1. Computer & I/O Controller

The location of the computer will determine the connection method to the I/O controller (USB or Wi-Fi). Any I/O controller that is compatible with ARC is referred to as an EZB (more information below). When designing a robot from scratch or programming an existing robot, take note of these configuration details.

Embedded PC

Embedded PC configurations mounts the computer on-board the robot. The computer can be a laptop, single board computer (SBC) or tablet. Connection to I/O controllers is through USB. Additional USB devices, such as joysticks, cameras and peripherals can be connected directly to the PC on the robot.


Remote PC

In a remote configuration, the computer is off-board and controls the robot wirelessly from your desk. The computer can be a laptop, tablet, or personal computer (PC) with Wi-Fi or an ethernet connection to a Wi-Fi network. Most USB devices that require mounting on the robot cannot be used because the computer is not mounted on the robot.

I/O Controller (EZB) Selection

An I/O controller connects sensors, motors and peripherals to the computer running ARC. When an I/O controller is loaded with firmware that is compatible with ARC, we refer to it as an EZB. Based on the type of computer selection (embedded or remote), I/O controller EZBs will only support specific connection types. For example, an Arduino with EZB firmware uses USB, which requires the computer to be embedded in the robot. An EZ-Robot EZ-B v4 can use both Wi-Fi and USB which supports a remote computer and embedded computer configuration.

Each I/O controller will provide various hardware and custom commands. To identify the capabilities of an I/O controller, ARC provides abstract methods that represent the I/O controller's capabilities. For example, if the connected I/O controller supports a hardware UART, the respective EZB index in ARC will provide hardware UART commands. The capabilities of each I/O controller are determined by the Firmware Capability Manager. An I/O controller loaded with EZ-B firmware will report its capabilities to ARC. If an unsupported command is issued to an I/O controller, ARC will raise an error.

What is an EZB?
An EZB is any robot computer or microcontroller that accepts connections from Synthiam's ARC software to control servos, sensors, and more. Below is a list of compatible products that can be programmed as an EZB. Be sure to check with the manufacturer of the I/O controller for operating specifications, documentation and support.
