Inverse kinematics calculation module
Good morning, I would like to have if it is possible more informations about the properties "ignore max step sizes" and "damping" of the inverse kinematics calculation module. I'm comparing two manipulators, a traditional SCARA and a redundant SCARA, in terms of time took to brin...

Joint velocity
Good morning. I am wondering if V rep has a function which retrieves, instead of the joint position values as in sim.checkIkGroup, the joint velocity values, those obtained knowing the inverse of the Jacobian and the velocity of the gripper ( Q°=J^(-1)*S° ). In my task I'm using sim.rmlPos to follow...

sim.rmlPos ?
Good morning, I'm using "sim.rmlPos" in order to follow some objects placed on a convejor belt with my Scara robot. This should be done in inverse kinematics mode. Therefore, I decided to calculate the joints positions with "sim.checkIkGroup" and pass them to "sim.rmlPos&quo...

Re: Problem with Ik configuration
Is it possible for you to post the scene of that script? Because it's a bit tough for me to understand what happens.
Thank you for you help

Re: Problem with Ik configuration
I replace here my question. Is it possible with V-rep to reach a moving object with the end-effector of a robot with the MINIMUM ACTUATION TIME (the minimum time used by a motor to make a movement with velocity and acceleration limits)? So, without knowing WHERE the object will be reached but just k...

Re: Problem with Ik configuration
Two posts before, you said "you can't simply have the target IK dummy jump into a position instantaneously: you should gradually guide and move that dummy to where you want to be with your end-effector". I understand the idea but I can't do that. Because my robot should know that it must f...

Re: Problem with Ik configuration
Thank you. But should I work in dynamics for what I'm trying to do? Because if I put all the links of my robot in 'not dynamic' the end-effector jumps immediately to the target position.

Re: Problem with Ik configuration
Thank you for your reply. For what concern the suction pad, I supposed the problem was the distance between the pad and the object and I will solve it later. But my main issue is the other one. When a piece is created, I want to follow it with my end-effector. Why? Because I want to record the time ...

Problem with Ik configuration
Hello! I post here my scene. Inside, I created a Scara robot and a producer of pure shapes to simulate random pieces that flow on a conveyor belt. My purpose is to follow these random pieces once they pass through a proximity sensor that gives me the handle of the current piece. After some time I wo...

Re: Vision sensor does not detect objects
https://www.dropbox.com/s/qg4wy8tmiaam0id/Sensor_issue.ttt?dl=0 I'm sure the sphere is renderable . I try to clarify what I mean. In the original file there are some code lines that allow to draw a sphere. The script shows which are the coordinates of this drawn sphere. If I delete these lines of c...
