Mobile Robotics Platform (Mark I)

Last crawled date: 4 years, 3 months ago

In the air - the sea - or on the land, the mission is to design an affordable platform ($6 -10) onto which we might print + push-on a host of programmable components.
Destined for use in our classroom, this first incarnation (Mark I) be for the land. We've plans a-printing for an ESP-32, Pi-Zero, 40/24Mhz analog, as well as bewired learning experience for our students.
Designed for classroom use on a student desktop, speed would interfere with the efforts of other students. (i.e. think "tank battle," rather than "road race" here =)
Since speed was not the need, we designed the Mark I to use a be-geared N20: Selling for between $2 - $5 on the 'bay, 6V - 9V is all we need to set things in motion. --We favored the latter.
The platforms is & shalt ever be designed to fit TIGHTLY together w/o using glue or screws... Feel free to grab a rubber mallet. as the spirit moves.
More to follow!
Notes:
(1) You'll probably want to epoxy the wheels to the motor shaft: Use one toothpick to apply the glue, then two others to rest the motor casing upon whilst drying.
Two popsicle sticks also balance the drying process well, if you've got them - see the photo for an example.
(2) Spacers also help when centering the back wheel into the back wheel holder.
Be sure to trial fit the pin into the back wheel before final assembly as seen - you will most likely need to ream-out some excess filament from around the wheel's hub-hole.
(3) Providing additional traction, the grooves on the wheels are also there to (optionally) let us add rubber-bands, string, or anything else that one might like to use to add even more grip.
