We will get to know each one of them in this guide.
The Arduino UNO board is the best to start in electronics and programming. It is super robust and is the most documented of the Arduino family.
She is the true brain of MARK, where the microcontroller resides and performs all the operations so that it works well and can be programmed.
It has all the basics to start:
A Shield is an electronic board, which expands the capabilities of another through various components, in particular the “MARK Shield” gives access to:
Each sensor has its own 3D printed enclorure and can be connected using the MARK building modules.
The kit includes 3 types of sensors external to the brain:
This sensor uses an ultrasound emitter and a receiver to measure the distance between the sensor and an object.
Sensor: Infrared TCRT5000
They are infrared sensors that work by emitting a light and a receiver can detect and measure the intensity of its reflexion.
They are switches that are activated or deactivated if they are in contact with an object.
Each actuator has its 3D printed enclosure and can be connected using the MARK building modules.
The kit includes 3 types of actuators:
Actuator: 12V 90 RPM (Ratio 298:1)
DC motors convert electrical energy into mechanical, through a magnetic field. They are one of the most used components in robotics and will help you give movement to your creations by controlling the speed at which they work.
Actuator: SG90 180° (5 V)
They are special motors, since you can move them very precisely and maintain their position.
A light-emitting diode that you can configure for various uses.
We use standard connectors, which are used in telephones and several other kits for their ease of use and reliability.
6-wire cables with easy-to-connect RJ25 connectors:
They are designed to be 3D printed and are based on a pattern that is repeated or incorporated into the different components.
The patterns have 15 free and 1 fixed positions that allow you, along with the screws and nuts, to fix the different pieces at angles of 22.5 °, so that it is easier for you to position sensors, actuators or whatever you want.
In any case, it is possible to make it compatible with other building systems by designing adapter pieces or use other materials such as cardboard or even metal, making holes of at least 5 mm.
Makeblock – In the case of using componets from the Chinese manufacturer, M4 screws and nuts should be used instead of M5.
We use M5 screws and nuts, which are widely used and is a standard measurement.
With them you can join the building modules with other parts of the kit.
The sensors and actuators as well as the brain have nuts inside their enclosures ready to use.
They are based on our pattern that you can use to create different versions or design your own pieces, using the possibilities of 3D printing.
Adjustable height of the omni wheel (47 – 97 mm)
Our recommendation is to start using a block software, which will help you to know the code little by little and will allow you to create robots with ease. For this we use mBlock, an Open Source software that you can use with MARK..
