The workshops introduced new members to VEX Robotics and were also an opportunity for everyone to get to know each other. The workshops featured presentations on different types of lifts, drive-trains and electronics, giving the new members some basic information to build their very own …
Shifting X-Drive
With the release of VEX Sack Attack, many teams have begun to talk about using transmissions on their drivetrains. This is probably the best game ever for a shifting drive; speed is needed due to the large field and race for the easy to access sacks (by the goals), and torque is needed for the inevitable push battle that will …
Why is X-Drive Faster?
In this article, Oliver explains why x-drives have a higher effective gear ratio than tank drives. This seems unintuitive to a lot of people, but an X-drive robot has a higher maximum speed* than a tank drive robot with the same gear ratio. To best understand this, it helps if we consider what happens when the robot drives diagonally. Figure …
