In exchange, Florida received defenseman Jesse Blacker and a conditional future draft pick.
Robak, 24, has played in seven games for the Panthers this season and has not recorded a point.
Anaheim was in need of a defenseman, as Francois Beauchemin is currently on injured reserve with a broken finger and isn’t expected back until late December or early January. The Ducks traded for defenseman Eric Brewer after Beauchemin's injury, but Brewer broke his foot on Wednesday and is expected to be out four to six weeks.
Defenseman Ben Lovejoy is also on injured reserve with a broken finger.
Robak was Florida’s second-round pick in the 2008 NHL draft. After completing his junior career with the Brandon Wheat Kings, the Manitoba native has played most of three seasons in the American Hockey League.
Since 2011-12, Robak has played 42 games with the Panthers, recording three assists and 25 penalty minutes.
Blacker, 23, made his NHL debut for the Ducks on Friday in a loss to the Chicago Blackhawks. The former second-round pick played 15 games this season for Norfolk in the AHL, posting five assists.
