Re: RogueTwo Robots
Update
Happy New Year everyone! You're always best to start the year the way you intend it to continue, and for me that was in my shed building robots.
Unfortunately I never got any work done to the tracked grabber over Christmas, mostly because I pinched the actuator for Carcinus which, after choosing to retire it, I changed my mind and decided to rebuild. Partly for demos at Scot-Bots events and partly because I didn't want my dad driving the cool tracked one
The baseplate was shot to bits though, having been hacked up several times in various internal rejigs. So that's been remade from a piece of 8mm HDPE, as has the top panel which was previously 6mm MDF.
As mentioned, the previous homemade M12 actuator that was in there has been taken out and replaced with an 18V GLA-S actuator. Only 50mm stroke so the claws don't close that much, but should be enough to contain most robots:
As well as a sturdy mounting bracket at the rear, I've also made a Nylon block to fit round the front of it. This holds the whole actuator securely to the robot and makes the setup more solid than it's ever been. Those actuators are also fast!

The downside with a GLA-S actuator is that the limit switches have been removed as they don't work at higher voltages, but I'm going to have to make some up otherwise I predict much self-inflicted damage with this version. They've got a decent amount of force in them too; whether it will make much difference in the arena though I don't know!
