With the shape of a box it is very easy to align this robot to different wall and to add very stable pinless attachments to it. The goal of the video is to discuss this feature of this particular robot construction.
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.
In this video we discuss how do we transfer power from the motors that are "inside the robot box" to the gear wheels that are "outside the robot box".
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.
This video discusses the fact the robot requires a few more parts that are available in the LEGO Mindstorms EV3 robotics sets. We have a number of other constructions that require less parts, but for this particular robot construction we have decided to go beyond the standard sets, cheaply buy a few more parts and build a whole box robot with them.
In this episode we look at the way this robot is balanced. A well-balanced robot could handle heavier attachments without losing track of its position on the robotics competition field.
In this video we look at the way this robot uses the LEGO Mindstorms EV3 motors. How are they attached and the what the rotation of the motor is transferred to the attachments.
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.
