Time to get the printers warmed up!!

In this tutorial I will show you how to assemble the back covers. It is pretty easy if your prints are correctly printed without warping otherwise, you will have a hard time to join all the parts together.

Some of these parts require support during 3D printing, so please check the bellow list.

Here is the list of parts and the number of prints needed for the back:

Step1:

Trim all the support off your prints and make them all clean!

If you plan to use extra servos for the neck (Bob Houston upgrade) You will need to rotate upside down your Arduino and Nervo boards, mainly because the USB cable is not well positionned.

If you don’t plan to use the servo upgrade, you can start by adding and gluing all the holders to the torso plates.

You might want to check the 3D sketchs to see what part goes where!

These small parts should be glued. Nota: the files you have printed will look different because I updated them to allow the set up for extra neck servos.

InMoov back holder Mid

The middle should also be glued. If your parts are printed in ABS, you can use acetone.

Same thing here for the low holder, Use glue or Acetone

You need to add screws to fix the center holders. But it also can be glued.

Step 2:

It is better to assemble the parts directly on site to avoid deformations during the time it dries out. Use some clamps to glue and hold the parts together, this will seriously help to make proper fittings.

You have the option to add 2 switchs on each side of the robot for various purposes. I use one as main shut down., another one is to power up the mini Amplifier. The third is to power up the wheel mobile base and the fourth is currently vacant. These switchs are available in most spare electrical stores and on internet of course.

If you had already printed the Battery holders of the previous version, you can saw them or re print my new version. The new version of Battery Holders allows you to add a copper sheet on the top where the battery slides. Therefore when pushing the battery into the back, it can automatically give the power without having to connect wires everytime you switch battery.

image(9)I fixed my USB hub on the bottom of the back. You can see it is a 8 port HUB USB3.0. on the right side (blue) it is my USB Soundcard. On the top left, hanging,(in red) there is the audio jack that goes from the mini Amplifier to the USB Soundcard.

IMG_1997Connect the mini USB OTG cable to your Thinkpad Lenovo 8″ Tablet (see BOM for part list) and place and press fit on the back of your InMoov.

You might notice that there is no gap to connect the audio output, the reason is because I’m using a USB soundcard 3.0 which allows me to send the audio to the mini Amplifier. The USB soundcard also has an microphone input, which is handy in some environments. So all sound is treated through USB.

At this date 06/06/2016, I still need to make some modifications on the battery door before releasing…

Check for the Upload & Update page in the gallery.

Have fun and be kind to your InMoov!!

      As described in the Hardware and BOM page, you need a USB OTG cable which can also supply power to the tablet and also connect a USB Hub.
      All USB devices (Arduino, Kinect camera, headphones..) are connected to the prescribed Hub 3.0. To be autonomous you will also need an extra powerbank (10000mAh) and a a power supply for your hub which can deliver at least 4Amps.
      Remember each USB devices consumption is about 500mAh. If your Hub doesn’t get enough power, the USB will disconnect and reboot all the time.

    Hi Gael!!!!!

    Congratulation, is amazing… im bulding the second inmoov but i have a questions, can you recomend alternatives to the Tablet, now i have problems to buy that, and need recomendation to big servos, any recomendation to buy anothers more cheap if not I will have to save to buy the recommended. and finish THE LEGS, i can not wait… its a joke, jajaja thanks gael and receive my congratulations

      I haven’t found a replacement tablet yet…
      If you find one, let me know, it will be helpfull for others as well.
      For other servos, I recommand you look at the “Hardware and BOM” page where I listed other possible servos.
