I’m thinking about building a robot just with some old parts I have.
The main thing is the motors. I have 2 DC Motors
Specs below. (It’s a MFA975D Series with gear ratio 49:1)
Operation range(Voltage): 12V
No load - Speed 147RPM
Nm = 1,8
The tracks of the robot will be caterpillar from old tires, driven by chains onto a gear.
My robot might gonna weight approx 40kg
How do i calculate of the motors are strong enough and what speed would I be travelling in? Only horizontal no degrees inclined.
EDIT Thanks for helping me with my issues guy, i appreciate it a lot! The 2 motors have to run in a controlled loop. So when I want to go forward both motors go forward, and same as backwards. When I wanna turn, the motors gonna work in opposite direction of each other.
The things I want to know is , could it be possible to even use that motor standard, or should it need to be gear lower, for more torque? And how I’m calculating the speed of a my machine with this motor, my weight, the friction (Rubber vs Asphalt).
