Hello,
I created walking robot on v-rep.
I executed simulation on same status. But I got very different result per simulation.
What is cause for different result? random seed or rounding error or time step?
If cause is these, what should I do for getting result as same as possible?
Dynamics engine: ODE
Dynamics setting: Accurate
Simulation time step: 5.0 ms
Thank you.
Completely equal result per simulation
Re: Completely equal result per simulation
Hello,
when you do dynamic simulation, there are collisions to identify and constraints to solve. Many solvers randomly mix the order in which things are calculated, in order to avoid bias of various origin. But it really depends on the engine and settings. I am afraid you cannot influence that. Have you tried with the other engines?
Cheers
