In this video tutorial we experiment with different ways of solving the sports mission for throwing the ball. We show seven different LEGO MIndstorms EV3 and NXT robot constructions and attachements. Most of the techniques could be applied for any mission involving throwing a ball or an object.
Rubber bands can be quite powerful. Based on several requests from you we are starting a series on using the LEGO Rubber bands available in the Mindstorms set.
Here we continue examining FLL 2014 World Class missions. We show different ways, for putting the insert in place as well as taking the loop from the robotics arm. Some of them are quite specific, which reminds us, that you need to think out of the box, while solving the missions.
In part one we build an attachment that uses a rubber band to solve a competition challenge. The rubber band was released with the use of a motor. In this video we are removing the dependency on the motor and you could use the motor for other missions.
The robot attachment build in this tutorial gives an idea on how to release a rubber band at a specific moment using a motor. It's a simple, but yet powerful technique on using rubber bands.
Many teams are having troubles with the EV3 Gyro Sensor and its drift. In this video we are showing one way to fix this behaviour and get an accurate measurement from the sensor.
The EV3 Gyro sensor is quite powerful, but there are some little tricks when using it. In the previous episode we showed a hardware solution to the problem and now we are exploring how could the sensor be calibrated from the EV3-G software. Thanks to Sharon and Faye (full names omitted) for the request for this video.
This time we stop on "Using the Right Senses" mission, or actually on how to solve the "Right Senses" mission without "Senses" (sensors). To achieve that we use the carabineer counstructed in one of the previous tutorials, of course after a small modification.
Based on a request we are showing the robot construction with two rear motors instead of a differential. In this way, as a construction, it is closer to more students, but much more challеnging for programing.
