i can't watch the video thru this link but from what i gather its like the boston dynamics robodog but with wheels for feet. adding wheels to robot legs is probably the Coolest design choice possible. it's ingenious really, you need something to be the 'foot', and that something might as well have built-in shock absorption and also spin to provide a traversal option that circumvents the major disadvantage of legged vehicles, speed on flat ground, without removing the capacity to use the legs to traverse more complicated terrain. skating quadruped robots might even handle terrain at speed that a car or traditional UGV might not ever be able to handle, using the agility provided by legs to position wheels. i want my car to be an oversized one of these so badly. i can't wait until someone makes a useable larger bipedal version of this, make my skating mecha dreams come true!
frankly tho i would just put the wheels on the main chassis separate from the legs for simplicity's sake, used with legs folded more like a traditional wheeled craft, so the wheels are still useable if the legs break and you don't have to put electric motors or wiring or whatever in inconvenient places through the legs. it would lose a little agility without 'mech skating' but i think it might be worth it for reliability/ease of manufacture/repair.
the Atlas is basically too slow (48 km/h or so) to be useful in mechwarrior 5 imo, you get better performance if you take a Battlemaster (about 64 km/h) and move all its rear armor to the front. set the 4 medium lasers in the chest to chainfire instead of all at once and you will have excellent damage output without a risk of overheating, while your left arm MGs blast away with negligible heat buildup and your shoulder SRM can be saved to finish off damaged enemies. (LRMs are heavy and useless against lighter/faster enemies since they will close to within your minimum range, they don't even do great damage ime at their optimal range unless your entire AI squad is LRM carriers and you are their spotter)
also i hate the transparent cockpit designs on battletech mechs, they should either have remote operated camera pods or tank-style periscopes unless they are particularly lightweight imo. the setting makes the mechs out to be ancient storied machines that no one knows how to build anymore, passed down through generations of space feudalism and kept barely functional, but they all look like freshly mass produced clean 1980's angular space robots. they should have like clan banners and family names and engravings and retrofit low-tech parts and stuff if the lore is meant to be at all meaningful.
