Made this attempt with Thumper today. Snow plow was a 3D printed part using Makerbot.
Thumper does not have the power or the traction even though I have 2 1500 watt batteries in parallel.
This is the flattest of 3 solar arrays, the others it would not work at all.
Any suggestions.
Use better tyres for more grip too, there's no point in increasing torque if you can't transfer the power from the motor to the surface you are driving on. Believe it or not, weight distribution can play a huge part in helping get the power down.
No the batteries are 1500 watts each in parallel. Panels are 225 Sharps. I have 43 on roofs.
I may try the tractor base I have.
It is snowing now here in NJ and I tried again and he slide almost off the roof.
Tried different setting with PWM.. no success... the biggest problem is the traction.
I need to be careful.. don't want to break the panels.
Throw some decent tyres on that thing and improve grip. Distribute the weight over the drive wheels to get the power to transfer from motor to surface. You could increase the torque but if it can't get the power down it'll sit there spinning it's wheels. If it already spins it's wheels start with weight distribution and tyres. If it doesn't then increase the torque with either better motors or more volts.
Rubber is soft because i place outside and start right away.
Is there a way to adjust the spring tension on the suspension?
If were flatter it may get more traction also.
