#Webots hinge joint model zip file
The sample Webots project is a package of files and folders provided as a zip file pendulum-1-2.zip. The proximal link is actuated with a torque motor, and the distal links use passive pivots with only friction. If self.getTime() - last_configuration_changed > self.TIME_CHANGE_CONFIGURATION: This sample project includes a model of a underactuated robot structured as a double pendulum with two distal links.
While self.step(int(self.getBasicTimeStep())) != -1: The world file and the controller are as follows: #VRML_SIM R2019b utf8 I expected two rotation motors would move independently. These axes cross at the anchor point and need not to be perpendicular. In this paper we restrict our attention to worm-like, vertical traveling wave locomotion and present detailed kinematics and dynamics of a planar multi-link snake robot. a joint allowing only rotational motions around two intersecting axes (2 degrees of freedom). I'm writing a double joint robots and its controller for a forward kinematics example.Īn interesting thing is that the second rotational motor attached to the first rotational motor with a link starts moving to the target position only after the first one has reached the target position. The Hinge2Joint node can be used to model a hinge2 joint, i.e.
