Hardware Nodes Documentation
This page describes the hardware nodes that are present for the 1718 Mars Rover project.
The project contains the following nodes:
IRIS node
This node serves as the computer's main interface with the hardware in the rest of the Rover. It features 10 RS485 ports and a Teensy Microcontroller that allows it to perform most of the control and sensing features for the Rover.
Motor node
This node controls the motors that turn Rover's wheels.
Tower node
This node is placed outside of the main electronics box on the chassis and collects data from various sensors.
Tower alt
This board acts as an alternate for Rover's Tower Node when both of the boards we had didn't work. It really just breaks out a Teensy 3.2 to a few different connectors.
Grasp Node
Controls 4 DC motors with quadrature encoder and current feedback. Has four analog inputs intended to be used with force resistors.
Science Node
Powers, and comunicates with the Soil Probe via RS-485. Uses simple logic to power a drill motor (24V,5A, full forward, full back, stop). Outputs 5V to power a digital camera. Sends a signal to the didgital camera to control shoot and zoom.
