CALPAK is one of the major players in the market of solar panels and especially domestic water heating using solar thermal collectors. Constantly aiming to develop and progress. CALPAK aims to promote renewable sources of energy in Greece through innovation, recycling and know-how in the area of renewable energy.


current obstacles

The current scenario focuses on the workstation where the new line of solar thermal collectors are assembled. The operator needs to assemble different variants of thermal collectors, which vary in size and weight. To finalise the assembly, the operator requires to have two-side accessibility while lifting and moving around the heavy thermal collectors. These arduous tasks need to be performed multiple times during a shift.

Considering all these aspects, the employment of operators with physical restrictions is not feasible. Chronic pain problems are also generated, such as back pains and hand tendinitis, as well as a higher fatigue level.

CALPAK use case - current situation

SHERLOCK solutions

SHERLOCK promotes the use of a High Payload Collaborative Manipulator to handle, rotate, and move the heavy solar thermal collectors and present them to the operators in the most convenient way to perform the various assembly processes.

The high payload robot handles the heavy payload while the operator focuses on lightweight assembly operations. Empowered with AI, onboard sensing systems monitor the actions of the operator, ensuring the proper assembly by checking the sequence of the diverse operations.

Furthermore, the operator is assisted by AR visualisations indicating the next instructions in the assembly process.
