Hi All,
I'm in the planning stages of a new robot base. My last robot used servos for the drive wheels. This time, I want to use H-bridge motor control. I want this robot to be very maneuverable and capable of a wide range of speeds from a slow smooth crawl up to a maximum speed of 3 ft per second.
I had hoped to use 2.5 inch drive wheels but doing the math I would need a motor output speed of 275 rpm (loaded) for the desired robot max speed which I'm not even sure if such a motor or gearbox is available, system voltage is
7.2V nominal. I wish to keep it a fairly small tabletop sized base so nothing huge.I would also like the motor to have enough torque to accelerate the robot from a dead stop to full speed in a couple of seconds at the most.
I would appreciate suggestions and or specific part numbers for motors and or gearboxes or weblinks also. Most of the gearbox motors available on many of the robot websites are far too slow and many don't have even have the torque of a bottom end servo. Thanks.
