Ziggy: Realie, 4 bar 2400psi nitrogen flipper with six wheel drive, unsure about the rest. Aaron will probably come along and fill in the gaps though

Skink: Featherweight HDPE armoured full pressure flipper - http://www.roamingrobots.co.uk/?pages=robot&id=1074http://www.roamingrobots.co.uk/?pages=robot&id=1074 for details.

Hope that helps
