Assembly of DYOR DIY SpiderBot

In this entry, we show the assembly of DYOR DIY SpiderBot with TinkerCAD and make with laser cutting.

Components:

Arduino Nano + Shield Arduino Nano I/O (red)
Powerbank (yellow)
Ultrasound HC-SR04 (light gray)
Buzzer (black)
Servos SG90 ( blue) in the base
SmartCar motors (yellow)
SmartCar wheels (yellow/black)
Driver DRV8833 (black)
Bluetooth (gray)
Linetracker TCRT5000 (dark blue)
Caster wheel (white)
FS90R wheels (black)
LED Matrix (green)
LEGO parts (red)

Instructions:

Soldering

In order to assemble this robot, we will need to solder some pins. It is convenient to have all this prepared before assembly, so run the soldering steps first (after reading all assembly instructions).

DRV8833 motor driver requires some pins to be soldered, as shown in Figure:

Similarly, Arduino Nano v3.0 also requires pins soldering, as shown in Figure:

Finally, SmartCar motor comes without cables, but some terminal connector instead. We recommend to use DuPoint Cables to create proper cable connections. So cut on of the ends of the cables and peel it out and twist it around the motor terminal. To avoid soldering get damaged, we recommend to glue the cable, once is soldered.

Assembly

Glue both parts, the base and the frontal face.

Glue SmartCar motors to the base, with the axis as close as possible to the front. Fix the SmartCar wheels to the motor axis. Pass the motor cables through the hole in the base.
