Ya no I dont plan on going that big I just want to make one for fun. Not really planning on competions just wanting to get involved and learn stuff. I plan on 5lbs or less
In this corner weighing in at 90 bounds… WALTER!! Designed by Chris the Carpentner, with a niffty Transmittor. In the other corner, weighing in at a unknown weight for the time. Makeitcool’s BATTLE BOT, which we have little clue about, but would like to know more about.
Ok I know I can get better motors and so on but lets go back to what I said earlier. Will my motor and BEC work for what I want? thanks for all your help patrick
A BEC is just a voltage regulator. RC people use them to supply 5v to their RC receiver and servos. What kind of motor controller are you going to be using. A brushed ESC or some other controller? What battery will you be using?
As Patrick said, those motors would be for a smaller robot.
Regarding the BEC, you don’t necessarily need one, but you do need some sort of power for your motors and electronics. The BEC you linked provides 5A @ 5V. Your two motors have a stall current (maximum load) of 1.6A each. So the BEC would certainly work, but might be overkill.
Check out OddBot’s post on voltage regulators, which may be a lot less expensive. You need to determine what the overall load of your robot (power for motors, servos, electronics, etc.), so you can design or buy the appropriate power source.
oh ok so I might not need a BEC? I have a 6 or 7.2 battery at the moment for the reciever power and like 3 servos on one project but I wouldnt use them here. Ill try to get everything I would have on there asap
First off a reciever is not a motor controller. The receiver is what sends signals to the ESC. So you still need a motor controller.
You could use that battery to power the motors with a correct ESC or something else. The BEC would be used as a voltage regulator to power the receiver, if the ESC does not have one built in, and any other electronics considering they do not draw more amps than it can supply and run on 5v.
You want to go ask questions at this forum: http://forums.delphiforums.com/THERFL/? It is the Robot Fighting League’s home where all the builders post progress reports and ask their questions. There is also the RFL facebook page (https://www.facebook.com/BotLeague), but the forum will get you better answers.
