This year we are again adding audio to our mini dasher-bot. In a similar fashion to last year we started off using the same mini class D 5v amp ( see last year’s post). By hooking it up to 5v + GND pins to drive some 4W speakers. The sound was fine and plenty loud. […]

Trials and extra sensors

Yesterday we continued to train up some of our club members to try out some of the obstacles using the Wii_mote_nunchuck controller. The results were very good, with some steady manoeuvring around a makeshift golf course ramp and mini obstacle course. The servo golf ball gizmo worked well. In addition to the training, we were also […]

Golf Gizmo

We’ve been trying out a 3D printed “golf ball catcher” thingy – based on the simple prototypes designed before 1/2 term. The idea is of course, to trap the ball as it descends down the slope and around the course. A servo provides the automated lift. We tried out the design on a simplified gold […]

New (Astro) Moto!

Last week I decided to replace our older Model 1B Pi’s with a spanking new ZeroW + a PiZ moto Driver board. This board was purchased last year from Mark Cantrell (ASTRO Designs) who runs the micro-pi-noon robots @ Cotswold CAMJAM. Here it is on a tracked robot chassis. This gives us more room, and flexibility […]

We continue to fettle the CAMJAM code to try and get DiddyDasher around the course smoothly. Still much work to do, but progress is being made. See it in action below and a clip of the maze in use at the Cotswold Jam last weekend. One of our roboteers (Alex) is trying to set up […]

Maze @ Cotswold jam

On Saturday Jan’ 27th we’ll take along the maze to the next Cotswold Jam to try out / let others have a go! The Cotswold Jam organisers have given us permission to set up the maze and run some through some code tests using the CAMJAM kit code + ultrasonic sensor. Come along (book on website): […]

BlueDot controller

We’ve been experimenting over the past few weeks with the BlueDot smart phone bluetooth app. On first impressions it runs quite well! I did have to flash a SD card with a Stretch OS image, then add the necessary drivers as per the read the docs instructions. Pairing and linking the phone to the Pi […]

Refine that Design

Here’s a quick update to the design of our A5 DiddyDasher. Our Stem Ambassador (Ernie) has 3D printed some brackets to hold the ultrasonic sensor in place. I’ll cover that in more detail shortly. You can see that the 6V battery pack for the motors sits well alongside the wheels – whilst the 2X Poundland Pi […]

Contender?

We won a CBiS 4WD robot at the Pi-Wars last year. We’ve been having a play! There’s been a few hurdles to overcome – which may now have been jumped! Firstly we proved that the original design does not steer – using the above axle configuration. Secondly, we found the included scripts to confusing […]

New chassis evolves

We’ve been honing the chassis design for a few months now. The design had to be easy and cheap to assemble; eliminating extraneous fixings. We also wanted to make sure it fitted the 6v DC motors that came with the CAMJAM kits. We were always keen to move from 2WD to 4WD using a simple […]
