Building the seating buck

26 Apr

After an initial session getting a feel for the overall dimensions of our vehicles, St Patrick’s College is about to start building a “seating buck”, which will enable us to refine the layout, dimensions and construction methods. Whilst doing so, they will draw on ergonomics data developed over many decades for conventional vehicle design.

When seeking to avoid reinventing the wheel, it is appropriate that the first major component we have selected is the wheel. At last night’s design workshop we considered a range of ATV, motorbike and downhill mountain bike wheels and we agreed that we’d use lightweight ATV tyres on pressed aluminium ATV rims, like this:

Driving on dirt

25 Feb

Yesterday afternoon, a group of us took Trev out to a dirt track and measured the energy required to drive on dirt. Trev with one person in it has a mass of about 400 kg, which is about the target mass of our African Solar Taxi with three people in it.
