Dagu 2dof Robot arm question
May 31, 2012
I bought this dagu 2dof arm recently
I've wired everything up and it seems to work ok, however the servo that controls the gripper seems to get very hot, even when the gripper is open. I've been switching it off after a minute or so as i don't want to damage it.
Has anyone else here used one of these? Is it normal that the gripper servo gets so hot?
I found an instruction manual for the 6dof arm on the dagu support site which seems to use the same gripper
The manual seems to indicate that if the pwm pulse high time is outside of the range 660-1300 then the servo will get very hot.
On my gripper if i use a pulse high time of around 900, the gripper seems to be fully open, but the servo still gets really hot.
A pulse of around 2100 seems to almost fully close the gripper, but the servo gets even hotter.
Does this sound right ?
Any help or advice would be greatly appreciated
