How to Home my Dobot?

If you have used a Dobot robotic arm, it is likely that you have “homed” your Dobot before. Here’s a quick reminder of how it works:

DobotStudio just crashed for no reason and I can’t get it to work!

What happened?

Dobot Discovery: removing attachments safely

One of the advantages of Dobot over other robotic arms is the diverse array of attachments that come included in the system. This robot can manipulate objects with a gripper or suction cup,  draw beautiful designs with robotic precision, 3D print, and even laser engrave! Best of all, switching between the functionalities is as simple as replacing the end attachment.

But don’t forget! The Dobot Magician has an internal computer, and just like your laptop, it doesn’t respond well when you suddenly unplug devices.

Dobot - The suction cup bug scenarios

As we work with our new products, it’s not uncommon for us to find small bugs and issues that we don’t see documented elsewhere on the internet. When that happens, we work hard to find a solution or workaround, and post it to this blog! 

The Dobot uses a suction cup attached to an air pump to create a vacuum seal on objects you want to grab, and releases that seal when it’s time to drop the object.

Dobot suction cup is blowing air out!

This is the strangest and most elusive problem we have encountered. I suspect it occurs when the Dobot attachment has recently been switched from the gripper to the suction cup. The gripper uses the air pump to both open and close, using both positive and negative air pressure. The suction cup only uses negative air pressure (or none at all).

Dobot suction cup doesn't seem to be doing anything at all

You may have received a suction cup with a missing/undersized/partly blocked inner hole. Don’t worry, this is an easy fix.

Dobot suction cup isn't sucking hard enough to create vacuum

When using the suction cup od Dobot, you may hear the air pump humming, but the suction cup isn't sucking hard enough to create a vacuum.

DoBot Suction cap doesn't hold anything

If you experience a low suction / low pick up rate, you would like to look inside the suction cup and make sure there's no obstruction to the air flow. Sometimes the rubber isn't cut all the way through, you would like to peel it off / remove it, to allow the pump to create the vaccum.
