This paper reports the motion control of a wall climbing robot. The robot has a pair of driving wheels and a coaxial propeller thruster. Two wheels are used for running on walls, and the thruster located on a gimbal mechanism is controlled corresponding to the orientation of the robot and the slope angle of the wall. The orientation control of the gimbal mechanism is newly proposed, and is experimentally...
This paper reports experimental and simulation results of a compact wall-climbing robot. The robot has been developed with the aim to detect or repair inspections and flaws on walls. First, the mechanical structure of the robot is summarized, and the remote and autonomous control system is also described. Next, we focus on running on walls and transferring between two different walls. The experimental...
This paper presents a new compact and rapid wall-climber. First the compact structure of the robot is introduced, which has a pair of driving wheels and a tilt-variable thruster with a set of coaxial propellers. Next the whole dual-control system is constructed, which is composed of both the remote and autonomous control. Then basic experiments are shown concerned with the tilt angle control and the...
This paper presents the mechanical and control design of a caster to reduce the impulsive accelerations and residual vibrations of carts. The main theme is to remove the cart disturbances from roads by mechanical and control design. The mechanical design based on the center of percussion of the caster is proposed to reduce the impulsive accelerations caused by road bumps, and the reduction effect...
This paper proposes a new mechanism of the Braille display unit based on the inverse principle of the tuned mass damper. To realize the mechanism, the first spring named Σ-typed spring is newly designed and analyzed by using the cantilever model. Furthermore, the dynamical model of the driving unit is also derived based on classical mechanics to design the entire motion in advance. Then the experimental...
