#COVIDFREE Progress Report

By: Joe Lam

So today we have managed to make and attached our planned robotic arm onto the platform that would be our remote-control car. The robotic hand is used to grab and hold the hand sanitizer. It was now capable...

#ALPHABOARD - Testing the Skateboard

#ALPHABOARD – Testing the Skateboard

Today we tested the electric skateboard outside on the basketball court. We realized the motor couldn't handle the weight of a human being on the skateboard. Although, if there is no one on the skateboard,...

#ALPHABOARD - Assembling The Board

#ALPHABOARD – Assembling The Board

Today, we attached the velcro to the skateboard to hold the materials in place. After testing the skateboard, we ran into another problem. We found out that the belt for the motor is too big. To combat...

Arduino code for dc motors.

APS Post #11

I finally figured out how to change the direction of the motors. You change the HIGH and LOW. These are the changes I made: case Mid_button: digitalWrite(left_motor1,LOW); digitalWrite(left_motor2,HIGH); digitalWrite(right_motor1,LOW); digitalWrite(right_motor2,HIGH); break; case...

An ir remote sensor attached to 4 yellow wires.

APS Post #10

I finally figured out how to make the circuit work with the ir remote controller. It originally didn't work because I soldered it wrong, I wired it incorrectly, etc. If you solder the wires together, make...

#ALPHABOARD - Drilling and Designing

#ALPHABOARD – Drilling and Designing

Today we are drilling the hole in the truck to secure the motor in place. We are also still designing our container to hold all the parts onto the board. We drilled the holes in the truck and have attached...

#ALPHABOARD - Assembling The Pieces

#ALPHABOARD – Assembling The Pieces

Today we are reassembling the truck to put back onto the skateboard. We also fixed the issue with the wheel and gear. We are also brainstorming ideas on how we should attach the materials onto the board...

#ALPHABOARD - It Works!

#ALPHABOARD – It Works!

Today we put the motor, the ESC, and the battery all together! It worked! We also had to trim parts off the wheel, working further on what we did last post. https://www.youtube.com/watch?v=TIOk-vAlmHk We...

Pieces of styrofoam, 4 circles, 4 big rectangles, 2 small rectangles

APS Post #8

I started to cut the pieces of Styrofoam for the frame and wheels of the vehicle. I used a foam cutter, which melts the foam so that I can cut it easily. If you use one, you should probably wear gloves...

#ALPHABOARD - Received Our Materials

#ALPHABOARD – Received Our Materials

Today we received our battery, wheels, and battery adapter. The wheels that we ordered have holes in them, so we can fit the sprocket into the wheels now. We are working on putting the wheels onto the...

2 dc motors attached to the arduino.

APS Post #7

Today, I attempted to try a different DC motor, with a rotating "metal stick" instead of the spiky "propellers" from last time. I think I will use this from now on because it works better as an axle for...

4 AA batteries attached to the arduino by soldered wires.

APS Post #6

I successfully used 4 AA batteries to power the motors by soldering the wires together. I'll probably need more batteries in the future, but at least I know it's possible. Soldered wires.
