The mobile assembly robot "Momo" can tackle the whole building process. It is particularly suitable for large area assemblies, where installers face difficult terrain and have to cover large distances. The robot moves to the designated site, supplied with all the necessary photovoltaic modules, assembles the PV unit and moves on to the next one. Listing the benefits, Eberhard Schulz reckons that "with Momo, hardly any modules suffer breakages, programming eliminates assembly errors and fitters no longer suffer from assembly related injuries". The Managing Director of the PV-Kraftwerker GmbH & Co. KG believes that this should equate to an 80 percent improvement in efficiency. Maintenance and cleaning work, as well as system removal, could also be carried out in similar fashion.
The gripper system, equipped with sensors, enables the fully automated assembly of modules on support racks in any terrain. A 3-D camera, mounted on the gripper or a support tool, captures the complete assembly process of the modules and adjusts any deviation from the defined standard with millimetre accuracy. These deviations may originate from inaccurately drilled holes in the framework or slightly offset support racks in open terrain, for example on difficult ground.
Highlighting the level of skill and product knowledge incorporated in his development, Schultz maintains "Momo can cope with tricky terrain and gradients with great accuracy". Special interface software converts the data captured by the sensors into coordinates which Momo interprets. Gripper and camera are coordinated with each other, so that they quickly and reliably capture the position on the support rack, enabling accurate assembly of each module. Subject to the size of a PV power generator, this process may be repeated 100,000-times. In the course of the work, the assembly robot can cover up to 70 kilometres per assembly.
When removing a PV power generator, the assembly system operates in reverse order. This enables modules to be reused, as they will be protected from damage. Another version of the gripper system can also continuously maintain the modules.
The robot, including its digital technology, operates either by battery or generator power. Momo can position modules of more than six square metres and 140 kg in weight. A standard interface is available to change the gripper quickly, making Momo a flexible option for all sorts of applications. In addition, this unique solution from PV-Kraftwerker enables assembly around the clock, regardless of weather conditions.
