متن کاملSampling-based Planning Algorithms Applied to Bicycles
In this paper, I explore the application of various random sampling based algorithms to dynamic models of bicycles. Starting with relatively simple 3-dimensional state space models of bicycle and working up to a more realistic 7dimensional model that incorporates skidding, I examine RRT, RG-RRT, RRT*, and LQR-RRT*.
متن کاملLocalized Detection of Abandoned Luggage

The injuries sustained are compared to see if the clinical impressions that BMX are more dangerous, and produce more facial injuries, are correct. This was found not to be true as half the children involved rode BMX bicycles, and the injuries sustained were similar to those oc...
