Ez-B V4 Wi-Fi Robot Controller

I am using the EZ-B v4 Wi-Fi Robot Controller to replace the receiver in my RC car and make it into a robot . The 7.2 V battery powers both the motor and is connected to the ESC which then plugs into the receiver and powers the receiver also . The other servo for steering is also powered by the connection of the ESC to the receiver . Can you tell me how I should hook this up to my EZ-B v4 Wi-Fi Robot Controller . Also is the 7.2 Battery in the car OK to power everything or should the EZ-B v4 Wi-Fi Robot Controller have its own 7.4 Lipo power source .

Yes, the 7.2v battery is fine for the ez-b v4.

There was a little bit of direction in your first thread here: https://synthiam.com/Community/Questions/8338

In that other thread, the answer to your question is to connect the servos and ESC directly into the EZ-B. Use the Modified servo Movement Panel and that will replace the ESC.

The biggest challenge will be adjusting speed and steering. Robots are usually much different than cars - so there is really no control that will plug and play for your steering need. I'm sure we can all work on something to help you get it though:)

Thank you very much . I just did not want to hurt the EZ-B v4 buy pluging the powered ESC into it . I also noticed most robots work like tanks with four motors and use them for steering . This will be a big challenge, but if we can solve this steering problem it will get a lot of RC guys I know to buy the EZ-B v4 and turn a lot of RC cars into fun robots . My rock crawler moves very slow so I think the motor control can just be one speed forward and one backward . The steering is the big one . I'll be back and thanks again , I knew EZ Robot was the way to go with this project.

I was going to use your Ultrasonic Distance Sensor To make the car turn when it encounter an object . That way it can just activate the steering servo left of right , correct ?

You sure can - that will be pretty easy.

The steering will be a servo, correct? So all you need to do is move the servo position to move the wheels.:)

Just one more thing , I want to double check and make sure the power going to the ESC servo plug that I plug int the EZ Bv4 control board will not hurt the EZb v4 any since I will be powering the EZ bv4 directly form the 7.4 battery also . Please advise ?

I am sort of doing the same thing now, finally hooked the servo up to the steering. I was curious with the custom movement panel, i can make the wheels go right then go forward/reverse, and same with left. But how would i go about making the wheels return to the straight position. I tried having the wheels go straight during the stop position, but then i wouldn't be able to actually move forwards or backwards while turning.

If you use the custom movement panel, for every direction you can set a servo position. As for turning while moving forward, you can make a custom Movement Panel with extra buttons with the mobile interface builder.

@sadi heric No, you need to remove the power plugs from the connector. Just the red. Leave the ground and signal.
