In order to maintain the simulation speed in an acceptable rate, we should use few and simple objects. 1ODE . http://www.ode.org
For this reason, the simulated robot was modeled with simple objects, as rectangles and cylinders, and they have only the necessary articulations to perform the gait. Thus, body parts as the head and the tail are not present in the modeled robot. In order to keep our robot project simple, the joints used in the robots legs just move around the z axis of the robot (the same axis of our knees), and the simulations just used robots walking in a straight line. In the near future, we plan to extend our system to accept more complex robot models and joints.

Several robot types were developed and tested, before we de_ned the _nal main model presented here, that is
shown in Figure 1. The Table 1 shows the dimensions of the robot in centimeters. The simulated robots dimen-
