OTIS is the EU’s leader and provider of elevators and escalators for markets and manufactures. Through research and innovation, the global company has been pioneering in the development of the safety elevator.

current obstacles

The current scenario focuses on the workstation where the cab door panel hangers are assembled. The operator needs to assemble different kinds of hangers, which vary in size, weight and number of components. To finalise the assembly, the operator requires to have two-side accessibility while lifting and moving around heavy weight. In this context, the main panel must be lifted and repositioned at least twice during the process. Besides that, these arduous tasks need to be performed multiple times.

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.

SHERLOCK solutions

SHERLOCK promotes the use of a High Payload Collaborative Manipulator to handle, rotate, and move the heavy parts 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.

SHERLOCK solutions safeguard also the operators, predicting safety-related aspects.

Finally, SHERLOCK solutions memorise operators’ preferences ensuring a seamless interaction between robotic and human resources while reducing musculoskeletal injuries risks.
