Live Fuglum Posted February 26, 2018 Share Posted February 26, 2018 Is it necessary to have an external air supply in order to use the vacuum gripper, or is it integrated in the robot? We only have a Ø12 hose with positive pressure(out blowing air). Is that right? Link to comment Share on other sites More sharing options...
Don Spear Posted February 26, 2018 Share Posted February 26, 2018 Hi Live, You will need an external air supply. The vacuum grippers sold by Rethink Robotics include vacuum generators so standard out blowing air will work but you will need to supply the air as the robot does not have an internal compressor. In addition, the robot components use 6mm air hoses and connections. If you have a 12mm hose, you may need an adapter to connect to the 6mm components. Finally, we recommend using 60-90psi.

Live Fuglum Posted March 5, 2018 Author Share Posted March 5, 2018 Thanks Don! When I turn on the air supply, it comes a leakage sound from the computer, and a red light is seen on the grey air pressure/vaccum adapter thing(with P-port, A-port and so on). What have we done wrong? Link to comment Share on other sites More sharing options...
Don Spear Posted March 7, 2018 Share Posted March 7, 2018 Can you please provide pictures showing what you have and where the issues are present? Link to comment Share on other sites More sharing options...
Aurora Nilsen Posted March 8, 2018 Share Posted March 8, 2018 As you can see on the picture, one light is red, its also here the leakage sound comes from. Link to comment Share on other sites More sharing options...
Live Fuglum Posted March 8, 2018 Author Share Posted March 8, 2018 On the picture you can see the red light. We found out that the leakage is from the upper closest hole. I assume there should be something in this hole in order to prevent the leakage ? Link to comment Share on other sites More sharing options...
Live Fuglum Posted March 8, 2018 Author Share Posted March 8, 2018 I'm also wondering if we have connected the air supply rigth.. Where should it be plugged in? Link to comment Share on other sites More sharing options...
Don Spear Posted March 19, 2018 Share Posted March 19, 2018 Do you encounter the same issue with the other valve? The holes you reference should not be plugged as these are exhaust ports. Link to comment Share on other sites More sharing options...
Aurora Nilsen Posted March 20, 2018 Share Posted March 20, 2018 Yup, we have the same problem with both valves. It looks like the vacuume is always on, because the gripper is able to pick the object but not place it down again. Link to comment Share on other sites More sharing options...
Don Spear Posted March 22, 2018 Share Posted March 22, 2018 Hi Aurora, How are you controlling the valves? If the gripper is able to pick a part, it sounds like the vale is working but there may be an issue with how you are controlling the valve in the software. Please provide more information about the gripper you are using and how you are commanding the valve. Best, Don Link to comment Share on other sites More sharing options...
LSMM Posted October 11, 2018 Share Posted October 11, 2018 Hi Don, Aurora and Fuglum, Would it be possible to know how you are controlling the valves using the intera SDK? python? want are the class and commands you are using? Is it using the DigitalIO class? and using the set_output(self, value, timeout=2.0) method? Thanks Link to comment Share on other sites More sharing options...
