I believe I wrote something a while back about Anthroform vehicles. They're about the size of an SUV (Vehicle Body of 4) and their quality varies from very basic to highly developed. The most advanced models substitute servos and hydraulics for bundles of piezo-electric memory polymer strands that act like giant muscles.
The closest thing in canon to a mobile suit of armor is the JIM diving suit. The JIM suit can be adapted for VCR and so negates it's movement penalties. However, the rules don't state whether or not the exoskeleton can be used on land. I'd wager it can, however, since the JIM suit is designed to travel at depths well below human tolerances. A mobile suit of armor however, would require consistent charging and behind the scenes logistics in order to be useful.
My previous thread, about custom vehicles, stated that the HAFV (Heavy AnthroForm Vehicle) or Halves were developed for special dropship combat in mixed terrain environments. That is to say, something that can walk, dodge, crawl, duck and climb and still sport heavy vehicle armor in nearly any kind of terrain is very useful. The most extensive testing of Halves was done during a Desert Wars special broadcast, including the new campaigns inside the Gobi Desert.
Currently, a fibre-optic system is being developed for integration in some Halves so that mages can provide full-squad back up for assault. These systems follow the line of thought for Ares' developments in static security defenses. The penalties for using these systems are high, so only talented magicians need apply.
HAFVs use Walker skill for vehicle tests. Melee combat is handled with the Mechanical Arm skill listed in Rigger 3, save for melee weapons, which use their base skills with combat pool/control pool limited by the Mechanical Arm skill. Martial Arts may be used in conjunction with HAFVs, but the vehicle must be both Rigged and incorporate the Smart Materials design option. Other Halves are not articulate enough in scope to incorporate natural body motion in order to use martial arts. Adept powers such as Improved Skill do not apply directly, but they do apply in the case of Improved Mechanical Arms or Improved Walker skills.
Arm-mounted Weapons, with an articulated finger-trigger use their equivalent skill based on their design, combat pool is limited also by the Mechanical Arms skill in this case. For example, the Ares H-A Lord Hunter, is a massive pistol design that looks like the Predator's big mama, uses the pistols skill. Shoulder and body-mounted weapons use the Gunnery skill as before. Ranged weapons held in mechanical hands also gain the benefit of smart-links (if adapted) but not sensor-aided gunnery.
