Sir Spinalot

This is slowly turning into a good first vapourbot. The basics are there but there is much more you could expand on. The way I see it, the more information you pack in, the easier it is for the writer to understand how it will perform.

First of all, you may be surprised how large heavyweight robots actually are. I would suggest making the diameter somewhere between 700mm - 1000mm. The robot does not need to be that tall either. For this, I€™d suggest around 200mm in height. Bear in mind the diameter of your motors will mean few robots are under 150mm tall.

Which brings me onto the next problem - LEM300 motors do not exist. The Lynch Motor Company or LEMCO produce 3 motors that I am aware of - the LEM130, the LEM170 and the LEM200. Although obviously correct me if I am wrong here. I believe you would probably be referring to LEM130 motors. These would be a good choice for drive as they are incredible light for such a powerful motor. At 24v they give similar performance to a Bosch 750, which weight twice as much. At 36v you can get huge amounts of power out of them, but being as you are circular in shape I€™d stick too just 24v. Alternatively, you could also look at Magmotors, particularly the S28-400.

Ground clearance is something which is usually difficult to grasp for newcomers. 0mm effectively means that you cannot move. 0mm clearance is only really capable by using wedge that run flush to the ground, whether these are fixed or skirted. And being as your robot has neither of these, it will require higher. High ground clearance isn€™t such a bad thing. Being as you have the spinner providing gyroscopic forces and a self-righting bar, it isn€™t much of a problem anyway. With spinners, it is also likely that debris will be caused on the arena floor, which you would have to drive over. Therefore you would probably need at least 8mm of clearance, and I€™d suggest 10mm to be safe.

For the weapon you need a few more details. For a start it needs to be a lot bigger so it can actually hit opponents. Secondly, how do you fit 10 teeth on to a bar? Again you€™ll need to change the motors, as with the drive motors. For the self-righting bar, where is it positioned and what powers it?

If you can fix all of this stuff, then a few more details can be added. Good stuff so far though!
