2WD robot platform for FPV with Sabertooth 2x25

[@hitsplayradio]

Hello, how did you fix the wheel with the crown ? please do you have a picture ? regards Emmanuel

[@Zaettn]

Hi @Epic Stuff Maker , what diameter does the axle have? is it an 20 mm? I am on building something similar and its hard to find a mount for a sprocket fitting to a 20 mm axle (which fits to wheelbarrow wheels). thanks

[@epicstuffmaker]

The axle diameter is 10mm. I used a 3D printer to print a spacer so that the sprocket could be fitted. So if you have access to a 3D printer you could try to print what you need, otherwise you will have to visit all the hardware stores in you area to find the right parts (like I do the most of the time).

[@senahaloka]

Today I went local market to get wheel but didn't get so pls guide which wheels easy to buy in online amozon or eBay

[@epicstuffmaker]

I used two spare wheelbarrow wheels. It can also be found on ebay.

[@fuzywuzy2541]

how did you program the ,,,controller to operate the motors? to me thats the hardest part overall, except the build of course,,its very cool,,,and the best presented on youtube

[@epicstuffmaker]

I used the Sabertooth 2x25 motor controller. no programming needed here. just connect and drive :)

[@fuzywuzy2541]

what i mean is ehm? how do you get the controller to move the motors.. i mean for example (right motor backwards) + left motors forwards.........have u got a link as to how you configured youre (controller) to.....move the motors back and forward....brilliant video and its so clearly presented with great picture well done man.

@@epicstuffmaker Thanks. Here is the gospel- When you die you are going to stand before God and give an account for your life. Because God is good, He is going to judge you according to the perfect moral standard of His law. If you have ever lied, stolen,taken His name in vain, or sinned in any other way he will find you guilty of breaking His law. Because God is good he must punish your sin;the punishment for sin against God is an eternity in Hell. While God is righteous and just. He is also merciful,loving and kind in that He provided one way to escape that punishment and that was through the gift of His Son Jesus Christ. Jesus Christ fully God and fully man without sin. He died on the cross a death He did not deserve taking upon Himself the punishment you rightly deserve for your sins against God Three days later Jesus forever defeated sin and death when He rose from the grave and he is alive today. What God requires of you is that you repent (turn from your sin and turn toward God) & by faith alone receive Jesus Christ as your Lord and Savior. Repent and believe the gospel while God has given you time

[@roboticsandnanotech3051]

how you made that work to rotate the shaft in different direction

[@epicstuffmaker]

Shaft doen't rotate. Chains drive the wheel directly

[@roboticsandnanotech3051]

@@epicstuffmaker no what I mean is how u connect the two wheel which rotates in different direction via a shaft

[@epicstuffmaker]

@@roboticsandnanotech3051 wheel has a bearing inside

[@roboticsandnanotech3051]

can u please send the link for the wheel

[@roboticsandnanotech3051]

and sorry for the disturbance, I am doing this as a project and thanks for u r model and idea.

[@tomdarcy1064]

Can we obtain a complete parts list and some suppliers. I need to build one for a disabled person to go to the beach on loose sand. The cart looks great. I have no idea what I am doing. I am a beginner. Thank You for your help.

[@robertb4396]

Is the rear axle ( rod ) cut in three parts ? How , does the little smart bot manage to turn with one axle instead? :)

[@epicstuffmaker]

The rod is in one piece. The wheel's rim has a bearing that runs on the rod.

[@robertb4396]

Cool! The free bearing and the motor do the magic . Thanks.

[@MrCoder101]

This is called a dead axle set up. Axle is stationary. Wheels rotates on it.

[@alessandrodionisivm]

Hello, in which language did you control the sabertooth? In particular what PWM frequency are you using? I'm trying with 100Hz but motors emits a lot of noise, I'm not sure it is correct. Thanks

[@epicstuffmaker]

Alessandro Dionisi, RC receiver is dirrectly connected to the sabertooth. No programming needed.

[@chloecamtole2957]

Radio & Receiver frequency best at 2.4ghz.

[@alessandrodionisivm]

Can you tell me the model of your motors and driver? Nice project!

[@epicstuffmaker]

Motors are from electric scooter and the driver is the Sabertooth 2x25

[@alessandrodionisivm]

Can you gently give me motor specs?

[@epicstuffmaker]

Can you tell me battery specs? Is that a VRLA battery? How much does it last? Thanks

[@OilBaron100]

Where did you purchase the wheels from? What about the motors?

[@epicstuffmaker]

Wheels are from local hardware store, electric scooter motors are from ebay

[@OilBaron100]

I've never seen those kind of wheels in a hardware store. I live in Australia. What is the intended purpose that they are sold for (ie: are they sole as wheel-barrow wheels, bicycle wheels, etc)?

[@epicstuffmaker]

yes, they are wheel-barrow wheels or cargo cart wheels :)

[@OilBaron100]

Did the wheels come with the sprockets attached? Or did you attach them yourself? How do they attach to the wheels? Where did you buy the sprockets from?

[@epicstuffmaker]

OilBaron100 sprockets are from a electric scooter. I used my 3d printer to make an interface between the sprocket and the wheel.

[@cuylerwilkinson4414]

how many teeth do the rear sprockets have?

[@epicstuffmaker]

I think its 55
