@t27 how to use SimMechanics for CAD model Dynamics value ?

@aak2166 Sir How you integrate your arm with Moveit ? is it based on Arduino ??

@Javier V. Gómez Sir i have solved that issue after this and create my URDF file with Solidworks .

@lr101095 This page show as "Please email Rethink Robotics to gain permission" whats there on that page may you share w

@Prof. xavier have you done Arduino tutorial for serial communication between ROS and Arduino ? if yes then you can eas

@medhijk have you Write the code for your Arduino ? In this processes Arduino is used with ROS Serial , you can check A

@gvdhoorn Sir i am saying because i have done that Work last month

@gvdhoorn it takes only .STL extension i use that so many times in my urdf files

@Prof. xavier may You post the Error, that occur while publishing angle ?

@Ibrahim i am new in ROS and now i am doing motion planing for my Robotic arm . i Generate all the Moveit configuration

@nbro Sorry if i have spam or duplicate i not check anyone's post . i have this REP when i am stuck at problem of mine

Check this REP for co-ordination system ClickHere

@Ibrahim_aerospace may you post the error ?

@Ibrahim_aerospace Change some steps there only and it work fine replace indigo with Kinetic

@Ibrahim_aerospace Change some steps there only and it work fine

yeah So post Answer and mark it Answered

@Oh233 sorry for late reply , you then select joint specific . i mean which is revolute and which is prismatic . i done

@oh233 when you design create a referance coordinate fram at base of your robot and then chose that while configure the

@Trexo may u more clarify the question with screenshot or any other form that show us error ?

@ferasb and @PeteBlackerThe3rd use solidworks , it provide you add-on for URDF . You can create your 3D model and then y

Hi all ,

I create a one URDF file from Solidworks and i tried to rotate its joint . then i get Wrong origin of joint . i mean when i rotate joint of Robotic arm its rotate about its base joint not about its axis . i need to define cooridante frame in specific direction or need to create every joint cooridante system in specific directions

here is my URDF code :-

I have solved this issue with URDF base coordinates and with its reference joint coordinates i attached screenshot here

@gvdhoorn Sir help me to be more specific about URDF wizard information , so that i learn . in SW tutorials not explain

URDF joint not Rotate about its origin Hi all , I create a one URDF file from Solidworks and i tried to rotate its joi

@delb Done Sir

URDF joint not Rotate about its origin Hi all , I create a one URDF file from Solidworks and i tried to rotate its joi

@gvdhoorn Sir i chose them Right in solidworks wizard and then after geting URDF file i manually translate links from

@delb how with ctrl+k may u tell me more??

URDF joint not Rotate about its origin Hi all , I create a one URDF file from Solidworks and i tried to rotate its joi

try to add servo library also :)

@billy Thank you Sir :)

I run your code its all right on my Arduino Uno Do Two things 1).Add servo library 2).rostopic pub servo std_msgs/Str

Robotic arm programming using Scripts Hi all , i have one three link arm that i have design in Solidworks and i want to

I have Done now Sir @RajashekharVS
