 | | Gearing down a lego motor
|
|
Hi, Before I invest a lot of time on this, what is the minimal gearing I need to do in order for a Lego motor to let itself up. How about a lego motor lifting itself and another motor up? I want the motor to be powerful but at the same time fast... (...) (24 years ago, 20-Jan-01, to lugnet.robotics.rcx, lugnet.robotics)

For the navigation of my robot, I do not plan to use float or trig function. I will use long integer (32bits). the high 16 bit are the true integer value. the low 16 bits are 1/65535 value. let say 1 = 0x00010000 2 = 0x00020000 2.5 = 0x00028000 2.25 (...)
