Lab Rover prototypes
HDPR - Heavy Duty Planetary Rover

The HDPR is a rover test platform for high-speed medium payload tests in outdoor conditions (IP4). It has a design consisting of a 6-wheeled locomotion system (6x6x4) with 2 rocker-bogie passive suspension. It is a high-speed medium-size payload carrying rover locomotion platform with a remarkable payload to mass ratio. It is equipped with various camera systems and with a GPS receiver.
ExoTeR - ExoMars Testing Rover

The ExoMars Testing Rover is a half-scale reproduction of the ExoMars rover that mimics the locomotion and navigation subsystems of the real rover. It also incorporates a 5-DoF arm manipulator and on-board sensors for localisation and navigation
RAT - Rover Autonomy Testbed

RAT is an end-to-end technology testing environment for investigating the level of autonomy most appropriate to specific communications constraints. RAT integrates the Lunar Rover Model (LRM), and a control ground station, connected through a communication-tweaker that allows simulation of different bandwidths, delays and jitter.
MaRTA - Martian Rover for Testing Autonomy

MaRTA is the latest developed rover platform and currently under development for its avionics integration (Feb 2017). Designed to mimic a half-scaled ExoMars rover prototype (including six wheel steering) it incorporates the latest design choices and lessons learnt from previous lab developments. MaRTa will eventually replace the ExoTeR rover which has been intensively tested for the last 5 years.
