I have been doing some modifications to the front of Cherub as it has problems moving with another robot "on board."
The reason is the front of the robot is weighed down too much and the front plough digs in the arena floor and stops Cherub from moving.
If I make the front higher then I would not get under anything and if I leave it I won't be able to move to drop the robots that has been caught into the pit!
The solution to this is to have retractable front wheels.
I have fitted to the lifting shaft, a cam that engages the follower that is attached to another set of wheels under the front of the robot.
When the lift arm is horizontal the cam is disengaged and the robot is on it's castors as normal, and when the arms are vertical the cam is fully engaged lifting the front of the robot about 8-10mm off the arena floor!
This should be enough to release the front of the robot and make it possible to move with the extra weight.

Not much happening on the forum at the moment so I thought I would just write a few things down.
The Maidstone weekend
This was a very good weekend for Team Saint we won the qualifier fight with Eruption. Zack’s driving was a master class in axel bot control, and the fight with Ripper was a little unlucky as Saint was winning up till it was ejected out of the arena, and as soon as Saint left, the drive on Ripper failed on one side, if only it had bounced into the arena!
The Ti Broad Sword was a big (please forgive the pun) HIT!! We are defiantly keeping that puppy:mrgreen: The advantage is Saint doesn’t have to get too close to the opponent as the sword is 4 feet long!
Cherub Got out of the pit exactly as I had designed it to, well chuffed.:mrgreen: Also the retractable front wheels didn't break and it seemed to cope with a rather uneven floor so that's all good.
Seraph did stop in some of the Feather fights. I am going to change the wiring completely and try again, still waiting on some parts for the new Seraph hopefully it will be playing in the New Year.
Tron did well again noticed only by me, driving still needs work, I am still not happy with the battery, I may go LiPo.
I am starting to do a few bits on the new Saint too Hope to get that going before the end of summer 2014.

Which motors do you use in Seraph?

Here are some pictures of the motor gearbox drives for Seraph. I don't know the power of the motors but estimate about 150w. Bottom line they are more powerful than we need! we tend to run Seraph with the DX5e Tx on the low setting and a deliberately low capacity battery pack. even then we have more than enough power the wheels almost never stall. I believe these are the same motors used in motorised golf trolleys.
