  1. My intention with the post is to correct the speculation regarding the performance of the timing hardware. We have no interest in which events or timing partners that make use of our system, our focus is on development and introducing new functionality to the system. Regardless of which timing system is used, an event can only be successfully timed if registration data entered into the system is correct and controlled properly, race packs and tags are correctly packed and assigned to participants according to registration data, timing equipment is configured correctly and sufficiently skilled trained timing crew is available at the event. When results need to be imported into a third party program before updating on a website then you automatically start working with disconnected data. We have worked closely with this timing partner in some events and he always provides a professional service. However, to be fair, he was not in control of all the factors that lead to a successfully timed event.
  2. Thanks for the reply, I will explain one of the aspects. On the first days of the event, the pods were not configured correctly for Road Cycling. They were configured to wake the tags and ask them to transmit at 50ms beacon intervals instead of the recommended 10ms intervals when approaching the finish line. This means that as each cyclist approached the finish line, the Pod on the line with the incorrect configuration setting, was not able to produce a result from some tags as we require a minimum of two reads per passing to produce a result. The raw data, when analysed, by our team after the event, showed many tags with individual tag reads for each registered tag per passing which we ignore. Typically we set this at a 10ms minimum level for Cycling and in motor sport where, for example, a Super Bike may travel in excess of 270 km/h, the pods should be configured to wake tags at 1ms intervals when passing over a line. With the incorrect settings applied, some tags where thus not read in the event to produce a result, but individual beacons were. One of our crew attended Stage 4 and configured the pods correctly, having come from the Cape Rouleur in the days before and tags operated as designed, however, with the other factors affecting the timing from the previous days, it is almost impossible to recover at that point so late in the event. There were many other contributing factors at this event, this was one of them.
  3. Hi Everyone, a bit late to this topic but was asked to take a look here. Our system is absolutely rock solid in reading tags, the hardware is regularly tested internationally to read up to 400 tags per second, so I don't know where these statements are coming from. There is no similar system in action anywhere globally and everything is designed and developed by our team in Cape Town. We are developers of the system and will only be present at events where we train customers how to use our system, from there onwards we have no influence or control over how the event is run. I have actually followed the background to this event and believe me when I say that there were factors outside the control of our timing system that lead to problems at this event. In terms of raw performance, tags were read as designed, but there are other components to making the timing of an event successful apart from the hardware. If you want to understand more about how the system works from a technical point and why this is the future over traditional expensive mats, then here is a video taken from a Road Cycling event that we attended and documented: Our system is now actually used internationally in 12 countries representing sports from motor racing to kite surfing. Happy to answer any technical questions you may have.
  4. Hi Yumeya Sorry to hear that you lost your Motion M01 GPS. If you can't find your device, then call us at the office tomorrow and we will try and make a plan to get you up and running with another device.
  5. We have added a new blog site with tutorials as well as downloads with extra content that you can share and use with the Motion M01-1. It is still new but will grow rapidly. http://blog.mobii.com We are going to be loading up, for example, setup files for precision timing different MTB routes with the Motion M01-1. If you have some files of tracks you want to add, you can send them to us.
  6. Thanks for the message Yumeya It was great having you around yesterday to take a look at the Motion M01-1 and the Motion Experience Centre, I am sure you will have a lot of fun with your device. If anybody else wants to demo the Motion M01-1 then you are welcome to visit us here in Cape Town.
  7. If you send us an example file of the output you would like your data exported to, then our developers can implement that file export structure. In general, if there is a broad need by our customers to implement a specific feature, then we usually do so quite rapidly. Our device is used in many, many different types of sports so there are always new features being implemented to cater for different sports.
