Complications with Robot

So… As the subject stated, I’m having… complications with my Robot. I’m very confused…
So… I was using my robot (Stacker Robot) with the Spektrum DX5e radio system. So while I was using it, my robot stopped working. My radio was still on. And curiously, my gripper was stilled gripped, like it wasn’t relaxed as usual.
I did figure out that my Rudder port (I’m gonna call it a port because I have no idea what else to call it at the moment if it’s not called a port) is constantly on. Like no radio needed. I plugged in one of my wheels and it started rotating. Didn’t even turn on my radio. Also, the arm of my robot, which normally when my robot’s off, rests up in the air, is now pretty much on the ground.

The battery is 6 volts (seems like it could be good information) and has to be plugged in to have the rudder be constantly on.

If I turn on my radio, my robot doesn’t function. I tried to see if I could re-bind the system (I couldn’t) but that didn’t work obviously. I don’t get it. Any ideas on what’s up?

Was it working before? If so, then that’s quite odd. It sounds like that channel is connected to a switch rather than a knob or joystick.
Suggest yanking all of the servos from the receiver, checking the battery level in the controller (ensure they’re all nicely charged), and then testing each servo one at a time on the same channel when connected to the receiver.
This will ensure that each servo works, and then you can plug them each back individually, testing as you go.

It was working before. My batteries are fine. My radio turns on. I did notice that my receiver does not, that’s where I think the problem is. Would I have to buy an new radio control and receiver for that?

Ideally not - it’s rare that a radio system stops working, but if you tried to bind it and it didn’t work, then you might have some issues.
You’ll need to follow the binding procedure again, just in case. Note that most come with a binding jumper.

I can’t get my transmitter to turn on to bind. Full battery and all. It’s decided to be stubborn.

The transmitter itself won’t turn on? It’s incredibly rare that that happens… hard to troubleshoot.
When you say “full battery” - are you using a LiPo?

No, I’m using a NiMh battery.

To confirm, the battery is plugged in, and when you flip the on/off switch, nothing happens?
If this is the case, and it’s still under warranty, contact the place of purchase and have them exchange the unit.
Did you check the battery’s voltage using a multimeter?
Last, is there a chance you plugged the connector from battery to the remote and got the polarity reversed?

Ugh. Sorry, I meant my receiver isn’t working. I’ve been drifting everywhere lately and didn’t catch the mistake. My transmitter works fine.

It’s rare that a receiver fails - we can think of only two reasons:

  1. Tried to power it using two different sources (which you alluded to)
  2. It needs binding (did you make sure to use the binding connector?)

If you opt for a new receiver, it will also need binding.

I have only one battery and I did bind it. Not sure why it decided to stop while I was using it…
I did use the binding connector.

Disconnect everything from the receiver, connect its normal power battery (AA most likely) and one servo to channel one. Does that work?

Nope. It won’t turn on.

Sorry to jump in but the receiver will not emit any light when powered, only if it’s correctly bind to the transmitter and the transmitter is powered.
Have you tried the binding procedure ?

It won’t power on to bind. Like, every time I attempt bind, my receiver refuses to power on. There’s no light.

Can you post picture of your Receiver in “bind” mode ?
