Looking at the field we must first think of a strategy of solving this line following problem. There are rules that the robot must follow and these rules should be programmed in the robot.
In this episode we build a reusable attachment for a LEGO Mindstorms EV3 robot that changes gears orientation and direction. It is one of the most useful attachments that you could use to move levers up/down and right/left. Adding the attachment on the robot takes 2-3 seconds and shows a very useful general principle of how to build reusable attachments.
We are programming this strange construction to move in a square. This is a basic task, but it is worth doing for a robot with motors placed in different directions.
After we have introduced a menu in the previous video, this video focuses on storing the values in an array. It presents a basic use of arrays.
It's inevitable. While following this gapped line we would reach a gap. The robot must somehow understand that there is a gap and must make a decision on what to do. For detecting the gap we use the Rotation Sensor. Not the most popular, but very convenient in many cases. Check out the video.
Modification of the EV3 Competition Robot Full with light sensors attached to the front
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.
Built from LEGO Mindstorms EV3 parts.
The first of a series of attachments that we add to a World Robotics Olympiad LEGO Mindstorms Robot. The attachment is an example for collecting ping-balls. The robot and the attachment are in the same construction. The attachment is a base for a container that could be extended.
We want students to be able to easily find the parts and to put the parts back in the designated compartments.
Files are printed on both sides of 160-gram sheet of paper A3 format.
The sorting sheet is designed to fit in the cover of the box. To gather in the lid, the excess parts of the printed sheet must be cut off the markers on the front of the sheet.
To extend the life of the sheets, you can laminate them either with a "laminate matte" or a simple laminate. The disadvantage of the simple laminate is that there is a lot of gloss. The disadvantage of laminate matte is that it has to be sealed with a clear PVA C-200 adhesive to prevent it from opening over time.
We recommend printing doublesided and turning over the "short edge", like a book. If you decide, you may flip the printed result over the long side. Both options are available at you local print center.
No need for all attachments to be powered by motors and to include gears. It's sometimes possible to use a simple robot attachment to collect objects. Such attachments we call passive and this one is an example for the Box Robot Chassis.
Build with LEGO Mindstorms EV3
Implement a program for stopping at a black line with the blocks containing the implementation details for the InitArray, Calibration and Getting the calibrated result.
Following the Advance Light/Color sensors calibration for a minimum value for a single sensor tutorial, in this one, we continue with finding the maximum value detected by a sensor and storing this value in an array.
Building instructions for a LEGO Mindstorms EV3 robot that could be completed in about 3 minutes. Could you do it? Try it.
We use this robot when we need something very fast for a demonstration or a small competition. Just attach the motors and you are ready. It is fast.
NXT-G program for running the Catapult robot build from the LEGO Mindstorms NXT robotics set
We've recently received a number of question on how could the SUV box robot be charged. The answer is simple - you detach the back pane. The question and topic of detaching modules from a robot and attaching them again is really interesting and powerfull and yet not very often implemented in many robots.
This is a program for the Sebastian crab robot. It makes the robot walk, but also keeps track of where its legs are. It makes those who overrun the others to stop and wait for them.
The M08. AEROBIC EXERCISE is one of the very common types of mission in FIRST LEGO League robotics competitions. I think this pattern of missions was first introduced with the growing abilities of the participating students that were constantly reaching the maximum number of points. So the competition introduced mission that require a lot of time - 20-30 seconds, are time consuming and are complex. They requires a lot of moves. This here is a video tutorial on how it could be accomplished
This is the attachment of Team "Nightbeast", with which they do:
M11–Escape Velocity and M13–Observatory
The Observatory result depends on the model. Sometimes the pointer is in the orange area otherwise in the white area.
This is a module that looks like a fish's head. It uses a touch sensor for a mouth and is otherwise purely cosmetic. The module is used in Piscis - a LEGO Mindstorms EV3 Fish robot.
