Improving FLL Robot Game. Task. Lift your robot with 40 teeth gear wheels.
Build a similar mechanism to this one. Similar, but for your robot. This is the task for you. Try, give yourself half and hour or even an hour.

Build a similar mechanism to this one. Similar, but for your robot. This is the task for you. Try, give yourself half and hour or even an hour.
How to align the wheels and how much should you push for this solution?
There were a few problems with the 40 teeth gears that we were using. Let's list some of them
Here is our solution for preventing torsion and bending of the LEGO Mindstorms EV3 axles.
Building instructions for a LEGO Mindstorms EV3 Active attachment for changing gear orientations
Calculate the number of rotations you have to do with the motor to rotate the final small 8 teeth driving gear wheel to 1.25 rotations?
What should you do as a teacher when the students are calculating the gear ratios and number of needed rotations?
Building instructions for a robot for the World Robotics Olympiad Sputnik competition. This is the light version without the lift at the top.
"What is the light in the room?" - should it even matter. You can use one program for all lighting conditions by calibrating the color/light sensor of the LEGO Mindstorms EV3/NXT robots.
Building instructions for a LEGO Mindstorms Catapult Motor and Touch Sensor that are used for triggers for firing objects
This LEGO Mindstorms Attachment has three gears, one frame and two axles. The goal of the attachment is to use the gears to change the direction in which the motion is transferred.
A similar LEGO attachment the previous once, but this one is with a different gear ratio. Again using a frame, two axles and two gears you can change the direction of the motion.
These are building instructions for a LEGO Mindstorms EV3 demonstration model. In the tutorial, we are using it to demonstrate the working and relations of LEGO Gears.
One LEGO gear is powering two LEGO Gears and at the end, from one motor we rotate two axles in opposite directions. Follow the building instructions.
Part three of the Catapult series is about loading the catapult automatically. We use a gear system with a medium complexity along with a very interesting "clutch" developed with parts entirely from the LEGO Mindstorms NXT kits. As a result, at the end of the video, the Catapult automatically loads and fires.
This was an idea. You would we demonstration a multi-axle power and rotation transmitting box. Well, here it is. Build it. Start it. And see how the power from the motor is transmitted through different axles. The lever will demonstrate it.
This is the initial construction of a catapult. The base on which we will place the rest of the robot. The goal of this construction is to give the catapult the ability to rotate.
If you take a look at the videos for this attachment you will see a nice idea on taking the track and the ambulance. These two vehicles from the FIRST LEGO League 2013 competition had to be collected and returned back to base.
