We are sure you've seen the gears in the LEGO Mindstorms EV3 sets. They are pretty easy to use. Just add an axle and you can now rotate them. Add two gears working together and you can do miracles, like a magician. And if you put them perpendicularly to each other it gets very interesting. This is our goal with the MotoCar robot in A robot a 'day'.

Gear wheels for lifting
We use the gears to construct a mechanism that could lift objects. The gear wheels are placed perpendicularly. One is the driving wheel and the other is the driven wheel. When the motor rotates, the fork at the front will move up and down.
Balance of the construction
Notice how there is an additional frame at the bottom front of the robot.
The purpose of this frame is to keep the robot from falling. What will happen if you remove this frame? How will this influence the behaviour of the robot? Well, the robot will fall. You should always construct robots that are well balanced. and do not fall in their normal...day to day... activities.

Този Урок е използван в следните курсове и занятия.
A robot a "day" keeps the questions awake. Version 1
"How to use the LEGO robots to facilitate the learning of robotics by my student at home" or simply put - "what to build now?"
After enrolling in this course we will send you a few (1-2-3) emails each month with a title "A robot a 'day'". Each email contains a robot building instructions and/or video tutorials and/or tasks that should be accomplished. After a task is accomplished we might sometimes ask for a video or picture.
This process gives a structure of the learning process where you can learn from the content. The student participates in a course, but from home and on the schedule that you decide.

MotoCar Bot. Work with gears and levers. Two magic tricks at once. Robot 5
„Как да построим виличен повдигач, като използваме само зъбни колела и лостове без рейка“… Добре, трябва да признаем, че това е труден въпрос. Дори звучи трудно. Затова нека започнем с нещо лесно. Един ЛЕГО Mindstorms EV3 робот. Той повдига обекти във въздуха. Използва две зъбни колела, които работят заедно и се движат в различни посоки, като са перпендикулярни едно на друго… Това изречение започна отново да звучи трудно… Нека опитаме отново.
Следвайте инструкциите с тези 70+ стъпки и ще получите чудесен робот, като заедно с това ще научите лесен трик за използване на зъбни колела и промяна на посоката, в която те се въртят.
