You need to pull. And also catch. You need a carabiner. We have done a number of videos on carabiners and this is one of the ideas for the FIRST LEGO League 2015 Trash Trek competition.
This one is very special- an attachment that could lock itself on purpose while working.
The attachment builds on previous episodes this time using two LEGO rubber bands. When a lever is released the rubber band exerts pressure on it and moves it in a circular motion. As an example we are solving the 2012 FIRST LEGO League, Senior Solutions, stove mission (which was quite interesting as a mission)
A spin turn is a turn around the center of the robot. Let's learn how to program it.
"Bot. Spy Bot."
Many of us are fascinated by the idea of spies. Movies for "spies" are also very popular and if you haven't watched them check out the 007 movies. These here are building instructions for a LEGO Mindstorms robot with two touch sensors and one ultrasonic. It could be used as a spy - sneaking closer to you and detecting if you move or if you touch it. The whole idea for this robot came from NXT when there were sound sensors. Currently, there are no sound sensors in the EV3 set, but the robot could again be quite fun to program.
Building instructions for a simple car using an EV3 Large motor for turning the front wheels and EV3 medium motor with differential for driving the rear wheels.
Mission
The robot should pass through the speed bump either from east to west or from west to east.
The robot has completely passed at least once through the speed bump during the match: 20 points.
With this program we accomplish the innovation project. Move forward and than back.
Program used for the drop attachment. Move the robot, interact with the mission model and release the wheel from the drop attachment.
