This is your generic and cliché trope where the MC will always try to do something for the sake of justice/good but he doesn't have the required strength to do so. His actions related heavily to his feelings, he went straight thru a dangerous situation and always ended up saved by random pedestrians. He's so gullible that you can practically sell him to a slave master, he'd straight up believe that you're giving him a harsh training and he'll overcome it eventually, sigh.
Kanata as the main character had little to none character development on this first season. He shouts at people when he doesn't understand anything that is going on, he closes his eyes like a kid when he is in danger, he doesn't want to be treated as a kid yet he gives his robot the same treatment. Talk about irony eh?
The only thing I've found entertaining is the 'Team Rocket' characters for this series, Range and Dolce. Both of them are made for each other to be honest. They act goofy, they clown everybody and their chemistry is perfect, it doesn't feel forced. On the other hand, the MC and his 'hardships' felt like the writer is involved on the story but gave no development to him. He was influenced by the decisions of the people around him, he seldomly makes decision to do something BY HIMSELF except performing machines' repair and maintenance. It's like watching a zombie, taking orders from everyone and when he's not, he's back to doing zombie stuff.
What I meant by "the writer is involved" is, the people around the MC always initiate something to make the MC do stuff. He was 'spoon-fed' so hard, that some characters had to find a way for him to fight important figures or bosses even though he had no strength to do so. But, it's not a problem, plot armour prevails for this trope.
But, I'll have to give credits where its due, props to 8bit studio for the excellent CGI and animations.
