Technical overview of the Edison V2 robot’s components

Looking to learn all the nitty-gritty details about what makes Edison the robot tick? Well, here it is!


Edison is programmed using any of the Edison robotic programming languages.

Programs are downloaded to Edison using the EdComm cable. The EdComm cable is the special cable used to download programs to Edison robots from any of the Edison robotics programming languages. The EdComm cable is how you connect your Edison robot to a computer or tablet. The EdComm cable plugs into the computer’s headphone jack and carries a pulsed audio signal to a high-efficiency infrared (IR) LED. The IR LED converts the pulsed audio signal into light that is received by Edison’s line tracker phototransistor and loads the program into the processor. 

Sensors and inputs

Obstacle detection: Infrared using 2 IR LEDs (top front left and right) and IR receiver module (doubles as the IR data comms and remote-control receiver)

Remote control: IR receiver module (which operates at 38kHz) allows Edison to learn IR codes from most standard TV/DVD remote controls

Infrared data comms: IR receiver module (double as obstacle detection sensor and IR remote receiver)

Line tracker: Red LED and phototransistor (doubles as barcode reader and programming port)

Light sensors: 2 phototransistors (top front left and right) 

Sound sensor: Piezo transducer (doubles as sounder)


Drive: Differential two-wheel drive system with wheel encoders (Edison V2.0 models)

Infrared data comms: 2 infrared (IR) LEDs (double as obstacle detection sensor)

Sound: Piezo buzzer (doubles as sound sensor) 

Lights: 2 red LEDs (Front left and right)


Freescale 8-bit MC9S08PA16VLC


Battery: 4 x AAA (UM 4) Alkaline or Ni-MH

Heads up

The Australian Federal Parliament has passed a law that extends goods and services tax (GST) to low value imports of physical goods imported by consumers from 1 July 2018.

This means that all customers purchasing Edison robots and accessories with an Australian shipping address must now pay GST. The GST will be automatically added to your purchase and show as a line item on your invoice.

We've detected that you are in Australia, so we wanted to let you know that we have changed your settings to view our Australian site, which displays GST inclusive pricing.
