Re: How can I use joint to realize a bend movement ?

Hello Jian,

this really depends on what kind of model you have ... is it dynamically enabled? Is it controlled via IK? Or is it a static model where you can instantly adjust joints?

Re: How do i setup Motors correctly?

Hello,

my best guess is that you are not respecting design considerations 7 from this page.

Re: Multiple V-REP instances running on same computer conflict, cannot have lua scripts write to files from latter insta

Hello, there is nothing in the source code that relates to an absolute file path on Ubuntu. Practically, all write accesses from V-REP/CoppeliaSim are within the installation folder. Some folder paths can be changed in the settings file (in system/usrset.txt). We'll have to run some tests here... Ch...

Re: License Dongle is Detected, but Still in Evaluation Mode

Hello, when you nagivate to [menu bar --> Help --> Enter license key...] does it say something like: "hardware ID" or "hardware ID (dongle)"? If it is the second, then your dongle gets correctly detected. You should have received a license key associated with your dongle. YOu should enter it in that...

Re: How to use sim.getSimulationTime() and sim.getSimulationTimeStep()

Hello Jian,

this code works fine here... just after calling sim.getSimulationTime(), print the time_1 variable to see what it contains.

Re: How to interact with robot through a laserpointer ?

You will have to set-up a switch. But that will not be reliable, since counting detections might wrongly assume the person has gone in or come out (maybe turned around in mid-way).

Better would be to have a large sensor for the whole aera.

Re: Equivalent of " sim.getIkGroupHandle" for Pthon

Hello,

you will have to call a script function that returns that value for you. Have a look at this page.

Re: How to change the joint force during Position control (PID)

Hello, make sure to carefully read this page , mainly the design considerations. Basically, depending on the used physics engines, you can't use the same masses/inertias as in the real robot. There should be more balanced-out . Typically a situation like: mass10 --> joint --> mass0.1 will be almost ...
