Design and development of biped humanoid robot for social interaction
Project Area of Specialization RoboticsProject SummaryThis project promotes the idea of a Human-Robot Interaction (HRI). Robotics is the main essence of the fourth industrial revolution (4IR). The technology adopted here serves to enable safe and reliable human-robot collaboration in real-world scenarios in order to enhance the quality of life. Its initial design was 45 cm long and had a steady plan that was motivated by a generally made project at Haptics lab. Aspired by our small prototype we started working on the calculations for the materials and motors of our robot whose height has been estimated at about 4 feet 11 inches. The main purpose of this project is to build a prototype for future research to be done in the field of humanoid robotics in Pakistan and create a benchmark for the first time in the country. It is a highly scalable project and flexible enough for future changes.
Project ObjectivesThe goals and objectives of this socio-interactive humanoid robot are sorted and arranged in the following segments.
-
To design and build a robot that would be able to walk.
-
It will be able to balance its weight on bipeds.
-
Designing a user-friendly web interface for controlling movements.
The first objective focuses on the manipulation of the robot between two points A and B as per the instructions given by the operator while avoiding all obstructions in its way. The second objective focuses on the control of a walking robot, that is to guarantee a suitable ground reaction force to keep the dynamic balance. Whereas the third objective focuses on smart interfacing and safety mechanisms.
Project Implementation MethodThis project was initialized with a 45cm prototype which is quite common but our primary objective was to design and build an actual human-looking robot. So, using our prototype, we decided to scale it by three times in length and breadth while choosing a 1mm sheet of L-shaped Aluminum as material due to its lightweight and high strength. Using the density of aluminum metal, we estimated the sizes and nominal values of our motors. We did our fabrication work for the bipedal. Bipedal is the most important and extremely complex part of the humanoid robot as it contains all the complexity involved in the process. We have worked on the fabrication of our robot in local and university workshops using angled iron. After the completion of the legs, we added motors to the system and then will start working on the upper part of our robot.
Benefits of the ProjectRobots, in the future, have the tendency of becoming the biggest asset to any business. They are considered to be the latest and most professional form of completing work whilst saving money and achieving high efficiency. As far as the socially interactive robot is concerned, it will avoid the risks of depression, anxiety, and loneliness in children and old-aged people. For households, it will act as a volunteer worker, doing the chores as programmed. For commercial use like offices and restaurants, it will act as a 24/7 employee without demanding a salary and doing twice the work as a human employee would do with increased efficiency, precision, and energy. Since it is a biped robot so it can do tasks just like a human in situations where it feels impossible for a human to go for example if there is a fire it can do rescue operations with much more efficiency.
Technical Details of Final DeliverableDesign and development of a walking bipedal that would allow the robot to be able to look, walk, and work as an actual human being have always been challenging tasks. Deciding the size of its motor, its center of gravity, and stability has been a great hurdle. After working on a smaller prototype, we are able to calculate/ estimate the dimensions of human size robot. The mechanical and control parameters that will be used are an aluminum sheet which is 1mm, sensors for feedback, servo motors, microcontroller, camera, raspberry pi, and motor driver. As per our desired application, there will be a total of seventeen motors to be incorporated in the robot (Humanoid) that will be controlled using the Arduino Mega microcontroller.
