Shipping costs for the large robot I had in mind, are simply too expensive for me to send it to international locations. That's why I decided to shrink the world tour robot and implement no more electronic components than needed to drive around:

A Raspberry Pi Zero WLAN, drive motors, a voltage regulator and a camera. Running two HackadyPrice entries at once was simply too much work in 2016, which is why this robot project did not get the attention it should have. In 2017, my one and only price entry will be the small robot version:
