The robot is not at the right position at the end of the straight movement?
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.

Importance of the wheels and tires on the LEGO Mindstorms robot movement
DIfferent wheels and tires will result in different behaviour of the robot. That is actually pretty common sense. The real question is what is the influence. Would the robot make smaller deviations if it has smaller wheels or it will make larger deviations? The tires could also be quite dirty or brand new. Or the wheels could be attached in different ways.

Starting leJOS USB transfer sample on Windows XP (Part 1)
In this episode I would like to show you how to enable the communication between the computer and the NXT brick, through the USB and using the leJOS project. Starting leJOS on Windows is pretty easy. But starting the samples and achieving the communication is the actual problem.

Python with LEGO Mindstorms EV3 - Level 2
In the second level of Python for EV3 robots, students learn in-depth the touch sensor. The sensor is used as an input device for manual control of machines, as well as a sensor for autonomous robots. In a pair of lessons, students build a control panel for the grabber and the movement of a crane. Programming wise, students learn how to fork code with "if-else" constructions, how to create conditional and forever loops with "while" and how to negate conditions with "not" operator. In the end of the lesson, robots can detect obstacles and avoid them, so that they traverse a simple labyrinth.

How to play Volleyball with LEGO Mindstorms EV3 robots?
Here is Mintonet. The robot is created to be used in pairs, but you can also build just one and practice your shooting with a box. The robot works with plastic balls between 5 and 7 cm. Using the ultrasonic sensor it can detect either its partner or a box and then it shoots. How many balls can you score?

How to play the Telephone Game with LEGO Mindstorms EV3 robots?
In the Telephone is played with 2 or more robots and is extremelly funny. Each robot has a color wheel that can be rotated through the medium motor and a color sensor. The first robot on the left rotates the color wheel to a random color. The second robot must detect the color on the wheel and rotate its color wheel to this color. The third detects the color wheel of the second and so on.
It is described in details in Lesson 4 of Level C2. Cooperation
