I have designed a series of mini articulated robot / mech with interchangeable body parts and, they stands 2 - 5 cm tall, consisting 20 - 100 parts forming complex universal mechanical joint and interchangeable arms, legs, pelvis, foot, weapons and attachment. You can take off the arm leg pelvis weapon or the whole upper or lower body and change it with the other robot / mech create unique and interesting combination.
I have little experience in playing board game, my friend suggest they could be fun to play as a character in game. I figure the best way to find out is to ask opinion from game designers and players. So any feedback are welcome.
Here are some photos, they called Neurobota
They are made with 3d printing
