I have decided to build a single wheeled bot and im keeping it simple, since this is my 1st build. No arms, no servos(other than for the wheel), and no body covers. So, it will be no wider than the ez-b board and no taller than a tire, servo, board, gyros, and battery pack. I'm going to use two futaba gy401 gyros, one I have already purchased. My issue is this: I'm unsure of how I will attach the gyros to the server and then to the board. I have a design in mind, but I'm not sure how to design the wiring. Any help is appreciated.
Oh, and I want to control the bot with a wimote.
Thanks
Oh and if you want left right twist you could get and extra two servos but that. Axis is already balanced so it doesn't need a gyro. Im going to draw out how this plugs up. The reason why you need a h bridge is because the gyro connects directly to h bridge and will feed it signals to stay level. This does not require programming only adjustment of the gyro trim and sensitivity and you let it do its job. Then when ezb feeds it a signals the robot moves in that direction portional to the input signal to the gyro. Rc gyros are setup to be inline. Because the rc servos can be used straight up as a geared motor by removing their controller and soldering leads. This insures they arent drawing power from ezb and the h bridge and feed the servo power it needs to adjust quickly. Also I would run the servos at 6v
I have one h bridge.
So, I need to order two more servos and one more h bridge
Ok, I'm following...so far.
Twist or strafe would be kind of cool.
Twisting? You ask and you shall recieve!Diagram make sense?
Yea, it does. So to be clear, I only need one h bridge, correct?
I can use any port on the h bridge I want as long as I tell the software which one I'm using, correct?
Where on the h bridge will the gyros hook into?
Is there a particular online store you use for structural components?
Ill update the drawing. Yes 2 h bridges and if you want side to side twist you need to pick up two for that side to side motion. If you dont want side to side twist you wont need the second h bridge. Ok so heres parts list so far assuming you do the twist..
Ezb 6 cont servos (2 you already have) 2 l298n h bridge 2S lipo battery Ball caster ( for center load) 2 futuba rc gyros 6 servo spline tires ( you can use ones that come with ez robot cont servos but there are omniwheels that will allow twisting action smoother i believe) A ball, mini basketball works great at around 20 psi Servo ext cables , about 20 should do
