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.
This third way of positioning the LEGO Mindstorms EV3 motors on the robot seems to be the most productive with the most advantages. We have named it "correct", but we completely understand there might be other even more efficient ways to position the motors on the robot.
It has been a long road with the last 8 BigDaddy competition robots video tutorials, but we finally arrived at the Differential Lock.
Pinless attachments are smart and quick and could make a big differences between two robot constructions. In this video we are sharing a nice idea for a pinless attachment placed below the robot.
In Episode 58 we introduced you to an LEGO Mindstorms EV3 Modular robot. Mic Lowne wrote to us and had that robot remade, because it used too many blue lego pins and could not be build using one EV3 kit.
How can you accumulate some energy in an LEGO Mindstorms EV3 construction an use this energy at a later moment? How does a Flywheel work, why is it important and what is the purpose? What is energy, inertial moment and angular velocity. These are just some of the questions we would answer in this series on Physics and LEGO Mindstorms.
In the video we reach a conclusion. We have energy accumulated and to keep the system turning we need about 1J of energy each second to keep it turning.
Counting lines and stopping on the third is the subject of this video. It is important to know how to do this in order to conduct more than one experiment in STEM classes (if we consider that each line is an experiment)
This tutorial is about how to follow a wall with an ultrasonic sensor. The example is with a border from a FIRST LEGO League (FLL) competition, but could also easily be applied to other competitions and problems.
Continuing with the Proportional algorithm for following lines. Smooth and stable this is the first part of the PID.
Last part of the series. The final touch of the program makes sure that it works and is following the line with the LEGO Mindstorms EV3 Color Sensor in a smooth and fast way.
How do you detect a cross-section and move from following the main line to following the crossing line. In this series of video tutorials we are starting with a very simple solution that could work in most of the cases. It is especially useful for the FIRST LEGO League Trash Trek competition where there is such a section.
Given the large number of gear wheels and axles in each EV3 and NXT sets there are many possibilities for building gear mechanisms. We are developing something like a gear box that has different axles that could all turn in different directions.
Five different robot chassis. This is the goal of the series. To present ideas for different design of the robots and especially the robot bases. If the base is stable and balanced, then in could easily be extended. Let's start with the most simple of the five.
