= Minibot Challenges! [[Image(http://gloimg.gearbest.com/gb/2015/201503/source-img/1426123371018-P-2469204.jpg, align=right, width=200)]] After you have completed the Arduino Fundamentals track, talk to a lead about the following challenges. Everyone will begin with bumper cars. After that, you can do any number of them, time permitting, in any order, although they range in difficulty. === Materials, Supplies, Equipment * Arduino Uno '''CONSTRUCTION''' * minibot chassis * wheels * batteries & battery cases '''SENSING''' * infrared (IR) proximity sensors * infrared (IR) remotes & remote receivers * ultrasonic sensors '''ACUTATING''' * motors/motor controllers * LCD display screens There is always a potential for us to obtain other sensors/actuators as well, so if you have an idea, ask! == Line-Following Maze Your goal is to make it from the start of the maze to the end of the maze by following the black lines on the ground. We will not tell you what the maze will look like. Note that you will need a way to sense the line (IR LEDs/Sensors or similar - discuss this with a lead or a mentor). For more information see [http://circuitdigest.com/microcontroller-projects/line-follower-robot-using-arduino here]. == Sumo Bots! If you haven't heard about this before, Sumo Bots are robots that play the ancient Japanese game of Sumo, where players must try to push their opponent out of the ring (without leaving the ring yourself). The dimensions for the ring will be below once it's finished. The ring boundaries will be marked with black tape. A robot will be considered out of the ring if all of its points of contact with the ground (i.e. the wheels) are outside the black lines. == 360 Mapping & Navigation Use the Ultrasonic sensors to scan the environment in order to navigate along the edges of the room. For an added challenge, store and display the distances of points 360 degrees around the robot in a graphical map (Processing, Java Swing, openGL, etc). See this [https://www.youtube.com/watch?feature=player_embedded&v=QqdgFu96KnA video tutorial]. == Bumper Cars Using a remote control, design a robot that is capable of playing a game of bumper cars. There are different drive systems you can consider for this. == Teeter Totter Using an IMU (Inertial Measurement Unit), balance the bot on a teeter totter board. Once it is fully balanced it should stop and signal its success using an LED or LCD display screen.
