How To Interface Camera And Robot Arm With Raspberry Pi
Featuring a Broadcom/ARM SoC (System on Chip) with a GPU, RAM, and both wireless and wired connectivity options (via the Ethernet port on full-size models), the Raspberry Pi is a highly versatile piece of kit.
Its small size and processing power brand it ideal for robotics. In this article, nosotros'll accept a look at ten impressive robotics projects created using a Raspberry Pi.
1. Raspberry Pi Humanoid Robot
Humanoid robots are growing in popularity and may have features such as ultrasonic distance sensing, wireless control, and obstacle avoidance. In this project, a Robotis Bioloid kit, distance sensor, and gyroscope are required.
The maker advises using a smaller Raspberry Pi Zero instead of a full-size model. To power the Raspberry Pi Zero, a unmarried-cell battery (2500mAh) must be used. Also, an analog-to-digital converter chip is required to read the sensor information.
ii. Petoi Robotic True cat
Many children and adults would love a robot pet. Rongzhong Li has developed an open-source robotic true cat project, Nybble. The team has substituted 3D-printed parts with laser-cut wooden ones. Other components include a Raspberry Pi 3B+, a Sparkfun Arduino Pro Mini, and the Nybble kit.
The mobility of Nybble is handled by an Arduino-compatible microcontroller. It retains "musculus retention" of how to move around. To aid Nybble's observation and controlling, the Raspberry Pi is installed on top of its back. Y'all tin as well modify the programming in Nybble to send simple commands like "walk" or "turn left".
3. Raspberry Pi Devastator Robot
This is the Devastator Robot! This robotic tank can exist congenital past incorporating a Raspberry Pi Aught Due west with the Devastator tank mobile platform. The build includes a motor controller circuit and some Python code, equally well equally a mounted camera with a custom bracket which can be created by using a 3D printer.
With the new Raspberry Pi Zero 2 Westward at present available, you lot may also desire to consider using that instead for more free energy efficiency.
4. Miniature Fighting Robot
It's a miniature fighting robot made with a Raspberry Pi Zilch. Inputs from a Bluetooth game controller are translated into commands for the motor controllers connected via GPIO. Rather than using a classic RC transmitter, this beginner-friendly arroyo via GPIO pins makes it ideal for younger users.
A L298N board handles the two N20 gear motors that provide locomotion, while a Tarot TL300G ESC is responsible for spinning the brushless motor attached to the "bow tie" spinner in the front. Add in a Turnigy 500mAh 3S battery pack and yous've got everything needed to fit into the robot's 3D printed chassis.
five. Pi Roomba
The Roomba is an autonomous robot vacuum cleaner. This projection shows yous how to create your ain special Pi Roomba robot with more intelligent motion!
A Roomba 530 with a series interface is required, so you can connect the Raspberry Pi, which is powered past an 18V battery.
For the coding part, it utilizes a Java packet that uses RXTX behind the scenes to communicate with the robot and a user interface that provides a "joystick" to steer the Roomba, and a set of level meters that indicate the output from the six "light crash-land sensors".
6. CHOP Quadruped Robot
CHOP is a quadruped DIY robot that works similarly to the Boston Dynamics Spot. CHOP is an open-source project, then you can modify it with off-the-shelf parts and a few 3D press components.
Its principal components are a Raspberry Pi 4B and an Arduino Mega. While the Mega connects to the servo controllers and filters data from sensors such as the inertial measurement unit of measurement, the Pi takes it all in and runs a series of Python scripts to summate the robot's gait. Information technology also controls which way the servos should motion using an changed kinematics model.
A Bluetooth remote controller delivers commands to the Raspberry Pi to regulate the direction in which the robot's body should accelerate.
7. Spot Micro
This is a miniature version of the popular Spot quadruped robot. The Spot Micro bot has a three-axis bending command/body posture control way that tin can accomplish 'trot gait' or 'walk gait' using the keyboard.
The software is operating on a Raspberry Pi 3B with Ubuntu 16.04 installed. In an ROS framework, it's fabricated of C++ and Python nodes.
The main components required are: Raspberry Pi 3B, a servo control board based on the PCA9685, servos, 16x2 I2C LCD panel, 4000mAh Lipo battery, direct connection to servo board for servo power, 5V voltage regulator to power Raspberry Pi, PCA9685 control board, custom 3D printed parts, every bit well as an optional Lidar for room mapping.
8. Ping Pong Robot
As its proper noun suggests, this robot can play ping-pong (aka table tennis). Highly intelligent, information technology can adjust its gameplay difficulty from simple to avant-garde.
Play against this ping-pong robot for some serious do or leisure. While yous could purchase a similar commercial bot for over $two,000, this 1 can be built effortlessly with existing parts, laser-cut components, and 3D printed parts. It can likewise bear about 100 TT balls, and connects via WiFi.
9. Cryptocurrency Robot
Looking for an open-source cryptocurrency trading solution? Then check out this projection, a Raspberry Pi robot that serves every bit a fully automated self-operating cryptocurrency trading projection. The projection is designed in such a mode that if sure parameters are followed, then trading of cryptocurrency will occur automatically.
In this device, the Raspberry Pi iv is held inside a custom-built case along with an LCD screen. The front panel displays processor temperature, CPU usage, and current availability of storage infinite.
On the software side of things, the Raspberry Pi Os is at the centre of it, running trading software developed by Goose Representative one with Python programming. Existence open-source means that with minimal Python coding experience, you could modify the code to utilize your trading account with lilliputian hassle.
10. Butter Robot
The Butter Robot is able to tape or stream a video with the Raspberry Pi Camera Module and a USB device. It tin can also capture and output audio.
At its core, this modest rover bot is comprised of a Raspberry Pi Zero W, Camera Module, servos, and the DC motors are connected with a L9110 motor driver. The robot operates through a Blynk app, which also supports a video stream.
The video stream was established past using MJPG streamer. Finally, a ServoBlaster was used to control servos as it retained the PWM output in the groundwork. The components required for making this robot are: Raspberry Pi Goose egg W, RPi Photographic camera Module, USB sound lath, L9110 motor driver, DC geared motors, 9g servo, 3mm LED, speaker, slide switch, and bombardment pack.
Which Raspberry Pi Robotics Project Will You Make?
In this article, we have taken a await at 10 dissimilar purpose-congenital robots that brand apply of the Raspberry Pi. Most of the robots are programmed using the easy-to-learn Python language.
These projects crave a basic to intermediate skill level. Earlier commencing any project, consider which Raspberry Pi model is best to use, also as whatever modifications yous desire to make.
