If anyone is interested in selling their Maslow Kit please email me at firstname.lastname@example.org. We built it over the summer with the goal of having it ready for our Robotics Summer Camp. The challenge was finding a motor substitute. Used 100:1 planetary gears and was able to move the sled around with some degree of precision until the at rest problem became obvious. Then tried other worm gear options. Using worm gear from textrix got things moving again but appears we have a slipping problem going up and to the left not to mention different motor gearing ratios etc.
Would really like to get this project finished so the kids can use it. If you are interested in selling your kit will be happy to cover the original cost of the kit purchase.
