Cable-driven parallel robots have a wide range of applications due to its unique characteristics of large workspace and high payload and dynamics. One of its promising industrial applications is high speed material handling allowed by high dynamics of the cable robots. The high speed material handling has been mostly performed by traditional parallel robots, such as delta robots whose workspace and...
A cable-driven parallel robot (CDPR) is a special type of parallel robot. In the past two decades, CDPRs have been attracted a lot of attention since they have various advantages such as large workspace, low energy consumption, heavy payload capability and easy re-configurability. Especially, the greatest strength is that workspace can be expandable easily. CDPRs have enough large workspace inside...
This paper proposes a calibration algorithm for a three degrees-of-freedom (DOF) planar cable-driven parallel robot. The developed calibration algorithm uses a low-cost laser distance sensor to measure the distance between an end-effector and a laser reflector, and also uses the cable lengths measured by using motor encoders. MATLAB simulation results show that using a single laser distance sensor...
Cable-driven parallel robots consist of non-rigid cables which are different from traditional serial robots. The lightweight of the cables allows them to have higher payload and larger workspace. However, the cables may cause significant vibration during operation because the cables are inevitably flexible. Increasing natural frequencies is one of the solutions to reduce the vibration of the cable...
