Double-wishbone: The kinematic design of double-wishbone suspension
systems requires fulfilling with several design parameters. In this
example, we propose an initial guess linkage, and the synthesis
procedure finds the dimensions for the required tread width and camber
and toe angles. (DWSynthesis.wmv)

condition

Laparoscopic surgery tools design
Laparoscopic surgery is now widely established as a minimally invasive surgical
technique which has several benefits. Some of these benefits for patients are
pain reduction and shorter hospital stays. The main goal is to introduce
kinematic improvements in the surgical tools. Two main problems currently remain
unsolved in this sort of instrumentation: increase the number of degrees of
freedom in the kinematic motion and improve the tactile sensations of the
instruments.
In the
former case, to access the patient’s organ an improvement in the dexterity will
be desirable. In the second case, we will search for the mechanisms to obtain
the necessary feedback information. In this way, the surgeon has valuable
information about the pressure exerted and the organ stiffness
