Emms and Robertson won Olympic silver in Athens in 2004
Athens mixed doubles silver medallist Nathan Robertson has been included in Britain's six-strong Olympic squad after overcoming an ankle injury.
The 30-year-old, who will again partner Gail Emms in Beijing, underwent surgery last month but has resumed training.
Emms said: "A brilliant surgeon cleared out his ankle and Nathan was walking in two days - so all is looking good."
Donna Kellogg and Anthony Clark compete in the mixed doubles, and Tracey Hallam and Andrew Smith play in the singles.
Robertson and Emms, ranked sixth in the world, won the mixed doubles world title in 2006 beating Kellogg and Clark in the final.
But they have struggled for form since, losing in the semi-finals at the All England Championships and Europeans this year.
Emms added: "Nathan has had an ankle problem for 18 months or so and we've competed through it, so to be fair, we've actually done pretty well.
"I want to achieve gold in Beijing but I also just want us to go out there and play well because I know when we play well we can beat anyone."
Meanwhile, Clark and Kellogg, ranked eighth in the world, are current European mixed doubles champions and confident of making the podium in China.
Kellogg told BBC Sport: "A medal is our goal. There is no point just going for the experience, this is my third Olympics and Anthony's second.
"We know what to expect and the goal is to win a medal and we'll be a little disappointed if we come away without one."
Emms and Kellogg will also compete in the women's doubles where they are ranked seventh in the world.
It is a format they have had success in in the past, winning the 2000 and 2006 European Championships.
In the singles, Hallam is 14th in the women's world rankings, and Smith is 31st in the men's rankings.
Andy Wood, the squad's team leader, said: "After a long and demanding qualification period we are delighted to have qualified such an exciting team.
"The blend of youth, experience and personalities ensures a dynamic Team GB badminton environment.
"You can be sure that this team will be ready and competing optimally to be amongst the medal meltdown."
