One of the interesting things in this sequence of videos is the program. The program detects when the system has reached the maximum speed and then stops the motor from rotating. We detect this with the EV3-G software
How to organize the different robots and group of students when working on lifting the robot.
In the previous video, we found the correct answer for our task and it is 18.75, or is it?
Connect the attachment to the box robot and find the correct number of rotations of the middle motor that would bring the robot up and forward and would attach it to the mission model.
For the FIRST LEGO League 2016-2017 Animal Allies we prepared an attachment for lifting the robot. The idea of the attachment is to show how you could lift the whole robot with a system of gear wheels, levers, and scissors constructions.
Built mainly from LEGO Mindstorms EV3 parts but could probably be constructed from NXT sets.
We continue from part 3 where we finished part of the 'rear'. Power is transfered from a motor to the wheels but having about 16 gear wheels makes it more than complex for this LEGO Mindstorms EV3 Competition robot.
Here we continue examining FLL 2014 World Class missions. We show different ways, for putting the insert in place as well as taking the loop from the robotics arm. Some of them are quite specific, which reminds us, that you need to think out of the box, while solving the missions.
We are describing the Warm gear in this video. This worm gear does most of the magic of controlling how the different gear wheels move on the different axles.
Another example for a quick pinless attachment build with LEGO Mindstorms EV3 robots.
Building instructions for a Light LEGO Mindstorms EV3 Competition Robot that could be used in LEGO Robotics competitions
"How to use the LEGO robots to facilitate the learning of robotics by my student at home" or simply put - "what to build now?"
After enrolling in this course we will send you a few (1-2-3) emails each month with a title "A robot a 'day'". Each email contains a robot building instructions and/or video tutorials and/or tasks that should be accomplished. After a task is accomplished we might sometimes ask for a video or picture.
This process gives a structure of the learning process where you can learn from the content. The student participates in a course, but from home and on the schedule that you decide.
This one is also fast. It has assistant wheels, but only to keep the balance. It is built with LEGO Mindstorms EV3 sets with the use of one additional Medium Motor.
Join the course A robot a "day" keeps the questions awake where we will further discuss the motors, how to build them and what tasks to accomplish with them.
Building instructions for the most simple grabber using just one Large EV3 LEGO motor. It has one static lever and one active lever.
We got the speed of rotations of the motor in Radians per second. Let's calculate the value for the speed of the whole system. We calculate that the wheels are rotating with 375 radians per second. Which is impressive and quite fast for this system. From this speed, knowing the inertia mass we can calculate how much energy is the system accumulating.
Time flies when you are having fun! Luckily, we have this robot to keep us on top of our schedule. Tempus is a robot that is made to look like a clock. The two hands are each connected to a motor and are positioned between the two motors. This makes the robot simple to build and effective in showing how a clock works.
