Business CITY BEAT Anthony Marx Premium Content ROBOTICS REBOUND Just three months after his robotics firm collapsed, David Baird is back flogging much the same equipment under the guise of a different company. The Sunshine Coast-based entrepreneur kept busy this week spruiking one of his six-wheeled unmanned ground vehicles at the Land Forces military expo in Brisbane, which wrapped up Thursday after three days punctuated by anti-war protests.

They also learned from a sign tacked to the wall that the business had received unspecified federal government financial support to attend the event.
