My Idea is to create a handcart which is driven by one or two electrical motors. I saw once on a hike at may that someone had used a old gras cutter motor to drive a handcart. This is how I started to create the idea.
This projects aims to be a open source do-it-yourself project for getting first experiences with motor inverters, different loads and speeds.
My concept is to start with basics to just drive the motors controlled by a arduino (ESP32) or raspberry/banana Pi.
The battery will be a lead battery because it is cheap or a LithiumIon Battery because it is light weight.
After finishing the first basic build, my plans are to continue to integrate a W-Lan connection for Information display on the smartphone. Also I would like to start working in recuperation for charging the battery up in downhill sections, but till now I have no experience in this field.
- a ultra sonic sensor could check the front to make sure the way is free to drive, if they detect an object the motor control will stop.
- Temperature, maximum Speed and power managment should be controlled from the system
- a control if the operator (user) holds the handle could be implementent on the ESP32 with a Touch-Sensor on the handle
I'm open for additional thoughts and ideas to make it a useful help to transport stuff.
Probably the best result would be if I could receive two TAPAS boards so I can drive the left and right wheel individually. Then there is the posibillity to make turns using the motor control.
this idea will get two TAPAS dev kits
