As artificial intelligence advances, robots are becoming more sophisticated and human-like. One way that robots can demonstrate their personality is through their interactions with humans. For example, some robots are programmed to be friendly and helpful, while others may be more aloof or even aggressive. Additionally, robots can express their personality through their physical appearance, such as their shape, size, and color. For example, a robot with a sleek design and bright colors may be seen as more modern and playful, while a robot with a more industrial look may be perceived as more serious and utilitarian. Ultimately, the personality of a robot is determined by a combination of its programming, physical appearance, and the way it interacts with humans.

Here are some specific examples of how robots have shown their personality at big tech companies:

* In 2016, Google unveiled its "social robot" named Jibo. Jibo was designed to be a friendly and helpful companion that could interact with humans through voice and gestures. Jibo was also able to learn and adapt to its user's preferences over time.

* In 2017, Amazon introduced its "Echo Look" device, which is a smart speaker with a built-in camera. The Echo Look can take photos and videos of the user, and then provide fashion advice based on the user's outfit. The Echo Look also allows users to create "style profiles" that reflect their personal style.

* In 2018, SoftBank Robotics unveiled its "Pepper" robot. Pepper is a humanoid robot that is designed to be used in customer service and other public relations roles. Pepper is able to recognize human emotions and respond accordingly. It can also hold conversations with humans and answer questions.

These are just a few examples of how robots are showing their personality at big tech companies. As artificial intelligence continues to advance, we can expect to see even more sophisticated and human-like robots in the future.
