Normally pi-top sells their pi-top  as an armor case for your Raspberry Pi, with a battery and power management system. They sell this product for only $99.95. If this interests you, pick that up Here.
However, they worked on the product for six years, including testing and fine-tuning, and they are now launching now the pi-top  Robotics Kit!
You plug in the pi-top  into items from this kit. Things like:
The expansion plate is metallic and made of plates and brackets. You can easily snap the pieces together in their rivets points, giving many different ways to create the device.
Some suggestion from the company is a vehicle, a drone, or a robot!
If you were a huge fan of LEGO and their Technic set, then this might seem a little familiar, but a bunch of steps ahead!
