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

 

Components:

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

Instructions:

Glue both parts, the base and the frontal face.

Glue the FS90R servos to the base, the servo axis has to be as far as possible to the frontal face and screw the wheels to the servos.

Glue the caster wheel to the base

Glue the TCRT5000 support just below at the feet and glue the TCRT5000 sensor to the support (glue it so the sensor is below the feet horizontally).

FS90R servo cables and TCRT5000 cables can be now pass through the base hole. After that, we can glue the LEDs matrix to the frontal face (cables pointing downwards).

Glue the ultrasonic sensor HC-SR04

Now, glue the SG90 servos, with the axis pointing downwards. The servos are located at their corresponding holes at the base. The servo horn must be screwed to the servo axis so that the minimum position is pointing to the legs (to avoid collision).

Glue the LEGO parts to the servo horn

 

Finally, glue the Arduino electronics, Powerbank, buzzer and Bluetooth module to the robot base.
