WEEK 31: EXHIBITION DAY

OBJECTIVE

1. To present my quadruped robot prototype on the Exhibition day.
2. To explain my project based on the presentation poster.

METHODOLOGY

1. Going to the UniKL BMI Gemilang Hall before 9 am on Wednesday, October 24th.
2. Register for presentation.
3. Set up the poster and quadruped robot prototype.
4. Present the project to the assessors with confident.

RESULT

The following pictures are taken on the final year project 2 Exhibition day. 

ANALYSIS/DISCUSSION

The presentation going well. There are no problem with the project. The quadruped robot works perfectly. The assessors are satisfied with the presentation. After presenting to the assessors, I do some explanation and demonstration to the other students that interested with my project. I finish assessed at 10 am. The Exhibition day ends at 12 afternoon.

CONCLUSION

In conclusion, both of the assessors which was Professor Dr. Badri and a research engineer from UNITEN was satisfied with my presentation. The quadruped robot works perfectly without any problem. Thus, the presentation was going as planned.

WEEK 30: DESIGN POSTER AND PRESENTATION PREPARATION

OBJECTIVE

1. To design a poster for presentation day.
2. To do final preparation before the Exhibition day.

METHODOLOGY

1. Design the poster using https://www.canva.com.
2. Meet supervisor to ask for advice on doing presentation poster.
3. Showing supervisor soft copy of poster before printing.
4. Updating the poster according to supervisor.
5. Print out the presentation poster.

RESULT

The presentation poster as figure below.

Presentation Poster

ANALYSIS/DISCUSSION

The poster is design using https://www.canva.com. The contents of the poster is written based on Sir Zaki wanted. After finishing the first copy of the poster, I consult Sir Zaki to as for his opinion on the poster. Then, he wanted me to do some correction. Hence, before print out the poster I consulted Sir Zaki again to see if there is any correction have to be made. The poster is print out after Sir Zaki is satisfied.

CONCLUSION

In conclusion, the presentation poster for the Exhibition day is print out. The quadruped robot prototype is fully charged and ready to present.

WEEK 29: PROTOTYPE TESTING AND TROUBLESHOOTING

OBJECTIVE

1. To test the prototype quadruped robot.
2. To troubleshoot the prototype quadruped robot.

METHODOLOGY

1. Test the robot WiFi access point connection to the smartphone and laptop.
2. Test the robot movement functionality.
3. Troubleshoot if there is any problem countered.

RESULT

The following video is a video of testing the robot movement functionality.

Prototype limb movement testing controlling using laptop

After connecting the Wemos D1 Mini WiFi access point using laptop. The ESP8266 IP address is open through internet browser. The address are '192.168.4.1'. The quadruped controller showed up for me to control the robot.

After that, I tested the robot to walk. Eventually, the robot's leg is very slippery thus i put some glue using hot glue gun to the point of the legs to reduce it's slippery. 

Hot glue gun is used to put some glue on the end of the legs to reduce the slippery problem

After finishing putting glue on each legs of the robot. The quadruped robot is tested again. The following video show the steps to control the robot using smartphone.

Quadruped Robot walk testing

CONCLUSION

In conclusion, the robot has achieve its fully functional capability. This prototype quadruped robot is completed.

WEEK 28: BUILD PROTOTYPE

OBJECTIVE

1. To assemble the electronic components.
2. To assemble the 3D printing body parts.
3. To build the quadruped robot prototype.

METHODOLOGY

1. Uploading the coding to Wemos D1 Mini and ARDUINO Pro Mini.
2. Assemble the Wemos D1 Mini, ARDUINO Pro Mini and PCA 9685.
3. Assemble the 3D printing body parts with servo motors.
4. Connecting the servo motors to the PCA 9685 according to the port declared in the coding.
5. Soldering the positive and negative of Li-Poly battery to the switch and DC-DC step down converter and UBEC voltage converter.
6. Connecting the DC-DC step down converter to the Wemos D1 Mini, ARDUINO Pro Mini and PCA 9685.
7. Connecting the UBEC voltage converter to all the servo motors.
8. Tighten the screw and glue the components to the robot to complete build the quadruped robot.

RESULT

As a result, the following pictures are the process of assembling the quadruped robot prototype.

Assembling each leg parts with two servo motors

Screwing four servo motors to the body part

Complete assemble of 3D printing body parts with Servo motors

Complete connection of the electronic components, Li-Poly battery and the robot body

ANALYSIS/DISCUSSION

The arduino and Wemos D1 Mini was uploaded with the coding before connecting to each other and other components to avoid error from the board. The servo horn has some difficulty put because of the 3D printing leg parts has small space to put the servo horn. Hence, the servo horn is tighten to the leg using cable tie. The body of the robot has small space, it can only fit with Wemos D1 Mini, ARDUINO Pro Mini and also PCA9685. The UBEC and DC-DC step down converter was place on top of the robot, glued along with the Li-Poly battery. 

CONCLUSION

As a conclusion, the quadruped robot prototype was finish assemble and the robot is ready to be test.
