I publish videos mainly related to the construction of DIY robots using 3D printing, as well as videos related to my research in the field of planning and control of multi-robotic systems and robot swarms. I also have some funny non-robot related videos here.
I focus on developing desktop robotic arms and actuators using 3D printing and off-the-shelf components.
Comments and suggestions welcome - you can use comments on videos.
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?
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?

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.
1:22 the robot must have some *insane* balance, most Bipedal robots have at least 3 DOF in their legs due to balance issues , the only other biped like that that i've seen was Gyrubot
So cool. I'm trying to make one as well. My question is why did you put that motor in the back? Counterweight? and why did you use stepper motors? are they not less efficient and weigh more? and what stepper motors did you use? and how many Nm did you need for the bottom 2 motors? and how much does the robot weight form the first motor up? and what rpm does the motors go? what gearbox did you use? Thank You so much.
You probably mean DC motors with encoders. Yes, we can use them. However, an easier way to change the speed is to change the speed setting in the firmware.
@@martinTintin476 One fast robot arm is Amber B1. It uses fast DC motors and harmonic drives. But maybe is to small to handle cnc. Industrial robots are an option too.
Thanks! The arm can be operated remotely. More precisely it can operated from computer and computer can communicate via internet. I always had remote operation in mind when developing the arm.
Amazed there's so few views for your videos so far. Following this project and looking forward to attempting a build when it's all ready. Thanks for all of your hard work :) Found you through an article on medium.
I have the same feeling about the videos. More videos are on the way. It just takes time. BTW: I started to post files in my github repository here: github.com/surynek/RR1
I have not yet published the files and the assembly documentation, but at least I put STLs for the shoulder planetary gearbox (the main lower joint) in my github: github.com/surynek/RR1. To build the gearbox you also need: 7 ball bearings - 16mm outer diameter, 5mm inner diameter, 6mm height, 3 bolts - approx. 48mm length, 5mm diameter, 1 bolt - approx 25mm, 5mm diameter, plus some 3mm screws. The bearings and bolts hold the planets and the sun in place. The exploded view of the gearbox can be seen here: surynek.net/_main/index.php?select=research#RR1 (bearings and bolts not shown). And not to forgot many 6mm bearing balls into the outer ring.
