Now that the physical robot kits are in the classroom and ROBOTC is installed and activated, you should be ready to build the physical robots for your classroom. One of the best features of a VEX Robotics kit is that they allow students to create a nearly limitless range of robots; the downside of this, however, is maintaining student-created robots in a classroom. To help with this, ROBOTC and the Video Trainer Curriculum support several standard models to help keep a baseline in the classroom.
The first of such robots we will look at is the VEX Squarebot (using the VEX Cortex), one of the standard Cortex models that are used in the VEX Cortex Video Trainer for ROBOTC. The Squarebot utilizes three VEX motors (two for driving, one for the arm), and a wide variety of sensors. These sensors include Quadrature Shaft Encoders, a Sonar Sensor, and a Potentiometer (among others; in total, there are 8 separate sensors on the Squarebot). This model allows for a variety of tasks to be completed and is designed to work with all of the challenges in the ROBOTC Curriculum.
A smaller, different alternative Cortex standard robot is the Swervebot. Like the Squarebot, the Swervebot utilizes the VEX Cortex as its main processor and uses two VEX motors for driving. However, the Swervebot’s small chassis does not utilize an arm. Instead, the Swervebot makes clever use of an Omniwheel in the rear for turning and boasts three Line Follower sensors and a Gyroscope (as well as 6 other sensors, for a total of 10) and is perfect for smaller classroom environments.
Finally, the new VEX IQ platform can be quickly assembled and ready to use in a classroom thanks to the IQ Clawbot standard model. Using 4 motors total (two for driving, one for the arm movement, and one for gripper control), the VEX IQ Clawbot can be controlled either autonomously using the VEX IQ sensors (such as the Bumper Switch and Color Sensors), remotely using the IQ Controller, or a pleasant mix of both, depending on which kit is being used.
