Day by day, it is one of the most important free software and hardware development companies in the world. This, thanks to its printed circuit boards, its programming language and an extensive community that shares numerous projects. In this way, it is the maximum exponent of the maker movement that represents an extension of the DIY culture (“do it yourself”).
Thanks to that, currently, turning the most crazy ideas into reality is not so difficult. Taking into account that, with Arduino, your imagination and your desire to learn are the main limit to carry out any type of project. Especially those based on robotics that encompass everything that has to do with design, construction, operation, manufacture and application of robots or virtual entities.
As a consequence, in this post, we want to let you know what are the most advanced projects you can do with Arduino in what concerns or is linked to robotics and well, with various engineering fields of interest (mechanics, electronics, electrical, and biomedical). In addition to this, we will mention some of the best Arduino kits on the market for robotics.
List of the best robotics projects to do with Arduino from scratch
In this section of the post, basically, we will indicate What are the 10 best robotics projects that you can carry out with the help of an Arduino board in an advanced way?, starting from scratch. Therefore, most of them are interesting, attractive and amazing.
So, without further ado, find out what they are:
BB8 life size
Is about a life-size BB8 robot which was built by a genius of the maker world with a variety of recycled materials that you can find from home. In this case, it is an educational robotics project with Arduino based on the Sphero BB8 edition that it is a robot with a warrior aspect which can be used as a remote control toy or even further programming.
Thus, to build it, you simply have to resort to materials such as roll-on deodorants to function as ball bearings, in addition to, Christmas balls to make up the robot’s eyes, canvas that resembles fiberglass, etc. Added to this, with the help of an Arduino board and bluetooth connectivity, users will be able to control this robot through your own mobile device. As you will see, it is a great robotics project that does not require the use of many technological materials apparently.
A robot that maintains only the balance
Make reference to a little robot self balanced that measures 4 pulses wide and 4 inches tall; which has the ability to avoid obstacles when moving thanks to an ultrasound sensor that helps you stay balanced at all times. To build it, the base on which the robot will be created is an Arduino Pro Mini board with an MPU6050 accelerometer or gyroscope.
Other than that, a 2 to 5V boost converter is required, a DRV8833 motor driver, a US-020 ultrasonic distance sensora pair of 42x19mm wheels, a pair of micro metal gearmotors, a NCR18650 battery and bracket, 3 double-sided prototype PCBs, 4 nylon nuts, nylon spacers at 8 to 25 cm, cables, on/off switch and berg connectors.
It should be noted that, in order to create it correctly, it is appropriate to measure the angle of inclination with an accelerometer and with a gyroscope to combine the acquired results with a complementary filter. In such a way, the robot will manage to maintain balance based on the angular acceleration provided by the accelerometer and the angular velocity provided by the gyroscope.
Robotic arm
Basically, it consists of a robotic arm that displays the ability to take any target with tweezers and, in doing so, it guarantees that it will not hit any obstacle due to the ultrasonic sensor it contains. To create it, it is necessary to have a plate on hand a 6 DOF robotic arm, a generic HR-SR04 ultrasonic sensor, a 1Kohm resistor, a DC 15A power supply, an MG998 or MG995 servo and a button.
In this sense, the ultrasonic sensor is one of the most essential elements, which works by emitting a wave (Trigger) and receiving its echo (Echo). Thus, the wave travels at the speed of sound and the distance from the obstacle will have to be calculated computing the time difference between the trigger and the echo to multiply it by the speed of sound.
Considering that, by default, the ultrasonic FSM has three states that are:
- state 1: Execute the trigger.
- state 2: Check if the echo was received.
- state 3: In case the echo has been received, the FSM changes to the third state automatically and it calculates the distance. Otherwise, the FSM will return to the initial state.
GorillaBot
This is a quadruped racing robot powered by Arduino which consists of an autonomous 10-meter sprint and its design is based on a five-bar linkage mechanism for each leg and 8 servos on them in total (two power servos on each leg). Which is controlled by means of an Arduino Nano. For his part, while in standalone modethe robot maintains its heading or orientation from a magnetometer (or digital compass).
