From a mechanical point of view, the wristthe last three joints of robot’s mechanism (for six axis robot: J4 / J5 / J6) More mechanism is the most interesting part of the robot arm. It is always interesting for me to see how this part of the robot is built in different types of arms. Fortunately we have YouTube, so it’s possible to look under the cover without dissembling robot by yourself 🙂 Here is a short list of my favourite videos showing different solutions.
Check the best Industrial robots book
“Everything you need to know about Robotics from beginner to expert!”
“Terms like Kinematics and Forward/Inverse kinematics sound complicated while in this book they are describe in such a way that a child can understand it.”
“Highly recommended.”
Robot gearboxes, oil and greases
As you see a robot wrist mechanism could be really complex. Another interesting thing inside a robot arm are gearboxes for axes A1-A3. Today everyone uses harmonic gearboxes which are a pretty complicated mechanism. Below is a video explaining how they work.
Remember that for unbroken, fault-free robot work is necessary to think about proper lubrication. Always use oils and gears recommended by your robot provider. Read carefully maintenance manual, they could be different for each axis!

Glad you love my video! Me too.

Cheers!
All the best!