  8. Hi Rouxtjie You can use any video footage supported by Windows Media Player to merge with your data. There is no built-in camera on the Motion M01-1. All you do is: - Record your ride with your Motion M01-1 and video camera (Eg: GoPro) - Synch the data to the Motion Experience Centre - Go to "Playback", select your overlays (Maps, Markers, colour settings, graphs, data overlays etc) that you want to see - Open the video control, load the video and synch it - Then press play. You can also view the video in slow motion (1/4 and 1/2 speed) with all your data overlaid. You also overlay your video onto a map as well. As mentioned in an earlier post, you can export to MBI (Our binary format containing all data) or GPX (Position data and HR only). We can view this data in Sport Tracks or Endomondo. If there are other formats people want us to export the data to then we can add that in. If you link photographs, notes and weather information with your activity then you can export this in our format so others can view everything in the Motion Experience Centre. If you want to download some example files to play around with in the Motion Experience Centre, then you can download a zip file containing some example activity files here http://www.mobii.com/files/MEC.zip The file is from one of our sponsored MTB riders who rode “Die Burger” MTB race. To import it: - Go to “Activity Review” - Click on the import button next to the green playback icon and select the mbi file attached. - You have the option of importing the entire profile, you can do so to view energy expenditure information on the rider. - View the graphs by clicking on the round buttons to the right of each graph. - Go to “Playback”, by clicking on the green icon at the top left of the screen. - In playback, you will need to activate a map layer, click on the cogs in the playback bezel and then go to the map layers tab. Select “OpenCycleMap” to get the map layer with relief data. The second file is a motor racing example. To import it: - Go to “Activity Review” - Click on the import button next to the green playback icon and select the mbi file attached. - You have the option of importing the entire profile, you can do so to view energy expenditure information on the rider. - View the graphs by clicking on the round buttons to the right of each graph. - View the laps by clicking on “Lap Summary”, you can also view it full screen by clicking on “Full screen summary” - Go to “Playback”, by clicking on the green icon at the top left of the screen. - In playback, you will need to activate the Killarney map layer, click on the cogs in the playback bezel and then go to the map layers tab. Select the button named “Add Layer”, then enter a name called “Killarney” and the Tile URL will be “http://maps.mobii.com/Killarney/Z{z}/{y}_{x}.png”, click accept and use that layer for viewing the custom Killarney map layer. Have fun trying it out.
  9. Here is a screenshot taken from our Motion Experience Centre. You change the colour of the shaded tail to reflect any metric's intensity. You can also change the actual moving marker's colour as well based on any metric we record.
  10. Hi Edman Thanks for the interesting questions, you seem to have a good understanding of the device already. To answer your questions. [*]Does the device have an option to record torque values transmitted by a power meter that has the capability? The ANT+ device profile for power transmits Torque and Cadence and we use those values to derive power. Now this also depends on the type of ANT+ Power meter you are connecting to, there are different variations of Power meters: - Power only - Wheel torque - Crank Torque - Crank Torque Frequency We calculate Torque depending on the type of Power meter that is connected and then use a formula specific to that type of equipment to derive the actual Power value, which we store. So at this stage, we use Torque merely as a means to derive the power. We currently do not store the Torque value, but we can easily add this to our data storage format if there are people who would like to view this metric. [*]Does the device handle cadence and speed values transmitted from a power meter e.g. a Powertap? We currently store cadence from the Power meter, not the speed value. We do however store the Speed value from a cadence sensor, but in general GPS takes priority over all equipment used. If you disable GPS for a specific activity, then we use the Speed value. We will be adding a firmware update in the future that stores the speed value from a power meter. [*]If multiple devices are transmitting the same data e.g. speed from speed sensor, from power meter and from GPS, how does it prioritise them or does it record all of them separately? GPS is prioritised, if GPS is disabled then we can use the speed value from the Power meter. [*]Will the device work with speed-only or cadence-only ANT+ sensors or will it only work with combined speed/cadence sensors (a different ANT+ profile)? Currently the Speed Only sensor is not added, all the others are. It is alo being implemented as a firmware update soon. [*]Does the device separate g and tilt values e.g. if I'm braking on a flat surface, will the tilt remain the same or will it shift due to the changing acceleration? The accelerometer will output a single value which we use to derive both G's and Tilt. If acceleration or decelleration values are less than 1 G, the sensor will not be able to accurately distinguish between tilt and acceleration. A gyro accessory is planned to be released which will enable the device to distinguish between acceleration due to velocity and tilt due to gravity. [*]Related to the above, is it possible to use the tilt meter to determine