RE: Cat Detector Using Sand #3 : The Results

"...The use of tyres for an external mobile robot has problems due to slip caused by sand as well as wet surfaces so for future outdoors mobile robots I will have to have a think...."

That was quite impressive for wet sand.

Perhaps you could have a height adjustable grader blade so that when traction is about to be lost, the cut depth on the blade is reduced and the job completed with multiple passes ?

I guess that you could do similar with a spring loaded blade such that it starts to deflect before traction is lost.

A heaver battery would probably also help with traction.

Nice job! It is good to see that your system was able to survive the elements. Keep in mind that wet sand is a lot more difficult to move than dry sand, so some stall/slippage is to be expected. You might be able to roughen up the wood (add texture) to give your tires some to grip on. They make non-slip tapes to add to stairs and such that you might be able to apply to the upper edges of your sand box.

Keep up the good work!
