Previous Development

Previously, I assembled Ver.2.

Finally, color printing!

Now I will print a slightly modified version of the previous Ver. 2 (let’s call it Ver. 2.1) in color. So far, I have used Z-HIPS filament for Zortrax M200 Plus, but this time, I will use Z-ABS. (Figure 1)

Figure 1: Z-ABS, available in gray, yellow, and red

The printed version is shown in Figure 2.

Now, let’s start assembling. The basic parts are the same as Ver.2, but I have modified some minor parts. (Figures 3 and 4)

Servo motor is SG92R as before.

The impression changes when it is colored.

I paint decorative parts such as eyes and antennas. It was quite tedious, so it would be better to color this with a 3D printer…(Figure 5)

Now I can attach these to the head cover, and I completed the assembly of the main part. It looks good. (Figure 6)

Finally, a sensor using the US-100 ultrasonic distance-measuring sensor is mounted to complete! (Figure 7)

Let’s move it!

Now, let’s actually run it with a simple program. The robot performs a walking motion, and when it detects an obstacle with the ultrasonic distance sensor, it shakes its head and stops.

This program manages the US-100 ultrasonic distance sensor in the manner described in a previous article here.

There are still a few more things to be corrected, but it seems to be approximately complete!

Next

I will begin creating more complex motions and implementing detailed functions for movements in the next article.
