Inem Robot

Navigate, head movement, controlled via android, camera to display image

inem's development start around January 2017.

Videos :

1. Robot control using Android

2. Android Interface control

3. First test is a bit fail (dark video , lack of light)

servo when attached is a bit noisy since I haven't add some capacitor to reduce noise.

Materials : galvalume metal, alumuniums, light metal sheets, acrylic

Electronic & Peripherals: arduino mega 2560, raspberry pi 3, h-bridge (l293d), 3 ultrasonic (planned to add 1 more above the camera on head and 1 more above the webcam at the arm (the 6 dof arm is developed separately)),head servo : 1mg995 and 1 mg996r, servo for arm : 2 jx pdi with stall torquee 20kg.cm @ 6v, 4 mg995 servo

Mechanic : simple mechanic, I just use differential drive.

this robot is pretty much inspired after seeing several good robot projects

thank you very much to give me so many inspirations...

not yet added some functionality just add some control over android since I just started to build this one around January 2017. Arduino source code: http://pastebin.com/hQpwv5Ka

I got a Monoprice Maker Select 3d printer about six months ago (first 3d printer), and I've made lots of robot parts with it. They can be had for around $300. I spent probably another $200 or so on upgrades, new hot end, a raspberry pi to run octopi on, and a few extra electronics. One of the things that has made a huge difference is getting it upgraded so that I can reliably print PETG parts, as opposed to PLA. PETG is a lot stronger. If you're really trying to get out cheap, the Monoprice Select Mini has a lot of really good reviews, and can be had for around $200. For research, the 3d printer subreddit is a great place to spend your time for a couple of weeks prior to buying your first 3d printer.

thank you for advice, I will check Monoprice, hopefully I can afford to buy one. My current budget to buy a 3d printer is only  $500 USD, probably I can buy a monoprice

Restricting yourself to a 3D printer which can print the entire body in a solid piece might not be the best option - consider splitting the body into multiple parts to allow you to purchase a smaller, better quality / better supported 3D printer. You would get the most "bang for your buck" by purchasing a kit.

Thank you for advice Mr Cbenson, I'm going to split the larger parts into smaller parts.

I will decide which 3d printer to buy within several weeks.

The inside looks like my working desk... But the robot is nice, I like messy robots, especially if they were made from scratch !

I'm curious how it will develop.
