I placed the tall robot on the Omni2000 base. I was told that if I put it backards, it would be more stable. Well, I did not try it the regular way, only backwards. It does not wobble at all. But, when I say forward, it creeps slowly. When I tell it go in reverse, it takes off like a ruptured duck, or because it is October next month, bat out of Hell. So, I am thinking about changing it back to original position so that it goes fast in the forward direction not reverse. I also put another IRON square from a second omnibot. So, it has twice the iron and three 12v batteries. It weighs a ton. Maybe it will work in the regular position. I also noticed that it does not do left and right correctly. on the right it goes Bump and moves about maybe an inch. On the left, it sort of turns left in a circle, not true left like 90 degrees as to what I expect. What do you guys think?
Thanks!
The comment you made sounds bad. If they are supposed to be equal then I am screwed. That means a problem in the base. BUT, why do they go Forward and Reverse fine?
I don't have the pwm setup yet, I am just going with the Left,Right,Forward,Reverse.
Thanks to both of you.
Thank You, my friend.
Have you tried the motors without them connected to the drivetrain? Do both motors work without problem in both forward and reverse with no load? Check this by applying 6-12v directly to the motor with no h-bridge, ez-b or anything attacked. It sounds like it could be an issue with the motors or the gearbox if it's jerky when moving, or possibly lack of power.
Incorrectly setting up the PWM (or not setting it up) shouldn't make it jerky when turning or slow when moving one direction but fast when moving the other direction.
I'd check the motors first, then check the drivetrain, then start looking at the H-Bridge and software, it's unlikely to be the software or H-Bridge from what I can gather.
I love this forum.
