Contact us

Stuck on a build, spotted an error in a guide, or want us to cover a specific robotic arm project? We'd genuinely love to hear from you — reader questions shape what we write next, and corrections keep the guides accurate for everyone.

Email: hello [at] diyroboticarm.com
We read everything and reply to as much as we can, usually within a few days.

What you can write to us about

• Build help — your arm won't move, jitters, or sags, and you're stuck.
• Corrections — a wiring detail, part number, or code snippet looks off.
• Requests — a build, part, or concept you'd like a guide on.
• Sharing — you built something from a guide and want to show it off.

Before you write (so we can help faster)

If you're troubleshooting a build, the more detail you include, the faster we can pinpoint the problem. Please tell us:

• Your microcontroller (Arduino Uno, ESP32, Raspberry Pi…).
• Which servos or motors you're using, and how they're powered.
• What's happening versus what you expected.
• What you've already tried.

Many issues — jitter, random resets, weak joints — come down to power, so it's worth skimming our guide to powering a robotic arm first. For code questions, the Arduino robotic arm code guide covers the most common sketches.
