This paper documents the mechanical system of the Electric Cable Differential leg, and its incorporation into a monopod hopping robot named Thumper and a bipedal robot named MABEL. The ECD Leg is designed with physical springs and other passive dynamics to match a mathematically simple, bio-inspired mass-spring model, which can exhibit robust and economic walking and running gaits. With this de...

This paper presents a new 6 degree-of-freedom cable-driven parallel robot fully constrained by 8 cables. should perform medium size 3D part printing. Its distinguishing feature is radial cable winding that relevant due to the small diameter (0.54 mm) and maximum length (1.732 m, 1 m cube diagonal). solution has advantage of being compact easy design. The trajectory planning uses full geometric ...

I n this paper, we present a robot system for inpipe inspection of underground urban gas pipelines. The robot is configured as an articulated structure like a snake with a tether cable. Two active driving vehicles are located in front and rear of the system, and passive modules such as a control module are chained between the active vehicles. The proposed robot has outstanding mobility oflered ...

Although industrial robotic arms are equipped with external cables to supply electricity, gases or other materials, cable path design is a difficult and demanding task. Herein, an efficient optimization method proposed for automating under the assumption that robot motion known. The contribution of this study was reduce considerable computation time required optimization, which concern in our p...

In this study, a new cable-driven rehabilitation robot is designed, the overall design of given, and kinematic equation lower limbs in supine state human body addressed. Considering that cable winders move along rail brackets, closed vector method applied to establish model robot, relationship between joint angle length change was deduced. compliance, fifth-order polynomial trajectory planning ...

The level adjustment of cable-driven parallel mechanism is challenging due to the difficulty in obtaining an accurate mathematical model and the fact that different sources of uncertainties exist in the adjustment process. This paper presents application of an adaptive control scheme for a cable suspended robot to handle uncertainties in mass and moments of inertia of end effecter. In section I...

damping of a full-scale cable with a pair of passive–on magnetorheological (mr) dampers was tested. a cable of 215.58m long with the first mode frequency of 0.658hz was tensioned horizontally in cable prefabrication factory. two mr dampers were attached to the cable in an angle in the plane perpendicularly to the cable axis in 5m length from the cable anchorage. the applied voltage level was 0v...

In this article, new techniques and technologies have been tried and tested in the installation and commissioning of Roller Home industrial robots, in order to produce a Tiba car with a focus on cost reduction. Due to the fact that press equipment for automobile parts requires a lot of expenses, it was decided to use robots with the same function of roller to reduce costs and increase the q...

This paper addresses the direct geometrico-static analysis of under-constrained cable-driven parallel robots with 3 cables. The task consists in finding all equilibrium configurations of the end-effector when the cable lengths are assigned. An interval-analysis-based procedure is proposed to numerically find the real solutions of the problem for a robot of generic geometry. Three equation sets ...
