Hi everyone!
New member with a request for assistance from those far more learned in robotics than I and my 12yr old daughter.
She entered science fair recently and wanted to do a simple robot. Well, long story short I’m up against the wall with time - this thing needs to be handed on March 4th.
This robot is very simple. We simply need it to move forward and backward, turn around, plus raise a lower a scoop in the front of the unit. She will navigate it around the floor, scoop up a cotton ball or something else small and light, and deposit it in a cup.
Simple, one-time use deal. I highly doubt this will ever be used for anything again - so I need it to be as cheap as possible to build.
In doing her research she figured that she needs:
]2 servos (continuous?) for the wheels/:m]
]1 servo (rotational?) for the scoop arm/:m]
]2 large wheels plus 2 swivel wheels in the front and back of the unit for stabilization/:m]
]1 receiver /:m]
]1 controller – I saw one that wired directly to the device which I’m guessing would eliminate the need for the receiver./:m]
]1 battery/:m]
]/:m]
Is this the correct list of parts we would need for this type of project? Is there anything we’re missing? I’m sure there has to be at least a few things we’ve forgotten.
Additionally the battery MAY not be needed, since she would like to make it lemon powered. She found a tutorial somewhere that helps describe this process and give a rough estimate of the number of lemnos nedeed to produce the power for the unit. We are willing to forgoe this option in the interests of time and simplifying the project…but if we can include it this would be a plus.
I’m seeking any and all advice on this project. Unfortunately we are very pressed for time, so I will need to purchase the parts tomorrow to get them to us in NJ fast enough.
I went through the store on robotshop.com and came up with the parts listed below. It does NOT include the battery, connectors for the wheels or wires, scoop arm, etc. So I’ll need help there as well.

We’re desperate and will take any help we can get.
Thank you. I will monitor the forum for replies and private messages, but you can also email me directly at [email protected]
I really appreciate your help.
