Not surprisingly, the wires move whenever the motors flex, which they are designed to do. No special provision was made for protecting the wire insulation, which on my Wild Thumper was already showing signs of wear. Well the motor wires, all twelve of them, were routed through the holes on the chassis. I’m sure you’ve seen similar products, as this sort of chassis construction is used in many robot designs. The Dagu Wild Thumper chassis is constructed of aluminum channeling, which has several M3-sized holes drilled in it. The flaw is in how the wires were routed. These wires are, sadly, only 20 gauge, I was hoping they would be at least 18.īut that’s not the flaw. The six brushed DC motors each have two leads, the positive and negative power leads. I spotted the first issue almost immediately. The real issues came, however, when I examined the build. However, the wiring online was incorrect, as they wired the center wheel to the wrong motor group! No big deal in my case, as I wasn’t planning on using their wiring anyway, but it doesn’t say a lot for quality control. My kit was “prewired” with the motors going to a terminal strip. There was a one-page “instruction manual” provided with the chassis. They fitted on with a single Allen screw each, and the key was provided in the kit. The chassis came completely assembled, except for the wheels.
