First, building a Raspberry Pi 5 robot with mecanum wheels brings my AI assistant to life! In this guide, I show you how to build KasslClaw Mobile. It is a robot that can move, see, and talk. It is perfect for beginners.
Quick Summary
Project: Raspberry Pi 5 robot with mecanum wheels. Total cost: ~$235 CAD. Build time: 2-3 hours. Great for learning robotics and AI.
The Vision: AI That Can Move
I have run my AI assistant on a Raspberry Pi 5 for months. However, it was always in a box. What if my AI could move? What if it could see and talk?
Today, I am building KasslClaw Mobile. This robot carries my AI around my home. Therefore, it turns a chatbot into a mobile robot.
What You Need: Hardware List
Parts List
- Freenove Mecanum Wheel Kit — Robot base (~$90 CAD)
- Raspberry Pi 5 Kit — The brain (26 TOPS)
- GPIO Extension Board — Motor connections
- USB Sound Card — Voice output (~$33 CAD)
- USB Microphone — Voice input (~$17 CAD)
- 18650 Batteries — Power source
- Battery Charger — Keep power ready
You will also need basic tools. Additionally, the kit includes most parts.
Software You Need
The robot needs these programs:
- OpenClaw AI for smart responses
- Python code for motor control
- Camera streaming for video
- Telegram bot for remote control
- Face recognition with OpenCV
- Object detection with Hailo AI
Why Use Mecanum Wheels?
Normal robots turn like tanks. They must spin to change direction. But Mecanum wheels use special rollers. Therefore, your robot can move in any direction:
- ✅ Move forward and backward
- ✅ Move side to side
- ✅ Move diagonally
- ✅ Spin in place
- ✅ Slide through doorways
This helps the camera stay level. Specifically, the robot can go through tight spaces easily.
Step-by-Step Build Guide
Step 1: Build the Robot (2-3 hours)
The kit has everything you need:
- 4 motors with gears
- Aluminum frame
- Camera mount
- Motor control board
- Sensors
- All screws and wires
The build is easy. Moreover, no soldering is needed. After the build, you have a rolling robot ready for parts.
Step 2: Set Up the Software
/forward— Move forward/left— Move left/right— Move right/spin— Spin around/patrol— Auto mode/follow— Follow face
After the build, install the software. Therefore, make sure your Pi OS is updated first.
Step 3: Add AI Vision
The Pi 5 AI Hat gives the robot smart vision:
- Face Recognition: “I see Richard in the kitchen”
- Object Detection: “The garage door is open”
- Room Mapping: Learning the house
- Motion Detection: Watching for changes
Furthermore, all processing happens on the Pi. No cloud needed.
Step 4: Add Voice
Finally, add voice for talking:
- Wake word (“Hey KasslClaw”)
- Speech recognition
- Voice responses
- Telegram voice support
What Can This Robot Do?
🏠 Home Security
- Patrol your house
- Detect problems (“Lights left on”)
- Watch pets
Because it moves, it can check more than fixed cameras.
🎮 Remote Control
- Drive from anywhere via Telegram
- See live video
- Talk through the robot
- Check your home
In addition, you can use it while traveling.
🤖 AI Features
- Follow you around
- Help find lost items
- Control smart home devices
In conclusion, this makes your AI much more useful.
Cost Breakdown
| Part | Price |

5-Week Build Plan
Week 2: Add camera and streaming
Week 3: Add remote control
Week 4: Add AI features
Week 5: Add voice and smart home
Each week builds on the last. Consequently, you will have a working robot by week 3.
Tech Specs
- Speed: ~0.5 m/s
- Battery: 2-3 hours
- Range: ~30m indoor
- AI Power: 26 TOPS
- Camera: 1080p

Why Build This Robot?
Most AI assistants sit in speakers or phones. They cannot move. However, this robot gives AI a body:
- 🤖 It can explore rooms
- 👁️ It can see and report
- 🗣️ It can talk and move
- 🏠 It is a real helper
In conclusion, it is really fun to say “I built a robot!”
FAQs
Is this kit good for beginners?
Yes! The Freenove kit needs no soldering. It has clear instructions. Build time is 2-3 hours. Additionally, the code is in Python. It is great for learning.
Why are mecanum wheels special?
Mecanum wheels have rollers at 45° angles. Therefore, the robot can move sideways. It can also move diagonally. Plus, it can spin in place. This makes it perfect for AI vision.
Can I control it remotely?
Yes! The robot uses WiFi and Telegram. You can drive it from anywhere. Moreover, you get live video and two-way audio.
Do I need a Pi 5?
No. The kit works with Pi 4B, 3B+, 3B, and Zero. However, Pi 5 is best for AI vision. It has faster processing and AI support.
What can the AI do?
With Pi 5 AI Hat, the robot can recognize faces. Additionally, it can detect objects, track motion, and read QR codes. Furthermore, it runs all AI locally without cloud.
How long does the battery last?
Two 18650 batteries run the robot for 2-3 hours. Battery life depends on motor use and AI tasks. However, spare batteries can extend runtime.
