This video introduces the second revision of the RR1 (Real Robot One) 3D-printed desktop robotic arm, that is RR1 rev. 2 in short. RR1 is a small 3D-printed robotic arm featuring 6 degrees of freedom plus one degree of freedom for gripper altogether mimicking standard industrial robots but packed in small size. The robot features closed loop control with rotary encoders attached to each joint. RR1 is powered by 7 stepper motors (6 for axes and 1 for the gripper) that transfer torque to joints via 3D-printed split-ring planetary gearbox reducers. The revision 2 has many improvements against the revision 1 (the black robot) such as PCCF gears and encoders outside joints.

That is really impressive. A really nice project. I wish you lots of fun and good father-son time.

Skvělá práce! Těším se na další updaty robota.

@pavel.surynek Месяц назад

Už pracujeme na rev.3.

cool project sir

@pavel.surynek Месяц назад

Thanks.

Great projects! i love it! and it looks like has a backlash on 3-joint or 3-joint power not enough

Good point. There is some bearing problem in the top elbow joint. I plan to exchange it.

Really impressive 🤩. Is ROS( Robot Operating System) used for controlling the arm?

@pavel.surynek Месяц назад

Thanks! My student made ROS control for the robot, code here (all rr1_... repositories): github.com/EnviloN?tab=repositories. But not yet connected to physical robot.

I am a final-year Mechatronics student, and I would like to work on a project similar to this for my graduation project. Can you please help me with resources or guide me on what to do to reach this level of proficiency?

@pavel.surynek Месяц назад

Thank you for your comment. I would not say this is a big proficiency. I recommend lot of patience and not giving up. Concerning resources you can take my CAD files from my github. There are many other projects you can take inspiration from.

@pavel.surynek, I appreciate your reply. Are there any courses you would advise me to take in robotics or mechanical engineering? I may have a little problem with programming, as I have learned only the basics in ROS, such as nodes, publishers, subscribers, services, and working with micro-ROS on Arduino. I have also worked on AVR and ARM microcontroller programming with embedded systems. This is approximately my knowledge in programming. What can I study to understand everything about this project and ensure that I can execute it successfully?
