Virtual Robotics Toolkit (VAT) was developed by Cogmation Robotics. It develops simulation software that enables users to control robotics systems. You might ask why you should use a virtual robotics environment when you have a real EV3 robot at hand for playing, but there are situations where your robot is placed somewhere else (for example, …

In my previous posts, I analyzed some models used in WRO 2018, 2019 and 2020. In this post, I will analyze several models used in WRO 2017, elementary age group. The game description, rules and scoring could be found at WRO website: https://wro-association.org/competition/previous-challenges Model 1 https://www.youtube.com/watch?v=bP6VaBNL3wQ?rel=0 This model uses two touch sensors to control panel-like …

In my previous posts, I analyzed several models used in WRO 2020 and WRO 2019, elementary age groups. Today, I would like to introduce two models for WRO 2018 competition and compare their advantages and disadvantages. The game description, rules and scoring could be found at WRO website: https://wro-association.org/competition/previous-challenges Model 1 https://www.youtube.com/watch?v=UICkrGr7mHc?rel=0 This model has …

In my previous post, I introduced how to use stalling detection method to avoid motor stalling or identifying the existence of obstacles. That model is programmed with LEGO programming blocks. In this post, I will introduce how to use LEGO Micro Python 2.0 to do stalling detection and what are some issues in implementing this. …

In previous posts, I have explained how to make the EV3 vehicle follow a line and square up with a line or wall. In this post, I would like to explain another important technique: how to make the EV3 robot recognize stalling status and then adjust itself to end stalling in time. What is Stalling? …
In the previous post, I introduced how to make LEGO EV3 follow a line by using proportional control, or more advanced PID control method. I also explained how to square up with a wall. In the real scenario, the robot also needs to square up with a line. Unlike squaring up with wall, there is …
In my previous post, I once analyzed an interesting game - Grids the Puzzle Game. The author uses lists to store the data, update data and check data, which is a good example of list usage. In this post, I will explain another way to implement the same functionality and then compare the difference of …

In my previous post, I analyzed an interesting LEGO WeDo 2.0 model - a helicopter model. It uses one motor to drive three moving components - the top propeller, the rear propeller and its two wheels. In this post, I will analyze another helicopter model which uses one motor to drive two components - a …
