Case Studies

Humorous Story 1: The Unstoppable Robot

A manufacturing company invested in a new industrial robot to automate its welding process. However, the robot kept getting stuck due to a misalignment in the conveyor belt. The engineers spent hours troubleshooting before realizing that the robot was made of a magnetic material and was being attracted to the metal conveyor belt!

Lesson Learnt: Pay attention to the magnetic properties of materials when designing and installing industrial robots.

Humorous Story 2: The Robotic Taster

A food manufacturing company used a robot to sample their new products. However, the robot's taste buds were so sensitive that it started rejecting all flavors except for the one ingredient that was absent in the current recipe: dill pickles.

Lesson Learnt: Consider the sensory capabilities of materials when designing robot components, especially when dealing with food products.

Humorous Story 3: The Dancing Robot

A university research team created a robot that could perform complex dance moves. However, the robot's joints were made of a material that was too flexible, causing it to wobble and "dance" erratically.

Lesson Learnt: The mechanical properties of materials play a crucial role in the performance and stability of industrial robots.
