Here's my try to make a low cost, portable, educational, robot:)
Dagu Mini driver+HC05 + other sensors.
Scatolot was born from my need to bring on my backback a little robot show when i go around, just to prove that how awesome are robots, and something easy to thinker with when i'm bored. So low weight and space^^
The body it's just a plastic box with lot's of holes to mount electronics and motors.
The box it's really nice because it can contain almost all electronics, decent dust and spash protection, and easy to open to add things.
But the space inside it's quite tight so i couldn't fit in an arduino and the motor shield.
The dagu mini driver and the bluetooth chip HC05 are small enough.
The robot can already move, but i haven't finished the code yet.
I plan to add a solar panel, a way to recharge it trough USB and a ultrasonic sensor.
No luck with the hc05, and dagu mini driver, i'll add a hc-sr04 and call it autonomous:)
Next version i will try use arduino mini+shield and l9110 driver board(more available).
Right now it's funny enough and collects dust from the floor.
The solar panel isn't linked yet to the battery pack
Added the HC-SR04!
Added new video of it moving and avoiding feet.
Added BasWheels with aggressive spikes as wheels!
The BasWheels don't act as suspension as i would expect(hard PLA), but it bestows the Scatolot better traction over grass(tried on wet grass), where the small yellow wheels were failing miserably.
The wheels are very disappointing on flat smooth surface, almost no traction.
