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.
In this Episode, we stop at the pinless attachments for the Box Robot 2 and especially for the constructing a frame. This frame is then used for further extending the robot with attachments.
In this tutorial, we would drive the scissors mechanism and there are a number of rules that we must follow
There were a few problems with the 40 teeth gears that we were using. Let's list some of them
Remember the passive/active attachment separation that we are making at FLLCasts.com. This applies for all the attachments and in this Episode, we are looking at how to use a passive attachment.
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.
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.
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 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.
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.
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".
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.
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.
Many teams have followed the same idea as the ELM team. To build a LEGO Mindstorms attachment for the robot and to lift the truck very lightly. In this way they could more the truck and place it in the special region. See what the ELM idea was.
Go to the missions model. Do the missions. You can then continue to the next mission or wait a few seconds at this FIRST LEGO League 2015 Trash Trek mission model and receive a few more points. Isn't it interesting. The ELM team has build a LEGO Mindstorms attachment for this robot. Let's see how it works.
There are many loops in the FIRST LEGO League competition. In this video we collect some of them by following the idea of the ELM team.
You can collect the car for scrap or repair it. The ELM teams decide to repair it. This requires them to place the engine in the car and it's very interesting to think about this problem.
This is a very interesting idea that is worth sharing with the rest of the teams and the ELM team has provided it to us. Check out how they drop a LEGO human at a specific place.
You need to pull. And also catch. You need a carabiner. We have done a number of videos on carabiners and this is one of the ideas for the FIRST LEGO League 2015 Trash Trek competition.
Many FLL competitions have a mission for demolition. You should always destroy something, but destroy it in a regulated manner and probably collect the destroyed mission model after that.
This is one of the very interesting attachments by the ELM team. It is using rubber bands and some rubber to precisely drop the chicken. Very interesting way. Check it out and try to learn from it.
In this video we discuss part of the pinless attachments build by the ELM team. Without pinless attachment it is nearly impossible to achieve a good score at the FIRST LEGO League competition.
Using a number of axles, beams and rubber bands we collect many loops at once. This is an important part of every competition, mostly of the FIRST LEGO League.
In this second part we continue with the next few tasks from the FIRST LEGO League (FLL) 2013 competition. Using the same rubber band attachment we lift the house and collect a few of the humans and cargoes.
Accomplishing many tasks with a single attachment for the FIRST LEGO League (FLL) 2013 competition. The attachments are using many rubber bands. What is interesting is that it collects/lift/triggers many things at the same time. This is how you could save time and parts during a competition.
This is the oldest and most classic problem in the field of robotics. Shaft in an opening. Basically robotics and in improvement of many of the actuators is about improving the solutions to such problems. Let's see how we ca do this using a mission model from the FIRST LEGO League (FLL) competition.
