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

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.
