Nick is an inventor.

R7 is one of Nick's robots. As the name suggests, he's the seventh robot Nick created. He moves around using his wheel and is round. As seen in all episodes, he spends most of his time chasing Watt, pretending to be a cat.
Watt is Nick's puppy

Ro
One of Nika's robots is a pink female. She has a distinct role—for example, she often acts as an assistant with technical tasks or information retrieval. She's a reliable companion on the team. All the robots, except Mi, are in love with her.

We
Another robot from the team, a very small one. Mi also has its own specialization—she excels at tasks that require precision, attention to detail, or, for example, working with small parts. She's friendly and responsive, but very small. Simply put, she's a baby robot.

Megatons
This green robot is specially designed for heavy lifting. Its body is tilted diagonally, and instead of legs, it has tracks, allowing it to move confidently. It has a "good-natured" personality: it's strong and sturdy, yet inquisitive and playful. One episode shows it learning to control its strength to avoid breaking things.

Plateau
Plato has his own unique role on the team; he's orange. He often takes on functions related to situational analysis, planning, or working with visual information (for example, helping with maps or diagrams). The robot is a nerd.

Turbo
This robot is responsible for speed and dynamics. It's perfect for tasks that require quick movement, reconnaissance, or action under tight deadlines. It's energetic and proactive, a cheerful yellow robot.

Gamer
His specialty is anything related to games, logic puzzles, and digital technology. He helps the team solve puzzles, program, or interact with virtual worlds. He's also a cheerful person, and is blue in color.

Pico
Pico has its own functions—for example, it can be useful in tasks that require dexterity, working with small mechanisms, or sensory tasks. Friendly and always ready to help, Pico is an aesthete and artist. This robot, similar to a robot vacuum cleaner, flies like Turbo, and has built-in paint. It's purple.

Nick
The protagonist is a talented inventor. He designs his own robot assistants and imbues them with artificial intelligence. Together with his team, Nick explores the world, conducts experiments, solves various problems, and learns new things—including about science, technology, and friendship.
