The XM157 - An un-manned, automatic, offroad, ground drone that targets nearby players and objects if desired. The video shows two version of this, 1 of which is a more stable version that smoothly turns corners at the expense of speed, and the other one (with orange wheels) has anti roll (stopping it from toppling over on harsh corners), in accordance to the gyroscope the drone will speed up if the pitch of the vehicle simulates the effects of going uphill acting as an automatic offroad mode and overall has a higher engine speed for maxium performance. I soon plan to make it avoid nearby props if they are in the way acting as a simple A.I. If this video gets popular enough i may make a tutorial for you guys. Show some feedback in the comments. Enjoy!
