I’ve made a list of parts and a budget estimate according to them to build an OpenRC truggy with an Arduino as the brain, is this list complete or am I forgetting something?:
-Carson Body
-Arduino Uno + Arduino Motorshield + BLE (Bliuetooth) Shield
-9V Battery
-7 AA batteries,
-Universal battery charger
-LED lights, front + back + blinkers + braking light + bluetooth check
-Transistors + resistors + switch
-Tires/wheels
-Drive servo (Blue Bird) + steering servo (Blue Bird)
-Glue/paintset
-Shock absorbers
-Bearings
-Bolts/nuts
And that should be it, plus I calculated 24,69 euro for unforeseen costs.
What do you guys think? Is my list complete or am I definitely missing something important? Wouldn’t want my project to fail because of budgetary problems, so I should get the budget straight before I start. Thanks in advance!
Most people buy CVDs as well. I also got wheel adapters because they were cheap. Are you planning on using the bluetooth to drive it? Also, are you planning a servo motor for the drive and not a brushless cd motor. Most of us have brushless DC motors and a motor controller for the drive. Are you going to use the 7AA batteries to run it? Most of us use a rechargeable battery pack so that we can get enough power to run the dc motor fast. I suppose it all depends on what do you want to do with the project.
@Renier_Wijnen Yeah the CVDs can be cheap and in my opinion it would be a waste of time to make your own.
When you say servo motor are you talking about a dc servo motor, or a hobby servo that has been modified for continuous rotation? Brushless motors are much more powerful than a hobby servo. For small things that will move slowly a hobby servo works, and I know that you can control the speed very easily.
The other one is a servo motor which is a dc motor with an encoder built into it. To be honest a brushless motor and motor controller for RC cars is basically the same. But it doesn’t have an encoder built in and I believe they are an open loop control system.
I look forward to seeing what you build. Keep posting as you build it.
Here you can see two videos showing the OpenRC truggy with a brushless motor speed and another video that shows a robot using hobby servos modified to have continuous rotation.
Personally, I like the fast option. But it all depends on what you want to do with the car when its done.
