Key Components of a Cobot
1. Sensors & Vision Systems – Cobots have cameras, lasers, and motion sensors that help them detect humans, objects, and obstacles in real time. This allows them to adjust movements and prevent accidents.
2. Force & Torque Sensors – These sensors allow cobots to detect pressure and resistance while working. If a cobot encounters an unexpected object (like a human hand), it can slow down or stop to prevent injury.
3. AI & Machine Learning – Cobots use artificial intelligence to analyze data and continuously improve performance. Over time, they can learn better ways to complete tasks more efficiently.
4. End Effectors (Grippers & Tools) – Depending on the task, cobots can be equipped with different tools like grippers, welding guns, or suction cups to handle materials, assemble parts, or move objects.
5. User-Friendly Programming – Cobots can be trained using simple software interfaces or hand-guided learning, where a person moves the robot’s arm to teach it a task. This makes cobots easy to use, even for non-technical workers.
6. Robotic Arm Structure – A cobot’s mechanical arm consists of joints and links that provide flexibility and a wide range of motion, allowing it to perform precise, repetitive, or delicate tasks efficiently.
