Go-Kart

This is the first build of Round Two and it incorporates the new bodgit game. However, the teams still have just 6 hours to build a go-kart. It doesn't have an engine but it will be pedal powered. Each team will run a four person, two stage relay race that tests the steering and speed of the karts. The first person pedals up a straight-away to the second teammember who will replace the first driver and navigate a twisty leg of the track to the waiting third teammate. The third person will race back through the twisty turns to person number four. The fourth person will take the kart back down the straight-away and across the finish line. The first team to do so, advances to round three.

Each team will need a chassis, wheels, a pedal unit and steering. The chassis is the body of the go-kart that everything will attach to. The steering is important because of the winding part of the course but it also determines where the drivers will have to sit so everyone can pedal the kart comfortably. The pedals are the most important part though...that gets the power from their legs to the rear wheels to push them along. The will need to put a sprocket (a wheel with teeth) on the rear axle and run a chain from the pedals to the sprocket. If the chain is too lose, it will slip off. If it's too tight, they won't be able to turn the pedals (or even worse...break the chain!). Using the proper length of chain and the right sized sprocket could make or brake this race.
 
 
 
Rob shows what the course will be.
Each team won 10 minutes of
engineer time.
The go-kart the teams are building
is a lot like a bicycle only with
four wheels
 
 
Red is making a custom chassis
Blue uses a medical helicopter basket
 
 
Getting those pedals in the right spot
is critical or else there might be too
much slack in that chain
Red has a seating problem. Where
the seat goes is also important because
there is a 7" height difference between
the teammates
 
 
Oh no! With 2 minutes to go, red
breaks their steering wheel
And blue adds support because they
bent their frame a little during a test
 
 
At the speedway, blue takes an
early lead
Red made a better driver change
and now they have the lead
 
 
Blue is off but the chain is slipping
Red increases their lead
 
 
Blue makes the change to the third man
Red is starting the home stretch
 
 
Red wins and goes on to Round 3!
Blue finishes the race despite the loss
