One of the very good things about box robots is that you could easily align with them both to the front, to the back or to the rear sides. This aligning is helpful for FIRST LEGO League, World Robotics Olympiad or other robotics competitions with LEGO Mindstorms EV3/NXT robots.
This robot has a color sensor and this sensor is used for following lines. Additional Mindstorms EV3 sensors could be place on the robot, like a Gyro sensor or a second Color sensor.
Where should you lift the robot? Especially if you don`t have the mission model that we are using
Don't limit yourself to the box and think of different ways to lift the robot.
Build a robot base to use in the course. You can use the robot base provided by us or you can build one yourself.
What is the end result? - have the attached on the mission model. What is the mechanism the would make the robot hang on the mission model.
Time to lift the robot. The first approach is by using the 40 teeth gear wheels that come with the LEGO Mindstorms EV3 and NXT robotics sets.
Build a similar mechanism to this one. Similar, but for your robot. This is the task for you. Try, give yourself half and hour or even an hour.
How to align the wheels and how much should you push for this solution?
The next step of lifting a robot to a mission model is to try to use a rack.
Build a rack and try to lift the robot with this rack.
The final way for lifting our box robot is by using a scissors mechanism. In this Episode, we would discuss the benefits and advantages of this mechanism.
In this tutorial, we would drive the scissors mechanism and there are a number of rules that we must follow
Construct two legs for both sides of the robot. The task for this video is to attach this two legs on both sides and to build a system of gears and axles that power those legs.
Let us do a quick recap of the whole lifting mission and its solution
