Mobile platform control with interface - hardware and software issues

Kacprzak R. Z., Bartoszewicz A.

Poznan University of Technology Academic Journals. Electrical Engineering

2007

No 56

183-196

In this chapter the idea of mobile robot control with a low-cost haptic interface is proposed and architecture of the designed and built haptic system is presented. Both hardware and software issues are described. Furthermore, the benefits of using the devices with embedded force-feedback loop are discussed.

An automated osteotomy design for autologous bone grafts in craniofacial surgery

In the treatment of craniofacial osseous defects it is frequently required that the surgeon has to graft bone to replace a missing or surgically removed segment. The reconstruction of this area poses a difficult challenge owing to the complexity of its bony structures as well as to its great importance for the chewing and speech ability. A common method of surgically reconstructing the craniofacial region involves using autologous grafts. By using the registration framework a novel surgery planning method has been developed. The method enables computer-aided selection of optimal donor sites for autologous bone grafts in the craniofacial surgery. The main advantage of the method is that after determination of the initial conditions and constraints it provides an automatic procedure to find the best fitting position. All generated solutions can be explored interactively on the computer display via an efficient graphical interface. Applying different similarity measures enables the surgeon to select the optimal donor site not only in terms of bone surface correlation but also according to the whole volumetric information contained in both data sets. This new approach permits more precise planning of the surgical procedure, reducing intraoperative time and improving the postoperative outcome.
