Asimov's Three Laws of Robotics:
A robot may not injure a human being or, through inaction, allow a human being to come to harm.
A robot must obey the orders given to it by human beings, except where such orders would conflict with the First Law.
A robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.
Abstract
The objective of this Senior Design Project was to design and build a humanoid robot capable of various actions. The robot, called TigerBot, has been designed to be a platform for future use and work, capable of being modified easily. This project is to serve as a starting point in the progression towards a mobile robot capable of giving campus tours autonomously. A few of the main goals include the ability to walk, balance, and take voice commands.

Design Process
The first step in the design process was the design of the mechanical body through the use of CAD programs. Additionally, the search for appropriate electrical components yielded the current set of devices. The three subsystems of the TigerBot are the mechanical body, electrical hardware, and programming environment. The mechanical body consists of 22 servos connected with various aluminum rods and plates. The main electrical components used include a RoBoard embedded computer, custom power distribution board, and servo controller board. Additionally, a voice recognition module, accelerometer, gyroscope, wireless adapter, and multiple ultrasonic sensors and infrared sensors are utilized. The programming environment consists of the ROS operating system.

Results
Currently, the TigerBot is capable of standing on its own as well as performing various actions involving the arms. Additionally, the TigerBot can stand on it's own while balancing. The TigerBot is 48% taller than Robonova, but cost only 40% more.
