The Royal Greenwich Observatory and Liverpool John Moores University, United Kingdom, have joined in a collaboration to produce high quality, ground based robotic telescopes (2.0 to 5.0 m), for use with optical, infrared and interferometric astronomy. This venture has taken the form of a commercial company, Telescope Technologies Limited, to produce the range of Alt-azimuth telescopes. The reliability of the low cost, advanced technology, telescope design will enable remote observing over the Internet. The first two telescopes, currently under production, will see first light in La Palma and India in 1999. This paper covers the concept, design and capability range of the NGAT telescopes.
