Started work on redneck rollercoaster

Started work on redneck rollercoaster

Been very busy with different things the past few weeks but have been able to work on this. the idea is that you drive forward and then slam on the brakes and the whole robot tip forward, the person almost hitting the ground, then it pops right back. my problem has been getting a good balance. This is also my first 4×4 vehicle so i can stop the front wheels to make it tip but sometimes that’s not enough so it has to be put into reverse quickly but sometimes that makes it tip forward too much and get stuck. So, basically, it needs work.

Forklift testing

I’m back from vacation for good now and have finished my prototype of a forklift that uses no string, linear actuators, pneumatics or rack gears. It works pretty well. Ultimately I will have a  polished program and instructions but I first have to modify it for NXT 2.0 only (I think all I have to do is change the gears and the back wheel). Podcast with final version and instructions should be out by the end of the week.
