Box Robot Two. With fewer parts and only one motor.
Here we start with a second box robot that we would like to build. It is in a way improvement to the first robot and we would take a look at its features.

EV3 is a robotics sets from LEGO Mindstorms. With EV3 you could build an infinite number of robots like Vehicles, Animals and Tanks. The set comes in two parts - base set (45544) and a resource set (45560). EV3 robots are very popular at LEGO Mindstorms Robotics Competitions
Here we start with a second box robot that we would like to build. It is in a way improvement to the first robot and we would take a look at its features.
We should how to build a frame that could hold the attachments for specific competition missions. This frame is added in a pinless manner. This means very fast and easy without any glitches of the pins.
This is the first Active Pinless Attachment for the Box competition robot. The attachment is placed on the top of the robot and is controlled by one of the motors.
One more example for an active attachment with a system of gear wheels. This time the system is constructed so that the attachment could lift heavy objects.
Without the use of any motor, you can still accomplish a number of missions using passive attachments. You can still pull/push on different levers using only a beam or two connected to the frame.
Second active pinless attachment for the robot construction. It is placed in the top/right corner of the robot and includes an interesting gear system for transferring the power. The attachment is suitable for complete rotations.
This is a third example for adding an active attachment. This third attachment is now connected to the wheel at the front of the robot. Again, the attachment could be easily extended.
In the video we improve on the robotics mechanism for pushing the different blocks out of the robot container. We continue from the previous video.
Next robot construction for holding and releasing balls from this container. In this video we discuss the improvements and how to use the chains to release one ball at a time.
Improving the construction for the World Robotics Olympiad missions. The improvement is in the position of the sensor and the size of the balls container.
