Please start by completing the entire Android Studio Tutorial if you have not used Android Studio to create an OpMode previously. Note: This codelab is not intended for those who are completely new to the use of Android Studio for FTC robot programming. How to create an autonomous op mode that uses Navicat.How to install Navicat into your FTC Android Studio project.How to perform tuning to determine your robot's configuration values using the Road Runner Quickstart project.In this codelab, you're going to go through the steps required to setup Road Runner for your robot and create an op mode for an FTC robot that uses the Navicat library for navigation. For the purpose of this codelab, the drivetrain motors must have encoders which are properly configured, also. What does Navicat do?īy using Schrodinger, Nyan, & Navicat together, you can create autonomous op modes which have a powerful, easy-to-use, reliable navigation ability which is accessible as a subsystem and is part of a state machine framework which makes it easy for robot components to perform complex operations while navigating.Ĭurrently, Navicat works only for robots with a mecanum drivetrain and no odometry free wheels.

You can learn a lot more about Road Runner in this tour. It also uses motion profiling to constrain the velocity, acceleration, and jerk of the robot to reduce wheel slippage and wear on robot parts. Road Runner figures out how the motors should be powered to follow the path, and computes the position of the robot using odometry in order to make adjustments according to the actual speed and travel of the wheels. With Road Runner, you can specify complex paths for your robot to travel including start and finish orientation and position. With a good navigation system, you can focus more on giving the robot instructions on where to go and what to do instead of how to get there. Navigation means a robot's ability to know its location (also called localization) and move to a target location. It also uses the awesome motion planning library Road Runner, which was created by Team 8367 Acme Robotics. Navicat builds on two other libraries we have created: Schrodinger for state machines and Nyan for subsystems. Navicat is a Java library for use in FTC robot control systems that helps with navigation. Navigation for FTC Robots with Road Runner & Navicat
