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.

Supplies

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

Step 1: Design in Fusion360

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.

Step 2: 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.

Step 3: Assembly

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.

Step 4: Electrical Connections

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.

Step 5: Testing & Finalization

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.
