How to build a Raspberry Pi Robot? Kits and Projects to get started

By Shawn 5 years ago

Want to know how to build a Raspberry Pi robot? This guide shows you the kits, and projects to help you easily get started in building one!

Before we introduce what you’ll need to build one, you may be wondering why to use Pi to build your next robotics project instead of the popular Arduino board. Well, both options are great, but with the Pi, you’re getting a complete computer for less than $60, alongside its seemingly small form factor, affordability, and large community support. Making it an easy way to get started even for beginners!

But if you would like to know how you can build an Arduino Robot, do check out my post on it!

What will be covered:

  • What do you need to build a Raspberry Pi Robot?
  • Raspberry Pi Robot Kits
  • Raspberry Pi Robot Projects

What do you need to build a Raspberry Pi Robot?

The first step to building anything is what are the components needed? Building a Raspberry Pi Robot is no exception, where the exhaustiveness of parts needed depends on the type of robot you’re building, alongside your budget!

Ref: instructables

Here, with have the list of components you’ll typically need to build a basic, and simple Raspberry Pi Robot:

  • Raspberry Pi board
  • Motor driver, E.g. L298 – The intermediate device between your microcontroller, batteries, and motors. Ensures all components work as it is
  • DC Motors – Provide the drive for wheels to rotate and allow for movement
  • Ultrasonic Distance Sensor – For robot detection of nearing objects
  • Voltage Regulator Circuit
  • Chassis to house modules
  • Connectivity Modules – Raspberry Pi WiFi or Bluetooth modules for control
  • Batteries

As mentioned, the above list is the minimal components required to build a simple Raspberry Pi Robot. However, you can expand your creativity by incorporating a plethora of other parts out there applicable for Raspberry Pi robot building!

To help ease the process of sourcing and buying all the parts individually, we’ve prepared Raspberry Pi robot kits that include all essential components/modules you’ll need to easily get started!

Without further ado, here’s the list of kits available at Seeed!

Raspberry Pi Robot Kits

AlphaBot, GoPigo Alternative Raspberry Pi Robot Building Kit with Pi included

Assembled Robot From the AlphaBot Kit

Totally new to Raspberry Pi and robot building? Well, this AlphaBot kit is a great way to get started as it comes with a Raspberry Pi 3 Model B alongside a wide range of modules that require no soldering and wiring. Truly a whole lot of convenience in one package!

Adding on, combining the Alphabot platform and the rich Raspberry Pi open-source resources, you can easily find module extensions or change up the design, building your very own version of a Raspberry Pi Robot!

If you would like to stick with the kit, it’s still capable of achieving what you would want a robot to do; including line tracking, obstacle avoidance, speed measuring, IR control!

Alphabot features the following:

  • Support for both Raspberry Pi/Arduino Interfaces
  • Modular design with support for plug-and-play modules
  • LM298P motor driver with a diode protection circuit for added safety
  • LM2596 voltage regulator, providing stable 5V power
  • TLC1543 AD acquisition chip for analog sensor compatibility
  • Arduino extend header

AlphaBot2, upgraded 2nd iteration of the original

Assembled Alphabot 2

Like what you’ve seen with the earlier Alphabot kit recommendation and though that was it? Well, this upgraded version brings building a Raspberry Pi Robot to the next level!

This kit shares the same robot functionality capabilities as the previous iteration (line tracking, obstacle avoiding, no soldering, wiring, etc.) but brings upgrades with its 2-layer structure that provides better stability and compatibility with multiple Raspberry Pi boards.

It’s Two-Layer Structure Includes:

Lower-layer base chassis:

  • TB6612FNG dual H-bridge motor driver rather than the L298P that provide higher efficiency, less heating in a more compact package
  • 5-ch infrared sensor, analog output, combined with PID algorithm for stable line tracking
  • N20 micro gear motors that provide lower noise at a high accuracy
  • Onboard RGB LEDs for all your aesthetic junkies out there!

Upper adapter board base (what’s new):

  • PCA9685 servo controller, make it more smoothly to rotate the pan head
  • CP2102 UART converter, easy for controlling the Pi via UART

Raspberry Pi Robot Car Kit – RC Smart Car Chassis Kit

Assembled Robot Car

Have most of the components ready and only need a chassis kit to complete your Raspberry Pi Robot Car? With this RC Smart Car Chassis Kit, you’ll be able to do just that but better!

Unlike a traditional 4-wheel robot car chassis, this car is designed similarly to a professional remote-controlled racing car; using rear-wheel drive plus front-wheel steering to achieve forward, reverse, and left-to-right turn. Directional control of the trolley is also achieved by using two steering rods through the steering gear.

The flexibility in changing motors if you’re looking to pursue high speed is made possible as well. So long as the motor is a 25mm shaft diameter one, you’re good to go!

6WD Raspberry Pi Robot Car Kit: Robot Car Kit-6WD Off-Road Chassis Kit

Assembled Robot Car

Wonder what’s better than a 4-wheeled robot car? A 6-wheeled one! This newly shock absorption design of this 6WD off-road chassis car kit allows for better road penetration capability, making it suitable for easy usage in very much every surfaces!

The 6WD mobile platform can be easily installed with your Raspberry Pi alongside sufficient mounting holes that allow for a variety of other sensors or features to be paired with your robot!

Raspberry Pi Robot Arm Kit – Waveshare 4-DOF Metal Robot Arm Kit with Bluetooth and WiFi

Assembled Raspberry Pi Robot Arm

We’ve talked about robot car and vehicle kits, but what about the Raspberry Pi Robot Arm kit? Well, here at Seeed, we got just the thing for you!

This Waveshare 4-DOF Metal Robot Arm Kit is the perfect way to get started in building a robot arm for your Raspberry Pi through its inclusion of Bluetooth/Wi-Fi capabilities, allowing you to easily control it via your smartphone!

  • If you’ve never worked with Bluetooth/WiFi, development resources and manual (examples in python like Bluetooth/Wi-Fi remote control) are included!

This Raspberry Pi Robot Arm Kit features a servo driver HAT and metal mechanical arm structure, as follow:

Servo Driver HAT Features:

  • Compatibility with Raspberry Pi Zero/Zero W/Zero WH/2B/3B/3B+
  • I2C controlled, only 2 pins used
  • Up to 16-Channel servo/PWM outputs, 12-bit resolution for each (4096 scales)

Raspberry Pi Robot Projects

Want to explore deeper into the endless creativity that lies with building a Raspberry Pi robot project? This section of today’s blog is one not miss!

I’ll be showcasing 5 of the most interesting Raspberry Pi robot projects out there in the community! Feel free to gather inspiration from these project ideas!

1. Raspberry Pi Humanoid Robot

One of the most common looking robots out there, when asked to describe a robot, is those human-looking robots. These types of robots are also known as Humanoid robots, built and made to look like humans.

Humanoid robots are used in many applications such as a marketing tool for companies, R&D, and even tasks that are unsafe for real humans to execute. Hence, it’s all-around a good option to start building one!
