Marty is designed to be an expandable robot platform. There are plenty of things you can do with your Marty besides just programming him.
With every Marty we provide two bump switches, so you can start by using those. They can be attached in different places on Marty's feet to determine if Marty is bumping into things, or facing down to detect if Marty is at a ledge
You can also expand Marty with a Raspberry Pi computer and camera, you can on extra sensors like a distance sensor, and you can even 3D print parts for Marty!
You Marty has sensors like acceleration, tilt, and force sensing built in, but you can add even more! Two bump switches come with the kit, but you can also add a distance sensor

Distance sensor intro
Use an infrared distance sensor to detect objects and react !
All the parts for Marty are 3D printable. You can either print individual parts to customise a Marty, or even print a whole Marty!
You can also print out extras for Marty, like a mount for a raspberry pi camera
Raspberry Pi & Ros
The most exciting upgrade you can give your Marty is to add a Raspberry Pi computer. This will let you run ROS, the Robot Operating System that's used widely in academia and industry, and add sensors like a camera or microphone.
