According to some sources, Robert was born at Writtle in Essex.
 
After John Comyn betrayed an agreement with Robert to make the latter king of Scotland, Robert set up a meeting with him at Greyfriars Church. After confronting Comyn with a letter to the English king, Bruce lost his temper and stabbed him. Comyn's uncle, Robert Comyn, tried to kill Bruce with his sword, but Christopher Seton, the husband of Christina Bruce, struck Robert Comyn down. According to legend, Bruce left the church and told his men "I doubt I have killed Red Comyn," to which one of his men replied, "If you have doubts, I'll make sure," and went back in to finish the job.
 
Robert was crowned by Isabel, Countess of Buchan on 27 March 1306.
 
Following the battle of Bannockburn, Robert was distressed at the death of his second cousin Gilbert de Clare, Earl of Gloucester, and kept vigil over Gilbert's body for part of the night. He subsequently paid for the body to be shipped back to England.
 
Robert died of leprosy.
 
Robert's heart was laid in Melrose Abbey, after Sir James Douglas had been killed in battle in Spain, trying to carry the heart to Jerusalem.
