein the following gear inner teeth are configured to engage with the hex mover following teeth when the driving ring gear rotates in the counterclockwise direction, causing the hex mover to rotate in the clockwise direction; and the following gear inner teeth are configured to disengage with the hex mover following teeth when the driving ring gear rotates in the clockwise direction. ### Claim 7 (depends on 2) The rotation converter of claim 2, wherein the hex mover is pushed towards the driving ring gear when the driving ring gear rotates in the clockwise direction; and the hex mover is pushed towards the following ring gear when the driving ring gear rotates in the counterclockwise direction. ### Claim 8 (depends on 1) The rotation converter of claim 1, wherein gear teeth of the one or more gear pinions are in contact with driving gear outer teeth of the driving ring gear and following gear outer teeth of the following ring gear. ### Claim 9 (depends on 8) The rotation converter of claim 8, wherein the hex mover and the hex shaft are configured to rotate in a single rotation direction. ### Claim 10 (depends on 9) The rotation converter of claim 9, wherein a rotation direction of the following ring gear is opposite to a rotation direction of the driving ring gear. ### Claim 11 (depends on 1) The rotation converter of claim 1, wherein the driving ring gear is configured to rotate the one or more gear pinions, and the one or more gear pinions are configured to rotate the following ring gear. ### Claim 12 (depends on 1) The rotation converter of claim 1, wherein the output hex is configured to be coupled to a drill bit connector. ### Claim 13 (depends on 1) The rotation converter of claim 1, wherein the gear contact comprises a section of the hex shaft having a smooth outer surface such that the hex shaft is configured to rotate independently from the following ring gear. ### Claim 14 (depends on 1) The rotation converter of claim 1, wherein the hex shaft rotates in a same rotation direction as the hex mover. ### Claim 15 (depends on 1) The rotation converter of claim 1, wherein the one or more gear rods are separated from the hex mover such that a movement of the hex mover is independent from a movement of the one or more gear rods. ### Claim 16 (depends on 1) The rotation converter of claim 1, wherein the driving ring gear is parallel to the following ring gear.
