Maybe not a big surprise to report we have fallen behind against our original plans and schedule, nevertheless we are determined to take part in the competition this year even though our entry may not be as polished as we hoped.




1. We have redesigned the sides to improve the means of mounting the attachments and added the robot name while we were at it.







2. Multiblock pincer - we have designed a new pincer capable of collecting and dropping all 3 blocks in one go for the tidy up the toys challange.






3. Anthony captured some nice animations from his 3D printer... here is one of the chassis plates being printed.





4. Motors - we were finding the stepper motors we were using a little bit "weedy", especially when in "full step" mode and under higher torque loads like when skid steering, the motors were missing steps. So control accuracy was suffering. We therefore upgrade to higher torque motors and upped the supply voltage.

So here is where we got to prior to the cancellation of PiWars 2020 in March.

Main changes we will make for PiWars@home are:

1. Feed the Fish - lobbing nerf darts with our modified nerf gun might not work very well when the fishbowl is so close, 360mm. Its way too powerful and designed to smash zombies. We could turn it down, slow down the motor, but we're not sure how well it will work or how accurate it will be doing that. Need to do some experiments.

2. Tidy up the Toys - We will have to adapt our pincer to grab cubes (not round barrels). The camera is well positioned for doing this task autonomously. All it then needs is some software.... should be a doddle! ;-)

3. Up the Garden Path - Previously we got the line following software working well for the Lava Palava challenge, however this new challenge has some added complications, radiused 180° turns and several dead ends to lead us astray. A downward facing camera dead centre will help with the automation but that's going to get in the way of the main motor battery... we might need to rearrange a few things there.

4. DIY Obstacle course - This will just be pure fun! :-)
