For a research project at university I have been tasked with simulating a "robot arm". The simulation is to be compared with the real life version for accuracy. The arm will be lifting other objects and building simple structures in the demonstration.
My supervisor has asked that we build this simulator from scratch so I am currently selecting a physics engine.
In this link, it seems bullet is not accurate enough, albeit this was in 2010, for the original poster's needs in robotic simulation.
This comparison believes bullet is better in general but says that documentation is lacking, which is important to me as this is my first time using a physics engine such as this.
so thoughts on these or any other physics engine that may be more suitable?
