Building instructions for a LEGO Mindstorms EV3 Motorcycle, but this time with helper wheels. The helper wheels solve the problem of making turns with the robot. If the robot loses balance it will fall. The goal of the helper wheels is to make it easier for the robot to turn. Small modification, but really make a difference.

Real Steel Boxing Robot from LEGO Mindstorms
This is a LEGO Mindstorms Boxing robot. The inspiration story goes like this "One day we though - Let's play SUMO at this robotics demonstration, but let's make it more interesting. Let's play sumo with Humanoid Robots". We decided to build a boxing robot. The goal of the robot is to press the touch sensor on the other robot and it could be very fun. Perfect robot for demonstration. It is controlled by a joystick using the Bluetooth connection.
Here are the joystick and the programs for the joystick and the robots.

Susan and Mark - a LEGO Mindstorms EV3 T-Rex chasing a car
Susan comes from Sue, which is the name of the largest fully preserved specimen of T-Rexes.
Mark comes from Marc Bolan, who is the lead singer/gutarist of the band T-Rex.
The robot is made to resemble a T-Rex (Susan) chasing a car (Mark).
The T-Rex uses a Large motor to go forward and backward. The other Large motor is used for the car, which resembles a very simple 4-wheel vechicle. Susan's task is to spot Mark using the current power option of the motor rotation sensor. As T-Rexes can not notice you if you are moving very slow, Mark is trying his best to move really slow so that he doesn't get spotted!