gradient (obviously given a stable mount and an initial calibration)? Yes, the tilt value can be used to determine gradient. At the moment there is no calibration function, but is a work in progress that will allow you "Zero Calibrate" the Tilt value when the device is mounted. [*]Does the device allow me to use advanced custom workouts e.g. on my Edge I can program a workout with multiple intervals and sub-intervals, based on time/distance etc., all with different targets? There is functionality to handle this in what we call Action-Triggers. This allows you to set "Action-Trigger Sets", each set can contain up to 32 Program Instructions, Each Instruction can contain up to 8 Triggers based on data or location variables and when the triggers are true you can fire off up to 32 Actions (Play audio, display specific displays, New laps, Pause, etc... List is endless). [*]The brochure mentions using two heart rate monitors on different channels. In this case, or if I were to use two power meters, how does it record the data? Does it record separate HR or power values for each one? You can connect up to 4 ANT+ devices. Whether that is 4 HR straps, or two power meters and two HR straps. The first of each equipment type paired in the Equipment group will be displayed on the device and you will be able to create Action-Triggers on those items. The remaining sensors of that 'Equipment Type' will be recorded and the data will be displayed in the Motion Experience Centre. [*]What format are the device's data files? Can I upload them to a 3rd party program like Sport Tracks or WKO+? Does your software have an option to convert the data to .csv format for, for example, further processing in Excel? We store our data in our own binary format. There is no way you can store 1/4 sec GPS data, plus Accelerometer data in traditional XML based formats. We do allow the export of data to GPX, which you can then import into 3rd Party software programs. GPX data we export contains the Position data plus Heart Rate data. You can import this data in Sport Tracks. We allow for data to be exported to CSV, but this is used mainly in the High-Performance code base, which has not been merged into the public release code as yet. [*]Your brochure and website say the price is R2695, but the shopping cart says R2995. Which is the correct price? The price was adjusted last week to R2995 as the introduction price had ended.
  11. Hi Ricochet_rabbit We chose to go the route of joining the ANT+ Alliance and developing the Motion M01-1 to be ANT+ enabled for a number of different reasons. The main benefit of using ANT+ is the low battery power consumption and the ability to use sensors from a multitude of 3rd party manufacturers providing customers with greater choice in terms of what kind of sensors they would like to use. Also, if you already have ANT+ enabled equipment form another manufacturer, then it means you don't have to buy duplicate pieces of the same equipment types. ANT+ device profiles are exanding rapidly and these profiles are continuously supported by the Motion M01-1 in the form of updated firmware which is released on a regular basis. We also use ANT+ for proprietry communication with sensors which do not fall into ANT+ device specific profiles. For example, we used it recently during the Dual Slalom MTB race arranged by the Tygerberg MTB club to record accurate lap timing using our Virtual Intersects system and broadcast it live to a computer as each rider crossed the finish line.
  12. We are in the Northern Suburbs in the Tygervalley area. Unit 6 Bella Rosa Mini-Factories 30 Bella Rosa rd Rosenpark Here are some pics of our setup taken a few months back http://www.facebook.com/media/set/?set=a.227668153916018.75198.112875998728568&type=3 We pretty much do everything under one roof, from electronic design and assembly to injection moulding the plastic parts and software development. If you call beforehand, then we can arrange that one of us is available to give you a full run down on the capabilities of the product and software. (021) 914 6982 We have spent the last few months launching the unit and you will be hearing more and more about us, I am pretty sure of that. There is also a gear review that came out in the magazine "Modern Athlete" this month.
  13. If you are in Cape Town, you are more than welcome to visit our office/mini-factory and see the unit in action. We can also help you get started and set up Action-Trigger sets, which allows you to program the device with some advanced features.
  14. Hi Yumeya Currently we stock our products via our website at www.mobii.com, after an order is placed the units are couriered out. We are still in the process of having retailers stock our units. In terms of which Speed/Cadence sensor would suitable, you could try a Garmin ANT+ Speed/Cadence sensor. We have a number of customers using these at the moment and the added benefit is that you can have speed & distance recorded when training indoors.
  15. Yes, that is Stefan Senekal riding with Team Falke. The guys have been using our device for quite some time now. He was doing really well until one of the guys in front stopped suddenly and he ended up going into the back of the stationary rider. We had the GoPro camera on Johannes Scribante who was also using our device. What you see there is the ability of the Motion Experience Centre software to synchronise your video footage with your data overlaid on top. It allows you to run the video back in slow motion as well to analyse your data along certain sections of a recorded activity. So you can, for example, see how fast you went through a particular section of a course and watch the video with the data on top to prove it!
