A robot a 'day'. The simplest solution that works. Turning with motors Pro Preview

Here is a good problem- turning with the motors that we've built in the previous sections of the course. You noticed that turning with the robots is quite difficult because they lose balance and they fall. So we must learn the basic thing about engineering - the simplest solution is probably good enough.

How does a motorcycle turn?

It turns not with the handlebar, but by tilting it to the left and to the right. As a motorcyclist you do it with your weight. But our motorcycle robots don't have a motorcyclist . We are also limited to the type of parts that we could use to build it. We could only use parts of the LEGO Mindstorms sets. 

Helper wheels to the help

The simplest solution is most of the time good enough. It might not be the best solution, it might not be the most beautiful solution, it might not be perfect, but it is simple and it works. And this applies to engineering a lot. Many times it is not worth the trouble of spending a lot of resources on developing more than the simplest solution. It is a matter of balance. 

We've just placed some helper wheels on the robot and now it could very easily turn. 

 

Forger - Chopper Motorcycle with assisting wheels built with LEGO Mindstorms EV3

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. 

Хендълбар – Чопър мотоциклет, направен от ЛЕГО Mindstorms EV3

Вземете един мотоциклет и започнете да махате части. Ще получите чопър. Точно като този. Той е направен от ЛЕГО Mindstorms EV3. Има един голям и един среден мотор. Може да завива леко, но когато се движи напред е наистина забавно. На Ninja - Sports Motorcycle built with LEGO Mindstorms EV3 може да откриете и „по-спортна версия“.

Засега този мотоциклет няма сензори. Той служи по-скоро за упражнение в конструирането, но ако му добавите сензори и намерите начин да ги прикрепите, изпратете ни снимка.

Присъединете се към курса A robot a "day" keeps the questions awake, където ще обсъждаме мотоциклетите по-подробно, ще се спрем на това как да ги строим и какви задачи бихме могли да изпълним с тях.
