Hi
Limor meant to post already the Blog entry of assembling the Bioloid Premium we have received.
We have TONS of pictures of the assembly process, parts included, etc.
Just to summarize the cool things there:
- No more AX-S1 sensor - you still get sensors but they come separate and not in a single unit.
The sensors are attached to the robot using OLLO parts (they seem to have been inherited from OLLO).
- There is now a new Frame type that does the "adaptation" between the Bioloid frames and the OLLO frames and it's quite flexible.
It let's you assemble the sensors in many different places easilly.
- The sensors now connect directly to the GPIO ports on the CM510 controller.
- Also a Sharp IR sensor is included and placed in the chest and ina ddition there are two more IR sensors (not Sharp;they seem the same type that are assembled onto AX-S1) that you can place wherever you want using the OLLO parts.
- The new CM510 controller uses an ATMEGA from the 256 series.
It exposes 6 GPIO ports.
The pinning for the GPIO is: Vdd, GND, A/D and one DIO pin that you can set High or Low.
The ports can be used for these or any other custom sensors you may wish to use, making it much more flexible.
- Another cool thing of the CM510 is that it exposes a second UART externally.
It has connector where you connect the IR receiver or the Zig110 module.
Alternatively you can use that port with any application you want.
A Remocon library is to be released with the syntax of commands that can be fed through this UART to the standard firmware.
I'm still a blurry on what can be done through that port with the standard firmware.
However one of the things you can do is replace the firmware with one that simply passes information back and forth to the Dynamixel bus (you need to write this yourself though). This way you can talk to the bus using this port that has RX and TX clearlly separated (and therefore dispense the need for hacks to talk to the one wire Dyynamixel bus).
- One of the cool new additions is the new S20 sensor.
This sensor (which is a PCB in the picture) uses an integrated chip that has a 6 axis IMU: 3 axis from accelerometer and 3 axis for a magnetometer.
Theoretically the magnetometer would offer similar information to a gyro but from what I've heard both here in the forum and at the Robotis office, the Magnetometer may be subject to influence of the servos working.
Again, Limor has the details and specs on the chip used.
- Also the S20 sensor seems to have a little noise. They claim it has internal stabilization but if you place the robot still and open Roboplus Manager to watch the readings in real time, you can see some noise.
I suggested to Robotis that they implemented an additional set of IDs to offer the values already filtered by the onboard ATMEGA on the sensor, because if you'll be using Roboplus to program the robot, stabilization of the values does not seem to be the best of tasks for Roboplus...
However they did not seem too receptive to that right now. We'll see.
- Also, the frames are new.
They are the same colour (which makes it hard to differentiate them) but I was told they are a new material that is lighter and more robust.
- There is something new in the Robot because the servos hold torque very very well.
I can post a video of the robot I took, holding an extremely low position (with the knees at about 150~170 degrees) and the servos hold the weight of the robot amazingly. You can even press the robot head towards the ground and it holds torque and position amazingly compared to the Limor's Comprehensive Bioloid I worked with.
They claim there is no firmware change so I would assume this may be due to the higher voltage of the LiPo OR a different setup of parameters as well (the parameters for compliance, etc) OR maybe it's the new Roboplus Motion that by default adjusts them to improved values.
The Farrels suggested that we connect the LiPo battery to the old Bioloid to see if it's the voltage that improves servo behavior but unfortunately the connectors are not compatible and I wouldn't want to be messing with our brand new Bioloid
- The Premium Kit also includes the RC-100 remote but by default it works over IR.
Installing the Zigbee upgrade is trivial as you simply need to remove the IR receiver from the head and replace it with th Zigbee one.
They connect to the second UART port that is now exposed by the CM510.
The zigbee pair that goes into the RC-100 is simply inserted into place and no soldering is required.
- Additionally with the Premium Kit you get a USB2Dynamixel.
- There is also another extra/Optional item which are the Aluminum feet. These are a bit larger than the traditional Bioloid Feet and seem to perform better in gaits.
---
Also, as you may know there is a new upgrade kit coming for Bioloid Comprehensive owners.
The information bellow is preliminary as I don't have final confirmation from the manufacturer. I am stating my understanding and the final list may (and most likely WILL vary)
Contents of the new Comprehensive -> Premium Upgrade Kit (preliminary info that will change):
- New set of frames (same colour but different material; the chest frames are also very different)
- The new chest cover
- The new head
- USB2Dynamixel
- New CM510 controller
- LiPo and LiPo charger (not sure if the power supply is included though. The power supply is the same as in the Comprehensive. You can connect it directly to the robot or connect it to the LiPo charger for charging the batteries).
- New set of Sensors (not 100% sure on this one though): Sharp and 2 additional IR.
- RC 100 remote + IR receiver for the head.
I think that the only thing you keep from your Comprehensive Bioloid are the 18 servos, the power supply and the Serial Cable.
I believe all the rest will be new (respecting the same part list as a complete Bioloid Premium Kit) but I will advertise the final info about the Upgrade Kit once I have it.
