Hi all,
I'm currently working on implementing cobots in our factory. What are some the best ways to mount a robot? The cobot is going to be used for a pick and place application. We've tried mounting the robot to a beam above the work space, also placed the cobot on the wall. Both ceiling and wall have limited the robots joint mobility. We may try placing the robot in front of the table (like the operator). What methods has the community adopted for mounting a cobot? What type of mounting does the Path feature work best for? Thank you for your time.

@ArigatoMrCoboto we generally deploy our robots on a pedastal stand. It’s a 6” column of 8020 material that is secured to the floor. This allows us to have maximum joint mobility, we have robots that work high and low using these stands. We have also mounted a couple of robots directly to the table where the work is being done. This works well when the joint positions can accommodate being on a table top as you don’t worry about any misplacemrnt or movement between the robot stand and the workpiece. I’d say though that 85% of all our robots in the field are on stands that sit in front of the equipment roughly where the operator used to stand. -

At Vention we have over 40+ public Robot Stand assemblies and have mounting plates for UR3, UR5 and UR10.
Check them out for inspiration; you can always customize the design to your liking, or create your own!

PS: if you think a part is missing from our Parts Library and would be beneficial to others, we would be happy to publish it.
Thank you very much indeed for the response.

Do you bolt base of UR robot directly to table or you use dampers between robot and table?
Right now I have mounted UR on a base plate made up of aluminium, which sits on top of table and we can feel small vibration at end effector whenever it operates.
Thank you for your time.
The table needs to be rigid as in motion the robot is transferring a lot of torque through that plate and so if not rigid it will cause vibration issues. Are the vibrations you are feeling when the robot is sitting still? If so, what type of robot? I know the UR3 used to be bad about having a vibration at the end of arm but that is mostly gone with later software releases.
There is no vibration when robot is sitting still. But when it is in motion we can feel vibration at end of robot.
I am planning to bolt UR3 to an half inch aluminium plate and then use aluminium spacer between half inch plate and table.
Do think that's right way to build a rigid base ?
Thank you for your time.
If I understood your mounting correctly then its bolting Robot to 3/4" aluminum plate (as a table top) and placing it on table without any additional mounts or rubber dampers?
