First of all, this is my first robot design and my first Fusion 360 project. TAROVI is a humanoid robot with an always smiling face. He's simply a robot on Segway; the primary mechanism for locomotion. Unlike all those fictional robot designs with no regards to actual practical designs, TAROVI is designed with practicality in mind. Means each of its parts are designed to be physically implemented, for example the joints, the hands etc. The main purpose of TAROVI is to help humans with their personal daily routines at home and work. It can move on any smooth surfaces such as home and office buildings, when moves on two wheels. But if required, TAROVI can be fixed to a track mechanism (triangular) for better stability and mobility, or fixed to somewhere static such as kitchen. TAROVI has a small head enclosing the high resolution cameras, arrays of microphones and other sensors. It has high degree of freedom which allows it to look at anywhere around it. TAROVI speaks through loudspeaker, so it doesn't have a mouth. Instead, there's a monochrome display which will display his emotions. On the chest is a large touch screen interface for humans to interact with it and let's him display things. Inside the torso is the main computer and other crucial parts. The whole body of the TAROVI humanoid is equipped all sorts of sensors including RADARs and IR sensors. Therefore TAROVI is always aware of his surroundings. All the parts above the abdomen can rotate 360 degrees without needing to operate the wheels. Also, the upper part can lean on the horizontal joint which helps it to balance and move on two wheels. It can move forward by leaning forward and break by leaning backwards using the same joint. The bottom part encloses the main battery, motors and charging socket. There are multiple batteries on the robot for power redundancy and as a fail-safe technique. The main Li-Ion batteries provide power for all motors. My favorite part of the robot are the hands and arms which took me the most time. The hands are far versatile than a human hand. It has multiple rotary and revolute joints. The joints were inspired by the Rollin' Justin robot. The arm has five fingers including a thumb. It didn't have a thumb first becasue I didn't know how to actually design a robotic thumb. But later I gave it a try and it turned out to be just great. The thumb can move just like a human thumb and therefore TAROVI can grab things and manipulate just like a human hand would do. Standing about 1 metre tall, TAROVI can move around and help with all your works in homes and offices. But as it moves on either wheels or tracks, it can't climb stairs to move from one floor to another. Robot legs that are similar to human legs are still a thing of the future. I didn't use legs becasue I wouldn't get the satisfaction of a working leg if I just designed without testing. Nevertheless, TAROVI can be fitted with legs for walking. But a solution for making TAROVI move between floors is to use a "transformable staircase". Such a staircase can transform itself from stairs to an inclined plane which the robot is comfortable moving on. The robot can start the transformation and climb when needed. As it is already understood, this is my "concept design" of the robot. I always wanted to design robot and the Design for Robotics challenge gave me an opportunity to make one. My design demonstrates the design of the joints and other mechanisms, but doesn't contain all the actuator mechanisms which need to be considered when building the robot. I designed this in Autodesk Fusion 360. I was a SketchUp user before. It's limited and basic. So I recently made the switch. With the experience from modeling this robot, I can now design anything (parametric) in Fusion 360 now. It's such an awesome tool. The cloud rendering feature was really helpful as I work on a small laptop. I couldn't have rendered it on my machine. Hope you liked my design. Thanks for reading :)
