my tank bot the begining

hello everyone im new here. Im making my first robot (kinda of) i made a sumovore but it doesnt work :( but about this robot...ive only just started and im running into problems already; treads ripped twice which i have glued back together i have the sprocket above the tread because without this the tread is too loose and the servos i bought arent continuos rotation so what i did was i clipped off the thing that was blocking it from fully rotating this is the only thing ive changed of the servos i hope it will not be much of a problem i bought everything you see at a local hobbytown. now about what this is going to do i cant decide whether to make this robot r/c or not the problem with autonomous is that i want this to treverse obstacles rather than avoid them. but i dont know what to buy or how i would put it together to make it r/c. if anyone knows how to make this robot r/c or both r/c and auto., please tell me. i if i make this auto.,this is how i plan to do it. i will buy the adafruit motor shield and an arduino uno and a ping sensor. please tell me if this is all i need. i know how to put it together but i dont know if i have too much or not enough to complete this.

thank you
