1. High degree-of-freedom systems can experience instability as errors accumulate in the numerical method. Both of these simulations seem fine--initially. But after a few seconds, the simulation on the right becomes infeasible. This would be a major problem for a simulation-based planning algorithm.

  3. This is the 3rd generation marionette experiment developed in our laboratory. We used the epuck actuators with magnetic wheels, but found that the ultimately the system was underpowered. Nevertheless, the basic idea is already present.
