Design considerations include mechanical aspects such as materials, joints, actuators, sensors, power sources, and electronic components. The design phase also encompasses aesthetic elements for user interaction and appeal.
3. Prototyping:
Prototyping is a crucial stage where a physical model or prototype of the robot is built based on the design specifications. Prototyping allows engineers to test the functionality, feasibility, and performance of the robot in a real or simulated environment. It involves assembling mechanical parts, integrating electronic components, and ensuring compatibility between hardware and software systems.
4. Programming:
Programming is fundamental to a robot’s operation as it dictates how the robot perceives its surroundings, makes decisions, and executes tasks. Depending on the complexity of the robot, programming may involve low-level languages for microcontrollers, such as C or C++, and high-level languages like Python for higher-level functionalities. Algorithms for navigation, object recognition, manipulation, and communication are developed and implemented during this stage.
5. Integration:
Integration involves combining all the mechanical, electronic, and software components into a functional robot system. This includes wiring, connecting sensors and actuators, calibrating sensors, and testing the communication between hardware and software subsystems.

6. Testing and Iteration:
After integration, rigorous testing is conducted to evaluate the robot’s performance, functionality, and reliability. Testing may involve simulated environments, controlled experiments, and real-world scenarios to assess the robot’s capabilities and identify any flaws or issues. Based on test results, iterations and refinements are made to improve the robot’s performance, efficiency, and safety.
7. Deployment and Maintenance:
Once the robot passes testing and meets the desired specifications, it is ready for deployment in its intended environment. Deployment may involve additional setup, calibration, and training if the robot interacts with human operators or other systems. Maintenance procedures are also established to ensure the robot’s continued operation, including regular inspections, software updates, component replacements, and troubleshooting.
