First of all, congratulations to this masterpiece!
I was reading through the forum and I was curious about the small angular spike motor you are using in combination with a small linear actuator for front steering. How does this motor perform the steering with the (I guess) heavy weight of the machine. I read that the torque is not that high of the motor. Is your steering angle limited?
I am also building a heavy machine with linear actuator steering and I am curious if I can use the small spike as well, saves a lot of valuable space. Thanks in advance ;)
