In the course, we are going to use the following components and hardware elements. It is important to know their names and what are they used for.
We have two power sources (batteries) - one power source is for the controller, the Raspberry PI, and one power source is for the motors. What is the separation between the power sources and why it exists? Why do we need two power sources? We need the different power sources because there is not enough power otherwise.
The course is designed to be used with almost every remote controlled car. The process of opening the car will be different for different cars but there are basic principles that you could follow.
It's fast. It's on two wheels. It's a motorcycle. And this one is built from LEGO Mindstorms EV3 sets with the use of one additional Medium Motor. If you have two medium motors, great. If you don't have you can build the Handlebar - Chopper Motorcycle built with LEGO Mindstorms EV3, because it uses one large and one medium motor that are available in any EV3 set.
Currently, the motorcycle has no sensors. It's more of an exercise in construction, but if you attach sensors and think of a way to attach them send us a picture.
Join the course A robot a "day" keeps the questions awake where we will further discuss the motors, how to build them and what tasks to accomplish with them.
You can also download the program from here.
We've just plugged in the power bank in the Raspberry Pi controller. Has it started? Is it doing something? Why is it not moving? Simply put the raspberry power a small red diode and it just emits light. Well, it's on, but it will do nothing else.
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.
Take a motorcycle and start removing parts. You get a chopper. Like this one. It is built with LEGO Mindstorms EV3. It has one large and one medium motor. It could kind of turn, but moving forward with it is very funny. There is a "more sports like version" available at Ninja - Sports Motorcycle built with LEGO Mindstorms EV3
Currently, the motorcycle has no sensors. It's more of an exercise in construction, but if you attach sensors and think of a way to attach them send us a picture.
Join the course A robot a "day" keeps the questions awake where we will further discuss the motorcycles, how to build them and what tasks to accomplish with them.
"You need to step on three points to be stable". This is something you could directly see after building this marvellous, 270+ steps, extremely interesting Motorcycle with a side cart. Yes, we are proud of it. The robot is suitable for using it at home. The instructions for building it contain more than 270+ steps so it is a test for endurance, concentration, passion. The same way driving a motorcycle is.
Or you could just step into the cart, drive along and enjoy the view while someone else is building the robot. Like a sibling or a parent.

Building instructions for probably the simplest LEGO Mindstorms EV3 Motorcycle that you could think of. Can you think of a simpler? Build it and send it to us.
The motorcycle has one large and one medium motor. Turns are hard, but we will think of solutions for turns. There are also other motorcycles, more complex ones that you could build
This is a simple robot, variation of the Earl bot using treads. You can use the attachment to kick balls sideways. The robot is useful in STEM classes where students have to construct robots quickly.
Don't we all love animals? But it is sometimes difficult to have a puppy at home. Presenting to you - the Puppy robot (drums in the back). It has some of the benefits of a Puppy - it is small, it can follow you with the Ultrasonic Sensor and it can bark (if you program it to). Follow the building instructions. Use it at home or at class.
Build from LEGO EV3 Core and Expansion set this robot looks like a scorpion. The Scorpion strikes, when it sees a pray with the ultrasonic sensor and you can use the touch sensor and the rotation sensor to control the spike movement. It has a scissor mechanism at the back using a system of gears and levers.
Instructions for building remote control. It uses the rotation sensor to determine the steering and touch sensor for handling the movement. Find building instructions for a suitable chassis here.
Together the controller and the car look like this:
Building instructions for the most simple grabber using just one Large EV3 LEGO motor. It has one static lever and one active lever.
This is version 2 of the LEGO Mindstorms Grabber. It makes use of 4 gears to make both levers active.
This is the third version of the LEGO Mindstorms Grabber. This time we use a LEGO EV3 Medium motor and worm gear to make the two levers move smoothly and symmetrically.
Instructions for building a LEGO truck. We use a medium motor for steering and a large motor for driving one of the rear wheels.
We love bears. These are great creatures. Do you know that the Polar Bear is the largest bear there is.
This robot was first constructed years ago for some of the first classes in LEGO Mindstorms Robotics that we held. It is quite challenging, but nevertheless very rewarding when completed and when you manage to program it to walk. Check it out.
We would start connecting a lot of things to the Raspberry Pi. It will be good if we could have some way of referring to the pins on the Raspberry Pi. For example like Pin 5 or Pin 26. Luckily there is such a way.
Winter might be far away or it might just be coming - depending of course on where you are in the world. But you can always spend a few hours having fun with a LEGO Mindstorms Snowmobile. A really challenging construction that requires good preparation, concentration and a lot of efforts to complete. Same is going to the mountain in the winter. But the reward at the end is worth it.
