CSI Open Lab : Rover Challenge

The Chabot science center holds hands-on activities for kids. This weekend the challenge was to build the tallest and/or heaviest and/or fastest Rover with Legos, motors and solar powered batteries.

Me and the kids quickly grabbed a table and set off to work.


Try 1: Our first version was to build a rover with the smaller wheels attached to the motor. It was a push model i.e. the back smaller wheels pushed the Rover. We did very badly with a 18.47 seconds.


Try 2: We decided to try attaching the motor to the bigger wheels and this time it was a pull model. We did way better with 8.89 seconds and a 4th place.



Try 3,4,5: we tried to improvise the design by reducing the resistance, however that did not give us any advantage(I guess the model became less stable).Since we wanted to explore other areas on Chabot we concluded our efforts.


There were demonstration booths set-up where the voluteers were high-school students. Two such activities were identifying meteorites (the charactersitics were given) and making soap bubbles with dry ice.
