Following lines, detecting colors, responding to light. It is still far from "seeing", but the LEGO Mindstorms EV3 & NXT sensors could be very useful when used properly.
The Sports Utility Vehicle box robot is the new marvelous box robot that we've created. It is designed for teams that would like to learn how to build balanced, stable and working robot chassis following our box principle. It is smaller and easier to build than box robot 1 and it is more simple than box robot 2.
The main advantages of this robot compared to previous box robots are
- motors in the right direction, so when rotating the motor forward, the robot moves forward.
- it is much easier to attach attachments. There are 4 different gears on which you could attach attachments.
- it has a large clearance - which means that it could move over obstacles.
Of course, it has a Gyro and two Color Sensors. Not only that, but we have all the cables shown in the construction.
The SUV Box robot is design to be used with a Gyro sensor and two Color Sensors for alignment. It is not working well for following lines as the sensors are very high and they are very high to allow for high clearance of the chassis. If you need to follow lines we recommend the Dominator X-Y robot

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.

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 is the robot that we use to demonstrate a solution for competition. This is a Post season solution. We never release any solutions during the season as this will have a negative impact on the competition. But after the competition we try to make a review and to see how we could have accomplish it. Our goal is to be better for next year.
This robot is quite powerful. The attachment mechanism on the front is one of a kind as it can do several things with a single motor: it can lift, it can unlock, it can grab. All of this thanks to the unique mechanism of gears
This is the robot that we use to demonstrate a solution for the World Robot Olympiad 2021 Junior competition. This is a Post season solution. We never release any solutions during the season as this will have a negative impact on the competition.
We started with this robot and it has a few good ideas. It can collect two cars at the same time. We later decided to go for a more powerful robot. Check out WRO 2021 Junior: Slaimi - a post season WRO competition solution robot
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 is an example of a robot for Sumo Robotics competitions. Specifically for RoboteX challenge. As most of the Sumo competitions have specific requirements for the robot size this one follows the 15cm x 15cm requirements.
Sumo competitions could be quite fun and interesting as the goal is to push the other robot outside of the ring.
This incredibly compact SPIKE Prime Box Robot is made for competitions like FIRST LEGO League (FLL) and World Robotics Olympiad (WRO). Whakatae (from Maori's word "whakataetae", which means "competitive") is long 17 LEGO units and is with a width of 15 LEGO units. In front of the wheels it has two color sensors which it uses to align. Whakatae also has two Large motors for moving and has two medium motors for attachments!
It's has "V2" in its name, because it's the second version of Whakatae - LEGO Education SPIKE Prime Competition Box robot. The difference between the two is that the first one can be built with only a Large Motor and a Color sensor in addition to the Base set, while this one needs an additional ball bearing. This provides this robot with a lot more stability and can be seen as a true upgrade to the first version.
This LEGO Mindstorms EV3 robot chassis has the brick positioned vertically. Interesting idea that could be very useful.
