Wow thanks for the quick reply!
We are looking for this solution to pick and place seeds, which tend to be tiny but light, so I'm trying to figure out if the Dobot would be suitable, or if we need to go for an arm that is higher-end/more costly that might have more precision built in. The other option on the Dobot instead of a gripper is obviously using a smaller suction cup, or customized suction needle I guess - but I've struggled to find examples online of people customizing the suction fitting on the Dobot.
We're really at the beginning of this project so I'm a little clueless right now. If you had any further thoughts I'd love to hear!
