Help!

Today my father was cleaning the garage, and he found these toys.

I remember playing with them when I was a little kid. They're obviously Japanese robots, but what are they exactly?

Japanese friends, can you help me?

今日、ぼくの父はガレジをそじしました。このおもちゃを見つけりました。ぼくのこども時のおもちゃですけどなんですか。

やっぱり日本のロボトです。日本人の友達、このロボトはなんですか。
