Simulating a Humanoid Robot (Fun with PhysX Joints and Transforms) Part 2
Ok,
So it looks like my assumption was correct that manipulating the individual segments directly, somehow bypasses the physics calculations.
I actually managed to rig my model with configurable joints and make the joints stable ( no jitter ). The biggest gotcha that I found is to make sure that the colliders that are attached to [...]

Simulating a Humanoid Robot (Fun with PhysX Joints and Transforms)
Over the course of the last few weeks I have been developing a humanoid robot simulation for robotSim
This has not been a very easy task and I seriously thought that it would take a lot less time than it did.
After getting all of the kinks out of the 3d model we started to rig the [...]

Simulating Joint Torque on a Humanoid Robot Part 1
Simulating humanoid robots are not a simple task. I have been working on simulating joints and discovered that the current PhysX engine does not implement certain functions and that this will change the way we simulate joints.
Currently PhysX cannot report back how much torque is being applied to a joint, so there is know way [...]

Simulating a Humanoid Robot Pressure Sensor (foot) Part 1
I have been working on simulating a pressure sensor for humanoid robots. Pressure sensors mounted on both feet of a humanoid can provide a measure of how the weight of the robot is distributed across its entire body. This information is useful for humanoid robot balancing and stable walking algorithms.
There are a couple of different [...]

Swarm Research using Trackbot and Visual programming
Last Thursday I received two new Trackbots( latest hardware / firmware version) from Systronix with the virtual intelligence adapter (Bluetooth comms). I think these new Trackbots will be able to communicate with each other using their built-in LED beaconing systems.
On Friday we verified that we could indeed get both of the Trackbots to communicate at the same time to one Computer. We verified [...]
