Our first idea was to create a tracked robot able to climb stairs and plenty of others obstacles, to reach a good speed (around 10 or 15 km/h) while filming and transmitting data. It will decide itself if it can go through an obstacle like a slope, stairs or a hole. Recognizing people and following them, take panorama pictures, follow a GPS designate way are its objectives.
Step 1: Chassis
Step 2: Tracks
We used :
- 4 bicycles chains that a bike store gave to us (they are about 140/150 cm)
- 4 identical gearwheels that we bought near 5 € each
- aluminum rod (about 2.5 m)
- rubber (quite the same length than aluminum rod).
We attached the chains by pairs with the aluminum rod and wire and then we attached the rubber to them.
Power wheel are made of 2 gearwheels with one wooden disc between them. Be sure to have the same space between the chains at every new component you add, then you can circle your chains.
Here is our first test od the tracks !
