In a competition environment like the FIRST LEGO League (FLL) or World Robotics Olympiad (WRO) the color sensor is more than useful. It makes positioning on the field quite easy and precise.
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.
We continue from part 4 where we made a controlled experiment to transfer power from a Mindstorms motor to the rear wheels. The construction was too complex and inefficient and in this video lesson we are improving it by lowering the differential and removing all gear wheels from this LEGO Mindstorms EV3 Competition robot.
With this attachment we just share an idea. The attachment was build by an FLL team called Brother in Arms and they needed a way to turn two axles in different direction, one at a time. The attachment was not used in the final robot design and construction, but presents a nice idea.
This video lesson is a revised version of Episode #1. Matt Gipson requested it in a comment. Using the EV3-G software we have developed a very simple program for following a line with two LEGO MINDSTORMS color/light sensors.
Here is the task for adding a beam on both sides of every gear wheel in your attachment.
The task in this tutorial is to execute the program 10 times and to do it yourself. If you have your attachment then use it. If you have our attachment then use it. But execute the program 10 times and make sure that it works.
The robot works on the field and decodes the different colours that represent the rows and the columns.
A robot attachment placed on the right side of the LEGO Mindstorms Box robot chassis. It uses two gear wheel to move a level. The level could collect things.
After the great success of the previous two Box Robots Courses (Box Robot 1 and Box Robot 2) we are improving the construction even further showing one more way to build Box Robots and to resolve some of the challenges that we all had with the previous robots.
Of course attachments are a great topic of the robots. We show the general way in which one is to build attachments with the Knob Wheels and Gear Wheels mechanisms.
This program lets the robot Safe be opened with a password, and demonstrates how passwords can be stolen.
A robot that can be an ATM or smart lock with color code. The programs pull in and push out the color card and play sounds if the colors are in correct order. When the order is incorrect, you hear an error sound.
The robot takes place in lesson 7 of level 3.0 Security Systems.
Building instruction for the power switch mission model. The model is used in the Power supply mission of FLLCasts Off-season Challenge 2019.
Building instructions for the container mission models. The models are used in the Automated delivery mission of FLLCasts Off-season Challenge 2019.
This module is meant to be used in EV3 Kinesthetic and Memory Game and is attached to the base of the robot. This is the simplest module for constructing and programming. At the bottom, a channel is left for the cable to pass through.
This is a module that is made to look like a polar bear head, but really it could be used for many animals. It uses a medium motor to bite and an ultrasonic sensor for eyes. We have labeled it a polar bear head, because it is used in Polar Bear - LEGO Mindstorms EV3 Robot that looks like a polar bear.
This module is made to look like a head of a ram made with LEGO Mindstorms EV3. It uses an ultrasonic sensor, which points down as if it is going to attack, as the eyes of the head. It can be combined with other modules to create the perfect ram robot!
During a competition a team of students had to build a robot that looks like a musician. This construction in front of the robot is a Trompet and it looks like Ane is playing some music. If you play music on the phone on the side it is really funny to watch it play.
