Abstract
The commissioning of a high speed parallel robot such as the ABB Flexpicker Robot into the industrial environment provides greater flexibility in picking, packaging or palletizing tasks. However, current configuration of this robot only allows up to four-degree-of-freedom (DOF) which restricted its function to perform simple or complex automated assembly task. Therefore, the possibility of increasing one additional degree-of-freedom for the parallel robot was investigated. By attaching a flexible vacuum hose to the robot’s end effector, it can be controlled by using a servomotor that can manipulate its angle of suction up to 90 degrees. With this new configuration, one DOF has been introduced for this robot. Several tests had been conducted to evaluate the flexibility and performance of the end effector which includes varying loads and angles. From the analysis, it is found that the end-effector can lift weights up to 1kg due to sufficient vacuum pressure; however, it could perform bending up to 90 degrees for maximum load of 600 grams only.
Highlights
Parallel robots are a relatively young type robot that has been developed over 25 years ago and has been implemented in productions for about 15 years
A majority of the highspeed robot is based on delta design which has been developed in 1988 by the Ecole Polytechnique Fédérale de Lausanne (EPFL)
According to the obtained result, the lifting force induced by the ABB FlexPicker is sufficient to hold the maximum weight of 1 kg
Summary
Parallel robots are a relatively young type robot that has been developed over 25 years ago and has been implemented in productions for about 15 years. Parallel robots are robots with closed-loop mechanism and consist of three or more rotary or prismatic axes that functional parallel to each other. Parallel robots are designed for high-speed applications, manufacturing, packaging, material handling and assembly purpose. A majority of the highspeed robot is based on delta design which has been developed in 1988 by the Ecole Polytechnique Fédérale de Lausanne (EPFL). Delta architecture robots are highly dynamics due to its lightweight and parallel design. The first commercial Delta robots were produced by BOSCH and ASEA Brown Boveri, (ABB) companies. ABB FlexPicker is the most sold and fastest commercial parallel robot in the world today [1][2]
