Larger Mecanum Rover – 3D Print Gallery
Posted by Madox in Perverse Applications of Science...
iPad in iPad view with TL-WR703N camera mounted
No actual write-up goes with this post other than a gallery full of photos for 3D printing enthusiasts. This was an exercise to demonstrate how large models can be printed using the Up! printer [Hah! if you buy use this affiliate code please!]. The hub of the wheels are about at the limit of the platform size of the printer but the body is constructed in a modular manner.
The rover itself is driven by 4 cheap continuous rotation servos like the original, interfaced with a cheap MSP430 Launchpad and controlled by a wireless Wii Nunchuk. The webcam in the photo above is connected to a TP-Link TL-WR703N which acts as an access point and streams to any WiFi device with a web browser (iPad above…not mine!).
Edit : Forgot to add Youtube test video as usual!

我是来自中国的一名学生….我制作了一个Mecanum Wheel mini cai….用89S52…舵机价格是1.5美金一个..但是我打印的Mecanum Wheel 很粗糙，你是用什么型号的3D打印机呢？
I am a student from China …. I made a mecanum Wheel mini cai …. 89S52 … Servo Price is $ 1.50 a Mecanum Wheel .. but I print very rough, you are usingWhat type of 3D printer?
Google translate
Which servo are you using that is so cheap? I am using the pp3dp Up! which is from Beijing
I used SG90 servo.It’s like this
https://www.google.com.hk/search?q=SG90&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:zh-CN:official&client=firefox-a
so，you are in china。now？
No but I’ve been to China many many times. The SG90 is a bit small for my liking, I’ve built smaller mecanum wheels using those 9g size servos too
Do you have url about this 9g size servos mecanum wheels ，I want to refer add to my car. SO, I Want to know You generally use instant messaging tools addition to MSN
I only have some photos I took when I was building them :-