But, in case it gets lost, it will be able to avoid blocking by the help of an ultrasonic sensor that has a built-in. Also, if for some reason it goes bad, it will start to hit the wall at a 90 degree angle and it will only be necessary make use of a step counter in the code to tell you how many steps you have to take in 10 meters to get back to where you are. On the other hand, it is worth noting that, the economic construction it is 3d printable and thanks to that, the GorillaBot shows itself to be a great competitor.
An exoskeleton for stressful situations
with a plate people can undertake this project that It consists of an ideal exoskeleton to calm people in any situation of stress or anxiety. Thus, it is a wearable that values the health of the user and, therefore, its objective is based on acting as an exoskeleton that shows the ability to relax it. by emitting vibrations at the pressure points on your body.
To achieve this, the exoskeleton keeps the vibration motor on and meanwhile, the photoplethysmal pulse sensor receives a high range of hard accelerated pulses during a specific time. Once the user has calmed down (when the frequency of the pulsations is reduced), vibrations will stop automatically.
Now, in addition to an Arduino Uno, the creators or designers they need other elements to build their own exoskeleton and are: vibration motor (analog output), photophysical pulse sensor (analog input), cardboard hand model, wrist strap, electronic cable, needles, scissors, soldering iron, fabric, black dye and black thread.
Aster, a humanoid robot
This is a project that is based on a robot created and designed to simulate the shape and/or movements of a human beingso you can walk. Basically, the construction of this open source theft via Arduino is a mix between the Poppy humanoid robot project with MG996R servo motors instead of dynamixel motors.
Which guarantees a great saving of money, since the entire robot it only costs approximately 200 euros and not thousands of euros. For its part, it refers to a robotics project that is controlled from an Arduino Uno board along with a servo shield dedicated to the 16 servos and for the shape of its face, it uses a Samsung S4.
In addition, it requires 3D printing for each piece, according to the measurements that the author wants to use; the following are recommended:
- Filling: 40%.
- layer height: 0.3mm.
- Walls: 4.
- Speed: Between 40 and 60 mm/s.
parking assistant
It refers to an ideal assistant to park or park your car correctly, without fear of colliding with a wall, a column, any other objective or even a vehicle. Since it has the ability to calculate the distance to prevent this from happening and shows them using green, blue, yellow and red LED lights. Which basically reveal if you can keep driving the car, if you have to slow down, if you have to stop or if you need to back up.
To build it, it is important to make use of an Arduino Nano with an HC-SR04 ultrasonic sensor. Additionally, a 100 Ohm resistor, a buzzer, a male and female housing, a pin header connector with leads, adapters, and a color-coded ribbon cable are also required. Thanks to that, the total price of the project does not exceed 25 euros.
An Arduino snake robot
As its name indicates, it is a robotics project that looks like a snake and it is able to move autonomously because it is built from different types of servos and supports. East, works with the Arduino Mega microcontroller and in total, it contains 12 servos that facilitate their movement and control. Assessing that, can be managed through a mobile app on Android via a Bluetooth connection.
Now, to obtain it, the manufacturer provides three different kits that users can select freely, according to their skills and their availability of time. For example, the self-build kit has a price of €515, while the ready-to-use kit it costs €582 and the self-study kit It is the most expensive of all, for a price of €676.
A robot that paints the streets
Under the name of “Strettexter”, this writing robot that paints texts on the streets was created in order to raise awareness about climate change as a global movement. Basically, it consists of a robotic machine that fills with a total of 8 spray cans introduced in a wooden box and fixed on a skateboard to walk down the street. So that, it has to be activated by pulling the skateboard after being configured and connected to the electrical network.
For the robot to work correctly, it is appropriate to use a PWN/Servo display soldered to an Arduino Uno board that will have to be connected to 8 servomotors to manage to control each one of the cans of paint in a pulverized way. In addition, the project includes a table that converts each character to 5×8 bit fonts to match the size of the spray module. Added to that, has an encoder to measure the distance traveled and with a safety switch.
The mini quadruped robot Baby Cheetah
It is a smaller version of the MIT mini Cheetah that has a dimension of 23 cm x 9 cm x 9 cm. Said robot is powered by an Arduino Nano and is equipped with a total of eight SG90 servos that manage to operate each leg linkage assembly. pre-printed in 3D. To run it, you need to control a custom app thanks to a Bluetooth module HC-05 that manages to connect the mini robot to a smartphone.
Now, to build your own Baby Cheetah, You will have to count on…
