This paper presents an original rehabilitative robotic walking simulation device. As a novel feature, it can duplicate the walking motion of the feet completely by including the motion of the metatarsophalangeal joints as well. It is also adjustable to different foot sizes and gait parameters such as speed, step length, and foot elevation. The presented device comprises two identical mechanisms that simulate the right and left feet. Each mechanism is designed as a planar parallel manipulator with three degrees of freedom and thus its platform (i.e. foot plate) can duplicate the sagittal-plane motion of a foot completely. A prototype of the device is already built, patented, and tested by several people, two of whom are physiotherapists. In the paper, the inverse and forward kinematic analyses of each parallel manipulator are also presented. The inverse kinematic analysis is carried out based on a typical gait cycle data of a healthy person gathered from the related literature. The results of the inverse kinematic analysis are then used as reference trajectory data in testing the device with different healthy people at different speeds.

OBJECT-ORIENTED REPRESENTATION OF A ROBOT MANIPULATOR Zontul, H; Ersak, Aydın (1994-04-14) The paper presents an object-oriented representation of a robot manipulator. The representation developed here is appropriate to implement a robot simulation package. The software package is easy to use and gives insight to the robot kinematics, the dynamics and the control subjects. The robot representation has been tested in resolved motion rate control and hybrid position/force control applications.
Towards an on-line neural conditioning model for mobile robots Şahin, Erol (2001-01-01) This paper presents a neural conditioning model for on-line learning of behaviors on mobile robots. The model is based on Grossberg's neural model of conditioning as recently implemented by Chang and Gaudiano. It attempts to tackle some of the limitations of the original model by (1) using a temporal difference of the reinforcement to drive learning, (2) adding eligibility trace mechanisms to dissociate behavior generation from learning, (3) automatically categorizing sensor readings and (4) bootstrapping t...

Design and Development of a Robotic Flapping Wing Mechanism Çakır, Hasan; Kurtuluş, Dilek Funda (2016-10-28) This paper presents the design and technical features of a robotic flapping wing mechanism and the experimental analysis of 3-D sweeping wings. The wing has three rotational degrees of freedom, which allows the adjustment of different flapping trajectories separately. Three computer-controlled brushless motors drive the three rotational axis of the wing, and the mechanism is equipped with ATI NANO 17 transducer to measure the instantaneous aerodynamic forces. A special software and graphic user interference...
Design, simulation and fabrication of a MEMS based levitated platform for laser scanner applications Kaya, Onurcan; Azgın, Kıvanç; Department of Mechanical Engineering (2017) This thesis presents design, simulation and fabrication of a MEMS based levitated platform for laser scanner applications. Electrostatic detection and actuation are utilized for levitation of the platform. There are a number of laser scanners presented in the literature for several applications. All of the scanners in the literature are based on a mechanically suspended structure, which redirects a light source. Mechanical connection of those structures limits the maximum achievable scan range. This work re...
