During the StarKid Summer Season in 2014, Robert helped out backstage during Ani and The Trail To Oregon! In Firebringer, Robert was the Production Assistant and snarl's left paw. He has also worked with Tin Can Brothers, having designed the set for Solve-It Squad Returns.
In 2020, photos were circling in the twitter community in which Starkid actors were edited into the opposite gender, typically called genderbent edits. Robert along with other StarKid actors attempted to join in the fun by retweeting some of these edits. However, the trans community quickly pointed out the issues with such edits and how they play into the gender binary. While the majority of the actors then apologized and deleted the posts, Robert attempted to debate the posting of the edits and ignored the concerns of the trans community as he spoke over trans voices.
Eventually he apologized, however he then later went on to tag a TikTok video he made with the hashtag genderbent showing how he ignored the attempts made by the trans community to better educate him. This led to Robert being accused of being transphobic.
Later, in Robert's 2021 pride tweet he referred to the nonbinary community as "the theys and thems" which was further seen as problematic due to him reducing the community down to merely their pronouns.
This was later furthered by Robert questioning whether it was okay to call nonbinary people "binary rebels" in a tweet on July 14, 2021, this many nonbinary people said that this term made them somewhat uncomfortable and that they'd just rather be called nonbinary. However, Robert later went on to imply that he'd had a positive response from his suggestion and said he would likely use it, once again ignoring the attempts of the nonbinary community to better educate him.
On September 23, 2021, Robert posted an Instagram story admitting to sexually harassing his colleague via unsolicited messages and sexual remarks, leading to major backlash from the fandom.
He later posted an additional explanation of the situation and stated that the original story was posted consensually as a way to resolve the subject with his colleague. Team Starkid issued a statement as well, after consulting with an HR professional, saying that Robert would not be participating in Nightmare Time Season 2, so he could work on bettering himself and rebuilding trust with his colleagues.
Robert befriended the group in 2012 through a songwriting competition for A Very Potter Senior Year with his winning song, The Wizard Duel. He also separately won in the category of costume design, without it being realized by the officiators that he was the same person in both categories. Due to time restraints put on rehearsals, his song wasn't used in the musical. However, StarKid allowed him to sit alongside them at the Leakycon Q&A panel to present his song. Within the same weekend, he also was offered to fill in last minute for Jim and the Povolosat the Beat Kitchen, when Dylan Saunders was unable to make the performance. That following year, Robert was approached to join the cast of Twisted, thus marking his own StarKid debut.
Robert was a big fan of Team StarKid before he won the songwriting competition. In a 2013 interview about preparing for Twisted, Robert said:
"I'm originally from Tasmania, a lonely piece of land shaped like a broken heart that lies just off Australia's southern coast (literally, the opposite side of the globe to the cornflake-shaped Illinois). So, while I had seen StarKid's work online before, even just from a geographical standpoint, I never considered the possibility of being involved with the University of Michigan-originated group
"Less than a year ago, I was just an audience member and have somehow jumped the fence into the other paddock and am performing with people whose craft I respect so highly. What's even more awesome is finding out that they are just as wonderful and inspiring off-stage as well as on."
