Picking Up Moving Object from Conveyor Belt without using Vision Sensor
Hi Everyone, I have seen V-REP scenes in which an object moves along the conveyer belt, gets detected at a proximity sensor, belt stops, and then it is picked up by the robot. What if I want to do the same scene but without stopping the conveyer belt, how can we do it without using a vision sensor ?...

Re: How to set a rectangular workspace on a conveyer belt
http://www.onemathematicalcat.org/Math/Geometry_obj/graphics/quadrilateral.bmp Let \(\alpha,\beta\) two real numbers uniformly sampled from \([0,1]\) you can define your point as \(p=(1-\beta) ((1-\alpha) A + \alpha D) + \beta ((1-\alpha) B + \alpha C)\) In Lua code: function interp(a,b,t) local r=...

Re: How to set a rectangular workspace on a conveyer belt
Not sure I understand what you mean. You can define a quadrilateral with 4 dummies, and sample a point inside it using math.random . Hi fferi, Thanks for the reply. This is exactly what i am trying to do. Can you please elaborate a bit about how to define the quadrilateral and sample point? Thanks ...

Not outside that rectangle. How can i define that rectangle in vrep through my code? Is there any way that the ta...

Fake Grasping with ROBOTIQ_85
Hi, I attached ROBOTIQ_85 gripper to Jaco for Pick and Place using Motion Planning with OMPL. I tried the fake grasping method as it is told in the script of the gripper. The problem is that the claws of gripper ar not fully closing there is space between the object and claws. I am attaching a pictu...

Re: RG2 gripper Keeps on Falling from Jaco Arm
I guess there are many ways to implement this. How this was implemented in the scene you mention is following: First, we try to reach an approach pose. This is typically a couple of centimeters away from the goal pose. This is handled via path planning functions. That approach pose is normally spec...

Re: RG2 gripper Keeps on Falling from Jaco Arm
From the picture it looks ok. But it is just a picture. Please post the scene. To make the gripper open/close slower/faster, adjust the variable motorVelocity in the child script attached to the gripper base. Cheers Hi Coppelia, Bundle of thanks for the help, it got resolved when I made the IKTip c...
