This project guides you through building a robot that can wander around your floor. This riffs on John Park's Crickit Carnival Bumper Bot. The difference is that the project progresses through several levels, starting with a very basic bot and adding capabilities.
Parts
Basic Design
You won't need the battery holders if you decide at the end to use a LiPo battery.
1 x
Circuit Playground Express
ATSAMD21 based educational board, that's loaded with I/O devices and CircuitPython capable.
2 x
Orange and Clear TT Motor Wheel
Wheels for the TT motor. This is one of the available options which provides good traction.
1 x
3xAA battery holder
Use this if you want to use Alkaline batteries. This is one 3xAA holder. there are others and depending on which you have you may also need the DC Power adapter. This wasn't available at the time this build was done so a different holder was used.
1 x
Male DC Power adapter
2.1mm plug to screw terminal block, if your chosen battery pack doesn't have a 2.1mm plug.
1 x
5v power supply
Handy power supply to have while working on a CRICKIT project at your desk, or to power a stationary project.
1 x
Cardboard Pop Rivets
Small plastic rivets that are great for joining pieces of cardboard ot other thin things. We'll use them to connect body segments.
1 x
20 6" F/M Jumper wires
Great to have around, and used here to connect the micro switches to the CRICKIT
A bigger, better power system
If you do this, you'll also need the power adapter and a F/M jumper wire listed above.
1 x
PowerBoost 1A LiPo recharger and boost
For charging the big LiPo as well as boosting its 3.7v to 5v to power the CircuitPlayground Express and CRICKIT.
