Skid-steered robots are commonly used in outdoor applications due to their mechanical simplicity, high maneuverability, and robustness. The maneuverability of these robots allows them, under ideal conditions (e.g., flat terrain and powerful actuators), to perform turning maneuvers ranging from point turns to straight line motion. However, sloped terrain, terrain with high friction, or actuator ...

Leg-wheel architectures for locomotion systems offer many advantages, not the least of which is reconfigurability of wheelaxle with respect to the chassis. Thus, locomotion systems with multiple leg-wheels now permit enormous reconfigurability of the chassis frame with respect to the ground frame. We seek to systematically exploit this ability to reconfigure within this highly-redundant system ...

The purpose of this study is to develop a self-balancing controller (SBC) for one-wheeled vehicles (OWVs). The composition of the OWV system includes: a DSP motion card, a wheel motor, and its driver. In addition, a tilt and a gyro, for sensing the angle and angular velocity of the body slope, are used to realize self-balancing controls. OWV, a kind of unicycle robot, can be dealt with as a mob...

Autonomous vehicles have potential applications in many fields, such as replacing humans in hazardous environments, conducting military missions, and performing routine tasks for industry. Driving ground vehicles is an area where human performance has proven to be reliable. Drivers typically respond quickly to sudden changes in their environment. While other control techniques may be used to co...

The multibody dynamics analysis software, AUTOSIM, is used to develop automated linear and nonlinear models for the hand derived motorcycle models presented in (Sharp, 1971, 1994b). A more comprehensive model, based on previous work (Sharp and Limebeer, 2001), is also derived and extended. One version of the code uses AUTOSIM to produce a FORTRAN or C program which solves the nonlinear equation...

Robotic ground vehicles are systems that use gravity and contact forces with the ground to perform motion. In this paper we will focus on n-wheeled vehicles able to perform motion with all the wheels maintaining contact at the same time. The main goal of this work is to establish the implication of the topological architecture of the vehicle mechanism on criteria such as climbing skills, robust...

Hunimua Harbor is the link between Ambon Island and Seram Island. The flow of growth in sea transportation users at Port last five years has increased. preliminary analysis shows that 2021 passenger 21%, 2-wheeled vehicle 17%, 4/6-wheeled 24%, ship visit 5%, respectively, Berth Occupancy Ratio (BOR) 72%. results showed average annual load over next ten was 1.7% for passengers, 1.2% R-2 vehicles...
