Alpha - 2015 Control System

TheRobettes.com

Alpha Test Porject• The Robettes spent the fall season setting up

and trying out the new components and features of the 2015 Control System.

• In November, representatives convened with other testing teams New Hampshire to talk about problems and solutions, and play some matches on the field.

Overview

• New Power Distribution Panel (PDP)

• New Voltage Regulator Module (VRM)

• New Pneumatics Control Module (PCM)

• New roboRIO controller (replaces cRIO)

• PCM and PDP monitoring circuits connect to roboRio through improved native CAN bus

Voltage Reg Modul

e

roboRIO• Combines cRIO + Modules + Digital Sidecar into a single

small unit• OS: Linux with real-time extensions• Processor: Dual-Core ARM Cortex-A9 at 667 MHz• Memory: 256 MB RAM, 256 MB flash storage• Size 5.7 in x 5.6 in, Weight under 12 oz• IO: 10 PWM, 10 digital I/O, 4 relay outputs, 1 SPI, 1 I2C, 4

analog– Expansion port adds even more

• 2 USB ports• Native CAN bus• Integrated 3-axis accelometer

roboRIO

•

Voltage Regulator Module (VRM)• Ensures constant voltage to sensors, camera, etc.

– Takes battery 12V and provides regulated 12V and 5V– Ideal for custom sensors, camera power, etc.– (radio now USB powered)

Pneumatics Control Module (PCM)

Provides all-in-one pneumatics system control: pressure switch input, compressor relay output• 8 Solenoids outputs• Uses CAN• Button connectors

Power Distribution Board

• Smaller • only 8 20-30 amp wago ports (fewer, but less are needed)

• CAN capability– Channel monitoring (unclear at present whether just voltage or both

voltage+current)

Radio

• USB • Smaller size

Programming• LabVIEW, C++, and Java continue to be supported• For Java & C++, much of WPILib will be unchanged:

Removed: “module” number in constructors (as modules no longer exist)New classes for new features

• For C++ -- Development environment changes from Wind River Workbench (custom version of Eclipse) to latest Eclipse (currently Kepler)

• For Java -- Development environment changes from NetBeans to Eclipse.
