Great project, I've been wanting to do something similar with a Raspberry Pi.

What kind of tasks can the robot perform?
john_doe 6 months ago next
The robot can perform basic tasks like setting reminders, playing music, and checking the weather.

Can you share more about how you interfaced the Raspberry Pi and Arduino?
john_doe 6 months ago next
I used the RPi's GPIO pins to send control signals to the Arduino which interfaces with the motors and sensors.

Thanks for sharing! I've been trying to get my RPi and Arduino to talk to each other and that's exactly what I needed to see.

This is so cool! How long did it take you to build?
build_it 6 months ago next
I built mine over the course of a month. I had to order a lot of the parts online.

I used Fusion 360 to design mine too! It's a great tool for beginners and experts alike.

What 3D printing software did you use to design the robot?
timmy_maker 6 months ago next
Check out Fusion 360, it's free and has a ton of features.

I'm working on a similar project with a quadcopter and a Raspberry Pi. Can't wait to see what you do next!
john_doe 6 months ago next
Wow, a quadcopter with a RPi would be awesome! Keep up the good work and share a link to your project here when it's done.
bebop_builder 6 months ago next
I will definitely share it here once it's done! I'm still trying to figure out how to interface the RPi with the quadcopter's motors.

What cameras and sensors did you use with the robot?
john_doe 6 months ago next
For the cameras, I used a USB webcam for the head and a smaller camera for the torso. I also used an ultrasonic distance sensor and an accelerometer.

Thanks for the info! I'm thinking of starting a similar project and I want to make sure I have the right materials.

Have you considered using a different type of board, like the Jetson Nano or the LattePanda?
john_doe 6 months ago next
I looked into the Jetson Nano but it was a little too expensive for my budget. The Raspberry Pi was a more cost-effective option.

Nice job on the project! Have you looked into using computer vision to improve the robot's mobility?
john_doe 6 months ago next
I haven't yet, but that's a great idea! I'll look into implementing computer vision for the robot's next iteration.
