So, I would like to buy a robot that is remote controlled for my husband for Christmas but I know nothing about these things. He trained as an electrical engineer and works in IT and builds computers for a hobby. He is very fond of Raspberry Pi and I wondered if you had any recommendations for a biped/humanoid using a Raspberry Pi, please?
There are not many humanoid/biped robot kits specifically designed for Raspberry Pi in the store, however, you could purchase a hardware-only kit (no electronics) and use Raspberry as the “brain” of the robot in conjunction with a motor driver to control the servos.
On the other hand, if there are other types of robot kits designed for Raspberry Pi, such as cars or hexapods:
Well, it really depends on what he’s into. If he likes playing games then the Pimoroni 10-In Picade Raspberry Pi Gaming Kit would be great, if he likes computer vision maybe a Camera Module with Pan & Tilt kit or a robot kit that includes a camera would be nice. If you have no idea of what he likes maybe some RPi accessories would be useful, like a LCD Touch Screen, or the easiest gift a Certificate so he can choose what he likes.
