Subsystems are parts of every FTC robot created to complete specific tasks. Subsystems are considered separate from the drivetrain because they control the functions of the robot rather than the movement. For example, the drivetrain allows for movement around the field, while subsystems complete specific parts missions through grabbing, lifting, collecting, pushing, and more. Each year the game changes with the theme for that year. Because of this, new subsystems are made each year to best fit/complete those missions.
There are many different types of subsystems. There are overarching groups for subsystems that are organized by the task they accomplish, for example, grabbing or lifting. Then within each group, there are specific subsystems that can be built.
- Vertical Wheels
- Horizontal Wheels
- Conveyor Belt: Vertical and Angled
- Spinners/Tubing Intake
- Materials for Collectors
Planning for Subsystems
There are many different part providers and vendors that specialize in parts for different types of subsystems. Finding the best part for the job is very beneficial for teams. Whenever building or implementing a subsystem for the robot, always make sure to plan out everything by using a strategic approach to avoid as many potential complications as possible. Subsystems will also take much less time to get working properly if they are planned out ahead of time. Lack of planning can also cause issues such as problems with weight distribution. If the weight distribution is uneven, there can be inconsistencies with strafing and the ability to drive straight. However, strategically assembling the robot and the different subsystems will make sure the weight distribution is even since subsystems take up a lot of weight and space on the robot. In conclusion, make sure to always plan out everything within your robot to avoid any complications with driving, space, and more.
