We will demonstrate the common mistakes students make when building a robot.
This is a tutorial with 10 runs - 5 of them are slow and 5 of them are fast and we measure how accurate the robot is each time. How consistent is it? Can it arrive consistently on a specific location on the field without the use of the sensors? The quick answer is - No, it can not. But let's see it life
Continuing from the last tutorial, we demonstrate the consistency and reliability of the robot when we don't user sensors. The result is pretty obvious - the robot is NOT consistent and reliable. It just makes a lot of mistakes
Without the use of the sensors, make sure that you are at least using "set movement acceleration to slow". In this tutorial we will demonstrate why and how this helps us improve the accuracy and consistency of the robot.
This is a 10 runs tutorial that demonstrates how the accuracy of the robot improves when we use slow acceleration vs fast or default acceleration. Note that the improvement is small. This is not an accurate and consistent robot. No. This is a robot that is all but accurate or consistent. It does not use sensors and you should use sensors. But it is a teaching/demonstration moment for everybody to seen what is it that you can expect if you don't use sensors.
We will build the EasyBot quick robot and will explain how to follow building instructions.
In this video we discuss how do we transfer power from the motors that are "inside the robot box" to the gear wheels that are "outside the robot box".
Now we have to program the robot. The steps that we will cover are starting the software, writing a program and downloading it to the robot.
We are working on the World Robotics Olympiad (WRO) 2013 competition and its elementary part. The series will introduce three different concepts and this would be Arrays, Menus and Counting different lines. In the video you will see the robot working as it is in the final stage.
There are some things to be careful about when your students work with the brick.
This second part continues with importing two previously developed in Episode 53 blocks into our program. With them we can for align to lines. We program the robot to align to the cross line and start following it.
Robotics Game of Life – that’s the name of our new scientific journey. We are organizing a 14-sessions course (1 session weekly). The idea of the course is to develop a solution to the Conway Game of Life where the robots would actually play the game. Students will construct the robots by instructions and lots of imagination. Initial programs will be provided by us and modified by students.
In this lesson we will program our robot to display emotions!
In this video, we introduce two pieces: beam with pins and the angular beam with pins
This is where the confusion really comes. We are keeping the robot orientation straight while the robot moves, but at the end the, robot is not at the fiinal location that we would like it to be. The robot is still about 2-3 centimeters away after moving for about a meter.
