Dominator is a compact LEGO Mindstorms EV3 Box robot from the family of the Roller Coaster and Kiddo box robots. Similar to the previous two robots, Dominator also can move its front part up, down, left and right. This robot also has the same length of movement as its two predecessors of this type - 8 LEGO pins on the side and up.

The difference is that Dominator has fewer parts and has a perfect center of weight that allows it to use large attachments and lift heavy objects without threatening its stability. The movement on the X and Y axes has the same gear ratio. The light sensors are attached to the movable part of the robot which enables it to both follow a line and recognize the color of various object with height lower than 7 LEGO units.

Here is an idea. What if a robot does not need attachments. What if there is one special attachment on the front that could do most of the work? Probably an attachment that allows you to move a lever in any direction.

This here is a Box Robot with X - Y axys plane. This robot doesn't need active attachments because it has X - Y table that do the job. Imagine that there is a plane on the front of the robot. With the rack mechanism you can move to any coordinates on this plane. 

We have a lot of ideas how to make it even better. We will try to release them in the next few versions.

Building instructions for a competition robot following the "Box robot" principle. The robot is built with LEGO Mindstorms EV3 and could be used at FLL and WRO.

This is a real competition robot with three light sensors and a gyro.

Note: This robot contains wheels that are from the NXT set.

This modification of the box robot contains large wheels. It was specially requested by you and we have it.

This robot was built by your request. It includes NXT large wheels. The Large LEGOO Mindstorms wheels will give you a faster robot, but be careful, because it will not be that accurate.

This LEGO Mindstorms EV3 robot chassis has the brick positioned vertically. Interesting idea that could be very useful.

Building instructions for a Light LEGO Mindstorms EV3 Competition Robot that could be used in LEGO Robotics competitions. Compared with previous versions of this robot, this one has a Gyro Sensor. 

For World Robotics Olympiad Ball Collection competitions we prepared an interesting Robot Base Chassis that could be extended with a container. The container contains the ping-pong ball. A mechanism collects them. This LEGO Mindstorms EV3 building instructions are for the chassis of the robot and were one of the versions from a series of robots.
