Make a table-top mini-wheeliepad #1298

Open goatchurchprime opened 4 years ago

goatchurchprime commented 4 years ago

There are a lot of designs for self-balancing Rpi robots, like here: https://3dprint.com/16435/3d-printed-raspberry-pi-robot/

@MatthewCroughan thinks it's easy to bolt on a webrtc screen and mic and camera on the front, which would mean we could be running a table-top, head height (for those sitting) telepresence robot to run freely across the board-room executive table.

Alternatively, one could use the gyros in an android tablet and send the signals and control inputs by bluetooth to an ESP32 motor controller.

Some of the precedents I was discussing with you in person.

We've got a drawer full of these, which does 2A and up to 15V for driving DC motors using a PWM over an H-bridge: http://wiki.seeedstudio.com/Motor_Shield_V2.0/

We can either use the old fashioned form-factor of the arduino, which would fit the board, or retrofit from something from something that can make a good PWM (ie not an ESP). Maybe @cheapjack with his new 555 timers could do the job of converting from an analog signal to a PWM duty cycle.
