I'm sorry for that mistake in the NEC H-bridge circuit the upper & lower transistors were reversed ,i hope that this one is correct
please tell me if there is any thing wrong with this circuit & how to overcome it?
to clarify :
I want your help to find the simplest h-bridge design that would do the job . no (PWM) no
(differential Steering)
I'm using this R/c transmitter & reciever circuits to control a small robot i made.
For throttle i'm using A (Mabuchi Motor) & for steering i'm using a small (powerfull) old
recorder DC motor both motors are geared.
it's a 2WD robot (2 wheels at the back 11cm radius) connected to a gearbox thorough (4 Rods & 8 joints)
& for steering (2 free wheels 11cm radius) connected together by (2 Rods 4 joints) & to the steering motor (a real car steering type)
the reason i built this robot is to simulate a real car or truck mechanism .
as shown in the provided picture there 4 shocks & the movement is transferd to the back wheels
through 2 axles so if there are small rocks in the way these shocks works great providing
A travel Radius up to 6cm (rear shocks) 4cm (front shocks)
note: the old h-bridge transistors data sheets S8550,s8050 & s9014 are included
i hope this could help!
i'm sorry but i have so many things in mind with regard to this topic ,is it possible to
use the s8550 & s8050 to drive the (NEC) D401 & B546 H-bridge
