question about vrep

Hi: I am recently running my robot in V-REP with Python, I run the simulation repeatedly by connect_simulator, start_simulation,stop_simulation,disconnect_simulator I found that the recording curves of joint positions in Graph would leap to a large value at start as show in picture https://timgsa.ba...

how to export pictures from vrep

Hi,

I want to insert robot picture of V-REP in my thesis, is there any method to get a clear picture of robots in V-REP except screen shot

Thanks a lot!

What's the difference between joint velocity and object velocity

Hi, When I record joint angular velocity v in Graph in V-REP , it only shows a set of one-dimensional data. But when I want to record joint angular velocity in remoteAPI in Python , I use simxGetObjectVelocity but return a set of three-dimensional data, vx,vy,vz So do these angular velocities has a ...

Re: how to run simulations circularly and automatically

Hi, Let's make it concretely. Suppose we have two variables , a = [0,10] and b =[1,5] , in Python Remote API, we begin simulations when a = 0, b =1, every time when simulation stop , a and b should both plus one , a = 1 and b = 2 , and then simulation start again. So how could I change the value of ...

Re: how to run simulations circularly and automatically

Hi, Though have read the rosInterface helper tool.ttl , I still have no idea how to write customization script interface with Python. And I am wondering if you've misunderstanding what I mean, I think it's better to write code in Python API to make simulation keep running circularly and change param...

Re: how to run simulations circularly and automatically

Hi,
Thank you for your quick reply!

Do we have any examples about customization scripts that I can refer to?

how to run simulations circularly and automatically

Hi, I am using V-REP with Python API to simulate the walking process of my robot, to make the robot perform perfectly, I have to adjust some parameters which could be a heavy work. So I want to run the simulation circularly and adjust these parameters automatically to find the optimums. But I have n...

how to show the trajectory of the center of mass of my robot

Hi,

Since my robot could walk and run in V-REP, I want to get the trajectory of the COM(center of mass) of my robot to have a further study of it.
Would you please tell me how to get the trajectory

Thank you in advance.

Problem in VREP Simulation with Python Api

Hello, I am using VREP to simulate our robot with Python Api. There are two versions of our robot, the first version transleg1 could walk normally when we start the simulation, but the second one transleg2 doesn't move when simulate. Here is our scene https://www.dropbox.com/s/od90g6vxk21dz75/Transl...

Re: Dynamical properties of joints for moving hexapods

Hi, spinang

I am also working on using a CPG model to control robots, but I have no idea how to implement it in C++. I am wondering if it is possible that you could share the could with me.

Thanks a lot
