Robin Williams' daughter is slated to present a humanitarian award in his honor this week at the Challenged Athletes Foundation.

According to Us Magazine, Zelda Williams, 25, is scheduled to present the "Noble Award" on Friday night and in advance of her presentation she told "Today Show" host Kate Snow she thinks a "lot of people still feel her father's absence."

Robin Williams took his own life more than six years after a lifetime of achievement as a renowned comedian and acclaimed actor whose credits included such films as "Dead Poets Societys," "The Awakenings" and "Good Will Hunting,for which he earned an Oscars nomination.

"For me, especially, it's going to take a lot of work to allow myself to have the sort of fun, happy life that I had," Zelda Williams added. "But that's important. Anybody who has ever lost anyone works very hard to continue that memory in a positive way."

One of the ways Williams has chosen to remember her father is by having a tattoo of a hummingbird drawn on her hand.

"Hummingbirds are fun and flighty and strange," she reasoned. "It's hard to keep them in one place, and dad was a bit like that. Keeping a conversation in one moment was impossible with him. It was a bit like trying to put a bag around a storm and hoping it didn't blow away."

Williams added she consciously choses to reflect on the way her father lived his life as opposed to the fact that he is no longer around.

"There's no point questioning it and no point blaming anyone else for it, and there's no point blaming yourself or the world or whatever the case may be," she said. "Because it happened, so you have to continue to ... live and manage."

One thing Williams admits she does want is to draw greater attention to the disease of mental illness and presumably the bouts of depression her father is rumored to have suffered from.

"I think one of the things that is changing, that is wonderful, is that people are finally starting to approach talking about illnesses that people can't really see," she said. "Nothing happens immediately, but I think we're on our way."
