Probably more to it than just making an extended top - the capacitive touch switches, LEDs and so on would need extending from the main circuit board to reach the raised top.simplesi wrote:A Raspberry Pi joint case might be the cheapest /easiest solution as it could still have the top sensors.
Puts hand up - yep, 3d printer owner here - can be had for < £500 now.Ravenous wrote: The more advanced hobbyists can often get access to a 3D printer these days too.
There is an ongoing discussion on porting Scratch on Thymio, and ongoing developments to have a wireless Thymio....simplesi wrote:I want to see a market for £50 -> £100 educational robots programmed using a block programming language like Scratch (preferably in Scratch)
Scratch could be indeed a nice intermediate programming environment between VPL for pupils and the text programming environment of Aseba Studio.simplesi wrote:Yes - the visual programming enviroment is easier than Scratch and would be useful for younger pupils.
But I'd like a bit more for older pupils and since Scratch is what they will be learning to use for normal Computing - it makes sense to use it for Robotics as well.

£7 is extremely expensive, for this product we need to be within the few $ for this type of functionality. And certifications are a real and costly problem....meltwater wrote:Regarding bluetooth.
If the controller has serial pins, then a bluetooth module would be easy to add for around £7. The firmware would just need to respond to serial commands, as it would to USB commands.
IR comm among robots is already implemented and included in the firmware, but the bandwidth is much lower!meltwater wrote:Regarding bluetooth.
Although, the IR link may be a simpler method, wouldn't take much for a device to take serial output from a bluetooth module and convert it to the IR signals expected by the robot.
No, sorry. Would probably cost (in small qualities because of the market) the same price as the robotmeltwater wrote: Q: Would the controller board be available to purchase separately?
BT is expensive and complex: either you include a full module and this costs a lot, or you need to certify and this is complex and costy. We are studying this in detail since long time and have already a working solution.meltwater wrote:That is a prebuilt bluetooth serial module, so cost price would probably be much lower if built independently. However, the certifications would be an issue (which I think is why the RPi did well to avoid built in wifi and bluetooth - despite broadcom being market leaders in them).
Depending on if you directly wire into the IR line (I guess it is IrDa - although didn't spot the IR transmitter line in the hardware), the data rate could be increased if not going through the IR sensor. Although it could be made as clip on module instead. For basic control, the data rate might not be a huge issue.
If one set of the serial pin connections were available (appears to be 4 uarts on the PIC), then it would just be a serial bluetooth module that is required (within the firmware I imagine it would be possible to send the data to the same handler for the IrDa). Standard Bluetooth modules, sourced and sold separately, would probably avoid the certifications. Bluetooth would add support for control via Android as well as the Rpi and wireless control for PCs too. For apple support you'd need BLE modules (which I've not looked at so far - they don't seem to be as easy to get and in Apple tradition, not as open support as Android).
Hopefully if the market expands, then boards will be made available too, as they would be very useful (not least by presenting a standard platform for controlling things). Would make a nice RPi addon.
Don't forget they are also used for low bandwidth communication between other bots - classic swarmbot stuff - maybe play search party or something like that...meltwater wrote: The IR stuff sounds interesting, they are quite useful in that sense for proximity and detection. Via analogue inputs quite a rich source of information. Leveraging extra information out of basic sensors is a neat way to make the most of the hardware.
