I have been looking for this show for years now. It was a cartoon and was definitely on Netflix in 2009 or 2010. I remember there was a girl who I think was named Kira and her color was like aqua; she had an older brother whose color was red. Her legs didn't work so she had these boots that would help her walk. There was another girl who had like an ice bird and crystal necklaces and her color was blue. It was on another planet and there were robots and fallen civilizations.
I think what you are searching for is the show https://tvtropes.org/pmwiki/pmwiki.php/WesternAnimation/DiGataDefenders
It revolves around a group of kids that are part of the DiGata Defenders and they use special rocks that have the power to call upon the Primordial beings (aka animal/dinosaurs) to fight with them. The main character is starts to merge with his animal and is thinking of himself as a monster until someone helps him. One girl is unable to walk and has to use special boots and is always helped by her big brother.
