DESIGN AND CONTROL OF SMART SERVICE ROBOT FOR OFFICE USE
Project Area of Specialization RoboticsProject SummaryService robots assist human beings by performing a job that is distant, dangerous or repetitive, including household or office work. They typically are autonomous, with different multitasking options. Like all robotic automation, service robots often open the door to greater data collection and analysis for ongoing optimization of all operations
A service robot operates semi or fully autonomously, they are capable to make decisions and acting autonomously in real and unpredictable environments to accomplish determined tasks.
Sales of professional service robots rose by 61% in 2018 vs. 2017, and in 2019 sales of service robots reached $12.9 billion in the world. This includes service robots used for everything from logistics to medical robotics to defense logistics systems. This latest technology is not yet introduced in any office, school, hotel or hospital of Pakistan due to its Expensive rate.
In this project, a SLAM based office service robot will be designed which is capable of decision making, controlling, detecting path, transferring document or items form office to office within department and guiding students/ guests from place to placewith perfect security and in minimum time. An ability will be added to communicate with human and with another robot, therefore, named as “SMART SERVICE ROBOT”. It can be further upgraded in future for hospital/Industry use and can be enhanced to different functionalities and this all is done in minimum amount.
Project Objectives- Selection of components for smart service robot
- Design a CAD model of Robot
- To develop an algorithm for designing department map using LIDAR
- To develop an algorithm for control and monitoring of robot
- To build GUI (Graphical User Interface) for user
- Fabrication and assembly of robot
- Testing and implementation in our department
After collecting data and reading research articles, this project is divided in 5 phases. In first phase, CAD designing of robot is done using SOLIDWORKS; as in figure 1. In phase 2, designing a map of department using LIDAR and Raspberry Pi as hardware and suitable software for that; as shown in figure 2. Once a map is designed, errors are removed from it and robot enters to phase 3 where interfacing of motors with Raspberry pi and designing of algorithm for controlling them is done. As robot start moving with perfect accuracy phase 4 will start where robot is further programmed for making secure transfer of documents/items and guiding users/guests and a GUI (Graphical User Interface) is built for users interaction with robot and finally in phase 5 fabrication and assembling of final body is done as per virtual model is designed in phase 1 for getting attraction from users. After completing all phases, final testing is done and output is analyzed.
This flow chart shows the interfacing of all equipment with Raspberry pi
Benefits of the ProjectThis service robot is beneficial in many offices and institute of world due to
- Its service with perfection.
- Secure transfer of documents/items from person to person.
- Performing task in minimum interval of time.
- Guide user by providing information about department and take them to targeted point.
It is currently implemented/tested in Mehran University but also useful for hospitals, factories, houses, schools. Since service robots are need of everyone in this era.
Technical Details of Final DeliverableThe final product is a hardware which is embedded with RP LIDAR A1 which localize the robot, a pair of DC gear motors, motor controller, touch screen LCD for user interaction with robot and a Raspberry Pi 4b which is CPU for robot, which controls every movement of it and a 12 V DC battery for power supply. These all are assembled in a designed body. And named as SMART SERVICE ROBOT
