|A very large tank, meant to be used as a modular platform for future projects.|
|Manager||Edward White, James Parkin|
We are creating a large robot tank which can act as a platform for many future projects. The tank will be able to travel great distances and at great speed over land, and will also be water-tight: allowing it to be adapted into an amphibious craft. The tank will have surplus power, ample empty space within its structure and a flat top allowing it to be used for many new projects in the coming academic year.
Design goals are:
- Very robust!
- Ability to traverse almost any terrain, including stairs
- Adaptable to many different projects, such as:
- Adding a Kinect, to make it roam autonomously and avoid obstacles
- Portable Quadcopter recharging unit / Aircraft carrier
Other concept ideas
CAD Design halfway there!
The track system will be based on 2 parrallel motorbike chains with
metal bars half pvc tube segments screwed across them.
- We were considering using 4 of the following chains. They are 1770mm long.
- We will power the tracks using two of these drills
- Quick guess of required main drive shaft torque: 200-300 Ncm
- Dimensions of tracks are: between chains 34mm, chains are 15mm thick, pipes come out aprox. 6mm outside of chain.
The main body of the robot will be similar to a boat in structure and contain a lot of empty space for use in future projects.
