WalkBot (Basic Version)

Our project is to create a friendly walking robot that moves with the help of motors and on a battery. we 3D printing tiny legs and body parts, just like building blocks for our new robotic friend. We'll connect them with wires & switch.

checkout & follow below step to make WalkBot.

Materials:

• BO DC Motors (quantity as per design)
• 9V Battery
• 3D Printer Filament
• 3D Printer
• Switch
• Jumper Wires
• Screws and Nuts

Tools:

• Screwdriver
• Soldering Iron
• Wire Cutter
• 3D Printer

Use a Fusion360 software to design legs and body parts. Ensure that the parts are hollow to accommodate the motors and wiring.

1. accommodate 2 BO motors side by side and make enclosure.
2. Consider Shaft of motors comes out side.
3. use holes to constrain motor or we use Glue gun for that.
4. make a Legs of WalkBot .
5. add pivot point of robot .
6. add legs and motor connector.
7. add thickness of parts 2mm.
8. After completion of design, Export each part as .STL file for 3d printing.

Before do 3D printing we need to Slice STL file to make GCODE files.

I use CURA for Slicing.

I attach .STL files for casing and legs below.

Parameters.

• Layer thickness=0.2 mm
• wall= 2
• top/bottom=3
• Infill=30 %
• Material = PLA
• Speed =45mm/s
• Support = no.

Use above parameters for good 3d print.

Attach Motors: Secure the BO DC motors to the 3D printed legs using screws and nuts. Ensure they are securely attached to provide stability.

Connect Body Parts: Assemble the 3D printed body parts, leaving space for the battery and switch. Use screws to connect the parts securely.

Wire Motors: Connect the motors to the battery using jumper wires. If necessary, use a motor driver to control the motor speed and direction.

Add Switch: Integrate the switch into the design, ensuring it is easily accessible. Connect it to the battery to control the power supply.

Connect Motors to Switch: Use jumper wires to connect the motors and the switch. Ensure proper polarity to avoid damage.

Connect Battery: Connect the 9V battery to the switch and motors. Double-check the connections to avoid any short circuits.

Power Up: Turn on the switch and observe the movement of the walking bot. Make any necessary adjustments to the motor connections or body parts.

Fine-Tune: Adjust the walking bot's design, weight distribution, or leg movements for optimal performance.

Secure Components: Once satisfied with the performance, secure all components in place using additional screws or adhesives.
