This week on Tech Weekly with games editor Keith Stuart we take a look at an emerging trend in games, where smartphones and cutting-edge robotics are used to create more socially inclusive and dynamic games.

Joining Keith is Guardian writer Alex Hern; Iain Simons, director of the GameCity festival; and Jonathan Smith, games producer for Lego.

The panel discuss why the screen is only a part of the gaming experience – and why small-scale, cheap robotics will open up a new world for developers.

Also this week: Guardian tech writer Samuel Gibbs meets Ian Bernstein, co-creator of the robotic toy ball the Sphero, to find out about the evolution of the robot in gaming.
