Separate the robot construction on body - body and attachments. Attachments should be small, light and most importantly for winning the competitions they should be pinless. In this category we group tutorials, courses and materials for different attachments that have proved to be useful.
There are a few main challenges with box robots and in the following tutorial we would like to resolve them. Read on and let's see how we could do this.
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.
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.
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.
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.
Recap on the attachments, their purpose and how you should use them.
This one is very special- an attachment that could lock itself on purpose while working.
In this Episode, we create the next attachment for the box robot two. It is again a pinless attachment, attached to the frame that transfers the motion to a vertical axle.
Try to build the attachment following the instructions. Use it to actually solve a mission from any competition (like taking loops)
